10 TECHNICAL INFORMATION NORMAG - LABORATORY GLASSWARE L 300 e.1

11 TECHNICAL INFORMATION GENERAL All in this catalogue described semi-finished products for manipulators as tubes, tubing, connecting pieces (e.g. with grinding, flanges), stopcocks and valves, and all ground devices (e.g. column components), components (e.g. reaction vessels) and apparatus are made of Borosilicate glass 3.3, the common material in technical glass construction. Remarkable features of Borosilicate glass 3.3 are an utmost chemical resistance to all media, a low thermal coefficient of linear expansion as well as its resistance to temperature. All our products are recognisable at our brand: This brand stands for: - After taking over the NORMAG - Labor- und Verfahrenstechnik GmbH and its know how we supply semi-finished products for glassblower as ground devices, components and apparatus for laboratory technique in the well known and recognised excellent quality of this company. - The supplied products are only manufactured from Borosilicate glass 3.3, the only material we use in our production. This is also valid for those semi-finished products (tubes, rods, ground ends) which are not marked because of technical reasons. - All dimensions without tolerances indicated in this catalogue are mounting sizes and serve only for orientation. PROPERTIES OF BOROSILICATE GLASS 3.3 Chemical composition The used Borosilicate glass 3.3 for glassware has approximately the following composition: Component % by weight SiO B 2 O NaO 4.2 Al 2 O Trace elements 0.5 The very wide use of this material in the chemical and pharmaceutical industries and in other related areas bases on the chemical and thermal properties (see DIN ISO 3585). These properties together with a great number of other benefits distinguish Borosilicate glass 3.3 from other materials of construction. The special characteristics are: - Smooth, non-porous surface - Catalytic indifference - No adverse physiological properties - Neutral taste and smell - Non-flammability - Transparency 2

12 TECHNICAL INFORMATION Chemical Resistance The chemical resistance of Borosilicate glass 3.3 makes it much more comprehensive than that of all other known materials. It is highly resistant to water, salt solutions, organic substances, Halogens as Bromine and Chlorine and many acids. Exceptions are hydrofluoric acid, concentrated phosphoric acid and strong alkaline solutions. They cause appriciable surface removal at higher temperatures. But Borosilicate glass 3.3 can be employed at ambient temperature for solutions up to 30 % concentration without problems. Classification of Borosilicate glass 3.3 according to the relevant analysis methods: (see DIN ISO 3585) Hydrolytic resistance at 98 C Hydrolytic resistance grain class ISO 719-HGB 1 Hydrolytic resistance at 121 C Hydrolytic resistance grain class ISO 720-HGA 1 Acid resistance Deposit of Na 2 O<100 µg/dm² to ISO 1776 Alkali resistance Alkali resistance class ISO 695-A2 Physical properties Borosilicate glass 3.3 differs from other construction materials not only because of its almost universal corrosion resistance but also because of its very low thermal expansion coefficient. Expensive procedures to compensate thermal expansions are not needed. The most important physical properties are listed below (see DIN ISO 3585) Middle linear thermal coefficient of expansion α 20/300 = ( ) x 10-6 K -1 Middle thermal conductivity between 20 and 200 C λ 20/200 = 1.2 W m -1 K -1 Middle specific heat capacity between 20 and 100 C C -1 p 20/100 = 0.8 kj kg K -1 Middle specific heat capacity between 20 and 200 C C -1 p 20/200 = 0.9 kj kg K -1 Density at 20 C p = 2.23 kg dm -3 Mechanical properties The permissible tensile strength of Borosilicate glass 3.3 includes a safety factor which takes into account practical experience on behaviour of glass and, in particular, the fact that it is a brittle material. It is not able to equalise stresses occurring at local irregularities or flaws, as happen in the case of ductile materials such as metals. The safety factor also takes in account additional processing of components (ground sealing surface), handling of the glass (minute surface damage) and permissible pressures and temperatures to which it may be subjected in use. The design figures indicated below and specified in EN 1595 therefore apply to permissible tensile, bending and compressive stress to which glass components may be subjected taking into account the likely surface condition of glass in service. Strength parameters Tensile and bending strength K/S = 7 N mm -2 Compressive strength K/S = 100 N mm -2 Modulus of elasticity E = 64 kn mm -2 Poisson's ratio (transverse concentration figure) ν = 0.2 3

13 TECHNICAL INFORMATION Optical properties The transmission of UV light, which has a great importance for photo-chemical reactions, lies in the middle spectrum somewhat higher than that of normal window glass. Should light-sensitive substances be processed, so the use of brown coated Borosilicate glass 3.3 is recommended. This permanent coat reduces the UV light transmission to a minimum. PERMISSIBLE OPERATING CONDITIONS Components and apparatus are not only employed at room temperature and normal pressure, but also under vacuum, slight overpressure and/or at higher temperatures causing stresses at the tube walls. To balance these stresses, the wall thickness must have a certain size which must not fall below. Due to the given wall thickness, the allowed operating conditions regarding operation pressure and operation temperature need to be limited. Permissible operating temperature Borosilicate glass 3.3 only deforms at temperatures which approach its transformation temperature (approx. 525 C) and up to this point it retains its mechanical strength. The permissible operation temperature is considerably lower - normally around 200 C- for glass components, provided that there is no sudden temperature shock. At sub-zero temperatures tensile strength tends to increase. Therefore, Borosilicate glass 3.3 ca be safely used at temperatures as low as -80 C. Thermal shock Rapid changes in temperature across the walls of glass components should be avoided during operation. They result in increased thermal stress in the glass which has an adverse effect on the permissible operating pressure of the components. Although it is not possible to give a definite figure applicable to all the operating conditions which occur in practice. A maximum permissible thermal shock of 120 C can be taken as a general guide. Permissible operating overpressures Glass components in all nominal sizes that are basically cylindrical, domed and spherical can be used with full vacuum (-0.1 bar), provided they are not specially marked otherwise. The permissible temperature difference between internal (product side) and external side is 180 C, provided otherwise is not marked. 4

14 TECHNICAL INFORMATION TUBE ENDS All tube ends, exceptions not considered, are preferably connected with ground joints (conical or spherical) or with laboratory flanges. Should be required additional special connecting elements (e. g. clamps), please see the corresponding pages in catalogue part "Semi-finished products" chapter 3. For laboratory flat flanges, especially used for reaction vessels, we offer a connecting piece that is both support and connection. Safety flat flanges are used as connectors to temper jackets. The corresponding flange connections are described in catalogue part "Semi-finished products" chapter 3. Threaded tube ends, preferably in type GL, are used when hoses are employed for feeding or draining the product or when measuring units are necessary. Test tubes and bottles are also available with thread. The mentioned exceptions are high vacuum flanges in catalogue part "Semi-finished products" chapter 3 and the Rotulex connecting system, described in the same chapter. If other usual flanges for glassware are required, they will be also available. All important dimensions of ground joints, laboratory and safety flat flanges and GL-threads are listed in the table below.

17 TECHNICAL INFORMATION DOUBLE JACKET GLASS COMPONENTS Double jackets fulfil several purposes in thermal processing. They serve either for heating or cooling of the product during the process or they have an insulating function. Provided it is possible regarding to the construction, both sides of the double jacket are sealed. The different expansion of inner and outer cylinder during the operation is compensated by internal bellows (see pict. 4) Components with ground tube ends have an integrated socket or ground cup in the double jacket. Sockets or ground cups are integrated in the double jacket if the components have ground tube ends. Cone and ground ball are not integrated in small nominal sizes. Components which are fitted with a safety flat flange at product side allow a double jacket design up to the tightness area. You will find double jacket components in the appropriate chapter of this catalogue. Temper jackets When the connections of the temper jacket are fitted with safety flat flanges, olives as connectors are available. Insulating jacket Different components for the laboratory technique (e.g. columns) are available with special insulating jackets. In this case, the inner side of the jacket is silver coated and the jacket space itself is evacuated (10-6 mbar). The loss of heat is reduced to a minimum. Design of the jacket see pict. 4. Permissible operating conditions The permissible operating overpressures mentioned at page 4 are also valid for the inner parts of double jackets. Due to the construction, there are divergences regarding to the permissible operating temperature in the inner component and the permissible operating conditions in the jacket. Permissible operating temperature For temper jackets consisting of one part and sealed on both sides, the permissible operating temperature in the jacket must not exceed 200 C. The maximum permissible temperature difference between jacket temperature and ambient temperature should not be more than 180 C. The product temperature should not be higher than 50 C as the product temperature. Permissible operating overpressure For temper jackets consisting of one part and sealed at both sides, the permissible overpressure is -1 to +0.1 bar.

18 TECHNICAL INFORMATION SPECIAL MATERIALS In some cases, other materials than Borosilicate glass 3.3 are used for components in laboratory technique e.g. PTFE or metallic materials. - We are widely experienced in this area, so that it will not be a problem to meet the specific requirements. PTFE The function of the component made of PTFE decides, what type of PTFE will be used: pure PTFE, modified PTFE, glass fibre reinforced or coal fibre reinforced PTFE. Process technical reasons are also a decisive factor. What type of material is used, see the description of the respective component. Other synthetic material Besides PTFE, other synthetic materials are used in laboratory technique, e.g. silicone rubber. Metallic material The range of usable metallic materials is large and reaches from chrome-nickel steel, enamel steel to titan, Tantalus or Hastelloy. The required corrosion resistance defines the choice of the material. Information about the specific properties of the materials you will receive on request. Further materials In special cases, we also use other materials like graphite, ceramics etc. Construction and process relevant reasons define together with the special requirements of the customer the type of these materials. Due to our experiences with those corrosion resistant materials we have a wide know how in this area and so we are able to advise you on this. 9

44 STOPCOCKS/VALVES STOPCOCKS AND STOPCOCKS WITH SIDE ARMS FOR MANIPULATORS Not only our connecting pieces with spherical ground joint (see chapter 3) but also our stopcocks with arms, made of Borosilicate glass 3.3, distinguish by the high precession of manufacture and the top surface quality. Barrel and hollow glass key of the stopcock are interchangeable. The keeping of the sharp tolerance limits regarding to the angles, mantle line and diameter of the cone leads to a large touching area from barrel and cone. The result is a high vacuum tightness with minimal surface pressure. Some types of stopcocks are delivered with PTFE or full glass key. Full glass keys are recommended for use at high temperatures. A retaining device at the key prevents inadvertent removal and gives additional safety for operations under slight overpressure. In this point, the stopcocks fully meet the requirements of DIN , part 1. On request, other nominal sizes as described in our standard delivery range are available as well as special designs, e.g. stopcocks in nominal size 3 with bore diameter of 2 or 3 mm. All stopcocks described below meet the conditions for interchangeability of DIN , part 1. Due to this fact, the addition "NS" in the catalogue number is not necessary. On the product itself, NS is indicated. The described quality features are only maintain, when the keys are never turned dry in the barrel. As lubricating substance we recommend the media itself, pastes with PTFE or grease. The substances must be thin applied on the key, and then the key must be turned with slight pressure. PTFE coated hollow glass keys are available as an alternative for an additional charge. Lubrication is not required for these keys.

52 STOPCOCKS/VALVES VALVES WITH ARMS FOR MANIPULATORS Besides stopcocks, valves are the most employed locking devices in laboratory technique. Because of their various use, they have to fulfil many jobs. These jobs reach from simple locking of a liquid at normal pressure to use at high vacuum. This variety of applications has not only led to a wide range of designs, but also to spindle valves with higher or lower quality standard with the same cost/performance ratio. So the user has the possibility to choose lower price locking devices for simple purposes. All designs and types have an utmost universal corrosion resistance, because the media can only get in touch with Borosilicate glass 3.3 (valve body) and PTFE (spindle). Additional, all types are fitted with a key locking device, what prevents complete unscrewing of the spindle out of the valve body. The appropriate requirements for safety in laboratory are fully met. HIGH VACUUM - SPINDLE VALVES All these products of highest quality standard distinguish by the very robust construction and minimal leakage rate. O-rings, fitted in the valve stamp and with adjustable pressing power, guarantee an excellent sealing between spindle and body. This and the metal cone in the spindle ensure a perfect guiding of the valve insert. Therefore, high vacuum spindle valves cover the whole range of requirements for use in laboratory, reaching from use at high vacuum to on/off functions for liquids at normal pressure. The only use of these valve can reduce the costs of storage. The valve throttles in all designs are made of glass fibre reinforced Polyamide and is so sufficient corrosion resistant. Special designs are available on request. High vacuum spindle valves can be used up to a temperature of 230 C. But we recommend the use of Rulon valve stamps for temperatures higher than 180 C. The glass body and the upper part of the valve for all designs without and with tempering jacket (which have a longer spindle) are interchangeable. They can be ordered as single components. 4.10

81 VESSELS/ACCESSORY STIRRER SEALS Stirrer serve for mixing of liquids with solid, liquid or gaseous solids i.e. for dissolving, reaction, emulsifying, distributing, precipitating, heating, cooling etc. The processes can run at the same time or one after the other and can set in run or speeded up by stirring. In distilling bulbs are not only stirred for a better heat exchange but also to avoid delay in boiling or over-heating. Following are listed different designs of seals and stirrers for various stirring tasks. The sealing of the glass stirrer is effected with KPG (= Kalibrierte Präzisions Glasrohre = calibrated precision glass tubes) or COMBINORM stirrer seals which are suitable for normal pressure, or with vacuum magnet stirrer seals.

Even in fine vacuum they can be employed without use of a boiling capillary or boiling stones. Vacuum stirrer seals can also be employed for stirring under exclusion of the outside atmosphere, at pressure fluctuations or for working with air or moisture sensitive substances. Magnet stirrer seals, made of Borosilicate glass 3.3 The power transmission on the shaft is effected via a relative strong fourfold polarised Oersted magnet coupling. The inner magnet is enwrapped in PTFE, the outer one guided counter magnet is connected via a flexible coupling with the stirrer drive.

This means, that first the coil is flowed through by the tempering media and then the jacket. Other connecting arms at the tempering jacket are available on request. Condensers, Liebig Liebig condensers are manufactured according to DIN Liebig condensers according to West have a simple design with cylindrical shape. The vapour line is narrow sealed onto the jacket. These condensers can be used in oblique and vertical fitting.

91 HEAT EXCHANGER Allihn condenser Bulb condenser (outside condenser) are manufactured according to DIN as far as they are part of this standard. The inner surface is greater than those of simple condensers.

92 HEAT EXCHANGER Coil condensers These coil condensers are an enhanced model due to the coil arrangement of the vapour tube. The surface area is considerably greater than corresponding Liebig condenser. The inner coil has a relative small diameter, so that the vapour passage will be increased and the time for the heat exchange from the vapour to the cooling water is short.

97 DISTILLATION/ACCESSORY GENERAL The distillation process is one of the most employed separating applications in laboratory, technique and production. It is used for material mixtures, which have concentration differences in the thermal balance between the vapour and liquid phase. The efficiency is decisively determined by the speed of the material and heat exchange from one phase into another. There are two types of distillation 1. The ordinary distillation or direct flow distillation: The separation of the liquid mixture, charged with a component, and their subsequent condensation. This distillation is successful for mixtures, whose components have boiling points which differ by at least Rectification or reverse flow distillation: Parts of the condensate are guided back to the boiling mixture in reflux flow to the rising vapour. The hereby forced material and heat exchange between the rising vapour and the reflux condensate increases the separation multiply. The effect is as higher as more intensive the two phases are in contact. Different component parts in the column enable this effect. The separation is successful for mixtures whose components have boiling points which differ by at least 0.5. The size of the column depends on the separating task. The diameter of the column is defined by the throughput and the strain of the column, while the height is defined by the required product purity. The un-controlled condensation at the walls is reduced to a minimum by insulation of the column with silver coated vacuum jackets (10-6 mbar) to reach a constant strain over the whole column length. The vacuum jacket has sight strips and bellows (one bellow/ 500 mm length). The column type and its packing, which have also an influence on the column size, are chosen corresponding to the mixture to separate. Also costs, maximum permissible process temperature and operating pressure, corrosion resistance and contamination of the product decide about the column type. The columns can be supplied with measuring connection on request. The column heads -vapour divider and liquid divider- are available in numerous variants, manually or automatically controlled. Older manually controlled column heads have stopcocks as locking devices with all its known disadvantages: touching with grease, not tight towards outside, especially under vacuum operations, difficult to adjust because the reflux ratio is unknown and depending from stress. Glass needle valves provide a substantial better reproducibility of the adjustment but throughput fluctuations with changing of the viscosity are also appear. Really constant, reproducible reflux ratios which are also independent from strain, viscosity and surface stress can only be reached with electromagnetic controlled vapour dividers and liquid dividers. Column heads with electromagnetic control lead the product stream which exhausts at the upper end of the column in pre-chosen time intervals of same or different length as reflux back into the column or as distillate into the receiver. Thereby can be separated either the vapour or the liquid. The separation of the vapour is recommended when in condensations two liquid phases or light volatile substances arise. In other cases, the separation of the liquid is appropriate. 7.2

98 DISTILLATION/ACCESSORY PACKED COLUMNS These columns can be suited to the respective separating problem in an easy way by choosing of the right packings as inlays for increasing the substance exchange. Therefore, they can be universally employed. The columns have a collecting cage in the lower part which has a low loss of pressure and that serves together with some bigger packings as pad for the column packing. All columns are delivered with evacuated (10-6 mbar) silver coated insulating jacket, sight strips and outer bellows (one bellow packing per 500 mm length). Columns with bellows inside, bigger nominal sizes and in special lengths are available on request. On request all columns are available with measuring connection GL 18. If this connection shall be sealed between basic ground joint and collecting cage, the column will be approx. 50 mm longer. Packings do not belong to the delivery.

On request we supply also packings in other sizes and types for special applications. Wire mesh rings made of stainless steel in design A provide a high separating efficiency and a low loss of pressure. A disadvantage is the low corrosion resistance. Wilsonspirals made of Borosilicate glass 3.3 in design B provide a higher corrosion resistance but have a lower separating efficiency and a higher loss of pressure. Corrosion resistant Raschig rings, also made of Borosilicate glass 3.3 in design C, provide the lowest separating efficiency and higher loss of pressure.

103 DISTILLATION/ACCESSORY BUBBLE CAP TRAY COLUMNS They have a constant high efficiency over a wide range of loading. Bubble cap tray columns (also with nominal size DN 30) are especially interesting for analysis, whose results will be later translated into a larger dimension. Also the separating efficiency per column length is relative high. Due to the relative high loss of pressure and operating volume, these columns are only used for pressures higher than 50 mbar and for larger substance volumes. Since in bubble cap tray columns a good heat transfer is reached due to the high operating pressure and the constant high efficiency, this column is also available without silver coated high vacuum jacket. All jacketed columns are delivered with evacuated (10-6 mbar) silver coated insulating jacket, sight strips and outer bellows (one bellow packing per 500 mm length).

105 DISTILLATION/ACCESSORY LIQUID DIVIDER MANUAL OPERATED These column heads with integrated condensers serve for the adjustment of the reflux ratio of distillation columns, i.e. the separation of the arising condensate in reflux and drain, manual operated. When the valve which is located in the drain tube is fully opened, the separator is adjusted for total distillation drain since the reflux tube is sealed higher than the drain tube. The reflux ratio can be changed infinitely variable up to total reflux by turning the valve. If two valves are in the drain tube, one valve will only serve for on/off function. Manual operated liquid dividers are suitable, subject to design, for operations under vacuum and/or normal pressure. The used glass needle valves permit a fine adjustment and working under exclusion of air and/or moisture. Measuring connections are delivered with GL 18 but on request also available with standard ground joint NS 14/23. Cooling water connections: glass thread GL 14 complete with threaded hose connection GL 14. The use of an electronical operated liquid divider is recommended when the reflux ratio need to be exactly adjusted and shall be reproducible (see page 7.14). Manual operated liquid divider with spherical joints are also available in mm-size.

109 DISTILLATION/ACCESSORY LIQUID DIVIDER ELECTROMAGNETIC OPERATED We recommend the use of an electromagnetic operated liquid divider together with a timer (see chap. 10 "Measurement and control") when the reflux ratio need to be exactly and reproducible adjusted. In this variant, the swinging funnel with sealed counter magnet is attracted (total drain) or repelled (total reflux) from a magnet fastened outside of the column. The polarity of this magnet can be reversed with a timer. To guarantee an optimal function of the liquid divider, the time in which the funnel stays in one of its end points should not be shorter than two seconds. Electromagnetic controlled liquid dividers are suitable for operations under vacuum and normal pressure. The distillate outlet tube with tempering jacket allows the treatment of light volatile and high melting substances. A glass needle valve GNV 8 serves as locking valve. Spindle valves in size SPV 10 as locking valve and in size SPV 6 as ventilation valve are used in the vacuum frame. Electromagnet and timer please order separately.

111 DISTILLATION/ACCESSORY VAPOUR DIVIDER ELECTROMAGNETIC OPERATED Vapour dividers are recommended for difficult separations as are low temperature distillation, working with light volatile substances or two-phase azeotropes to adjust exactly reproducible reflux ratios. Furthermore, they are used instead of a liquid divider when the product flow is very small and the separation of the condensate does not lead to the required accuracy. While in the majority of the application purposes the standard design provides optimal results. For distillations of highly viscous and/or light crystallising substances, vapour dividers in special designs are used. Due to the special designed drain tube, they allow a fine tempering of the product to drain into the receiver. In both cases, the product stream is separated with an electromagnetic operated valve GNV 8, directed either to the reflux tube or to the drain tube and condenses there. The valve is operated with a timer and an electromagnet. Is the electromagnet without supply the reflux is free. With supply the magnet sealed in the valve spindle is attracted and the drain is open. All vapour dividers are only delivered with silver coated high vacuum insulating jacket (10-6 mbar), corresponding to their special tasks. Electromagnet and timer please order separately.

116 DISTILLATION/ACCESSORY HETERO-AZEOTROPE COLUMN ADAPTER To withdrawal either the specific light or heavy phase, depending on the task, these column heads are available in two different designs. Both heads work with an added agent which is filled in the phase divider up to overflow before starting the distillation. Its special feature is that it also works oneself at density fluctuations. The heads are set onto a column which has an evacuated (10-6 mbar) silver coated insulating jacket with sight strips and is fitted with a reflux condenser. During the distillation the arising vapour flows via the outer steam tube into the condenser and condenses. The distillate divides in a system of concentric tubes. One phase is led back as reflux to the column the other one is lateral drained. A tempering jacket around the divider can speed up the dividing process by heating or cooling. The inner dividing walls are so fitted, that they allow an automatic dividing without adjustment on the present density ratio. These devices also work trouble-free when the density ratios continuously change. The volume of the added agent keeps constant during the distillation since only the small part is brought out which is solved in the distillate. Also in steam distillations it is sufficient to give the required water volume into the boiling flask because the fluid phase is continuously in reflux. Large condensate volumes are not necessary since the azeotrope column adapter leads only the separated phase into the receiver. A small receiver flask can be used. Cooling water connections: Glass thread GL 14 complete with threaded hose connection GL 14 For withdrawal of the specific light phase These column heads are suitable for density ratios from light to heavy phase of 0.60 : 1 up to 0.95 : 1.

124 DISTILLATION/ACCESSORY Short path claisen links Caisen links, with sealed vacuum arm, are mechanically very stable. The condenser is streched up to the dropping lip of the condensate drain joint. An optimal distillate cooling is reached and considerably increased through the inner cooling tube (the cooling efficiency of the condenser can be compared with a jacketed reflux condenser). The condensate drains without touching the joint grease. The vacuum arm is in such a way assembled that no condensate can run into the vacuum tube. This type of link is also very suitable for light crystallising substances since the cooling temperature can be so controlled with a circulating thermostat that the condensate is kept liquid until the draining into the receiver. Another feature of this construction is that both cooling water connections are located at the link rim and so they cannot get in touch with the heating. Other jacket lengths are available on request. Short path Claisen links have a double ventilation. The length L1 is the streched length of the tempering jacket.

132 8 FUNNELS NORMAG - LABORATORY GLASSWARE L 308 e.1

133 FUNNELS GENERAL For introduction of a solid or liquid media into continuously working glass apparatus, systems with graduations are used. Their design is mainly cylindrical to reach a linear graduation. On request conical or spherical variants are available. The simplest design of feeding systems for liquid media are dropping funnels which are available with or without pressure equalising tube. Pressure equalising tubes are necessary, when different pressures occur or could occur in closed systems during the operation above or below the liquid to be fed. Should dropping funnels alternatively be used for vacuum, a design has to be chosen where the equalising tube is fitted with a single way or three way stopcock for locking. The space above the liquid must be open towards the atmosphere. Since many processes as e.g. continuously working distillations or kinetic analysis need a constant dropping frequency over a longer period of time and at pressure variations, dropping funnels must be employed. The adjustment of the required feed volume is effected with an interchangeable spindle valve, fitted below the funnel, or with an adjustable glass needle valve, adjustable from the top. Addition funnels are delivered either with pressure equalising line with single way or three way stopcock or with "Mariott"-tube. The "Mariott"-tube connects the space above the liquid to feed with the atmosphere. For operations under vacuum a design with an additional single way stopcock must be chosen. Some of these addition funnels are fitted with a silver coated high vacuum insulating jacket permitting the use in low temperature ranges. Some addition funnels have a suspended level bulb surrounding the original vessel. In this way, a pressure equalising is ensured when fluctuating hydrostatic pressures occur in the apparatus and the dropping speed keeps at a constant level until the vessel is completely drained. Normally, the connections at the tempering jacket of the funnels described below are glass threads GL 14. On request other tube ends are available. Additional you will find in this section powder funnels, separating funnels and addition funnels for solids for manual or motor-driven operation. 8.2

134 FUNNELS Dropping funnels, for operation under normal pressure Design A: Without pressure equalising line is favourably used as feeding vessel.

138 FUNNELS Addition funnels, for solids This funnel permits the controlled introduction of dry and granular solids with an auger into a reaction vessel. The integrated pressure equalising line, lockable with an PTFE spindle valve, allows an operation both under vacuum and inert gas. The use of threaded connections guarantee an excellent tightness also under vacuum operation and avoids contact with grease. To avoid a sticking of the auger during operation with boiling solvents, the ground joint cone of the funnel is fitted with a cooling jacket in design B. For strong boiling solvents, a Liebig condenser must be fitted between the addition funnel for solids and the reaction flask in both designs.

148 LABORATORY ACCESSORY COLD TRAPS They are used to reach an increased vacuum throughout the condensing of volatile components in general vacuum distillation. Can also be used in high vacuum distillation and to avoid contamination of the pump oil. Cold traps are also indispensable for distillation of substances which boil under 100 C at normal pressure and when via the distillate drain is made up the balance. The media to be cooled flows forced guided, the way is twice as long as the height of the cold trap, and will be cooled at a relative big surface compared to the flow section. The loss of vacuum caused by the trap is minimally. Capacity H NS NS1 D Des.

149 LABORATORY ACCESSORY Cold trap systems They are used, e.g. for continuously distillation, to avoid a freezing of the falling tubes in water containing distillates and thereby caused trouble of the process. An easy exchange of the cold traps, which are fitted with spherical ground joints, is guaranteed through switching off the PTFE spindle valve under normal pressure as well as under vacuum. A pair wise arrangement is recommended, so the distillate drain not needing to be stopped. The individual parts of the cold trap are interchangeable with each other. The cold traps are delivered ready for use.

161 MEASUREMENT/CONTROL NORMAG Digital Output Regulator 1 The NORMAG Digital Output Regulator 1 serves for controlling of electric heating systems. The heating volume can be adjusted from 1 % up to 99 %. The control is ensured by impulse group control. The supply is switched in zero point of AC that no failure due to voltage or current peaks can arise. The cycle time is two seconds. A contact thermometer, with glass break protection according to DIN , can be connected as excess temperature protection or a temperature limit can be preset via the NORMAG Digital Limit Thermometer. This input can also be switched by another automation device (e.g. PLC). When the temperature limit has been reached the heating volume is switched off bipolarly to <Blockiert> (Blocked) (lockable tumbler switch). A red blinking warning light indicates when a temperature limit has been breached. When the switch is in position <Intermittierend> (Intermittent) (lockable tumbler switch) the heating volume is automatically switched on again after falling of the temperature below the preset limit. The exceed of the temperature limit is indicated with a red blinking lightemitting diode. A potential-free alternating contact for additional control is provided. The control relay is energised when the limit has been reached. The NORMAG Digital Output Regulator 1 is installed in a bench case. Catalogue No. ESR

163 MEASUREMENT/CONTROL NORMAG Digital Output Regulator 2 The NORMAG Digital Output Regulator 2 serves like the NORMAG Digital Output Regulator 1 for controlling of electrical heating systems. But it is additionally equipped with an integrated Digital Limit Value Thermometer for Pt 100-thermometer. The temperature measuring range lies between 0 C and +300 C with a measuring accuracy of ±0.2 C. The temperature range to be set lies between 0.0 C and C. A Pt 100-thermometer made of corrosion resistant Borosilicate glass 3.3 in 4-core switch serves as measuring sensor. The value of the measured temperature is digitally displayed. The heating volume can be digitally set between 1 % and 99 %. The regulation is made by impulse group control. The supply is switched in zero point of AC that no failure due to voltage or current peaks can arise. The cycle time is two seconds. The boiling limit is monitored by the limit temperature which is pre-set at a potentiometer. When the limit temperature has been reached the heating volume is switched off bipolarly to <Blockiert> (Blocked) (lockable tumbler switch). A red blinking warning light indicates when a temperature limit has been breached. When the switch is in position <Intermittierend> (Intermittent) (lockable tumbler switch) the heating volume is automatically switched on again after falling of the temperature below the pre-set limit.

165 MEASUREMENT/CONTROL NORMAG Digital Timer 1 The NORMAG Digital Timer 1 is an electronic impulse generator for adjustment of the reflux and drain ratio. The reflux time and drain time can be selected from 0.1 sec to 99.9 sec independent from each other. With a lockable tumbler switch is determined whether the electromagnet of a liquid divider or of a vapour divider is in control. In liquid dividers, the sealed-in permanent magnet of the swinging funnel is attracted during the drain time and is repelled during the reflux time by changing of the polarity. In vapour dividers, the sealed soft iron core in the tappet is attracted by switching on the magnet field in the magnet during the drain. The magnet field is reset by switching on "Reflux", the tappet falls down due to the gravity and closes the distillate drain. Two light-emitting diodes serve for control. The green LED indicates the drain time and the yellow LED indicates the reflux time. The boiling limit is monitored with a contact thermometer with glass and cable breakage protection according to DIN resp. with a limit temperature pre-set at a NORMAG Digital Limit Thermometer. A red blinking warning light indicates when a temperature limit has been breached. When the limit has been reached, the NORMAG Digital timer 1 switches automatically to reflux. A red light-emitting diode indicates optically the reaching of the pre-set boiling limit. The function will be re-established when the temperature at the contact thermometer resp. the NORMAG Digital Limit Thermometer has dropped below the pre-set temperature or the limit temperature has been set higher. The red light-emitting diode goes out. An additional input for switching to total reflux can be installed. A programmable controller (e.g. PLC) can be connected at this input.

181 MEASUREMENT/CONTROL NORMAG Digital Differential Pressure Regulator 2 The NORMAG Digital Differential Pressure Regulator 2 enables the measuring of the differential pressure and the control of the bulb heating in an easy and reliable way. Naturally, the differential pressure is "0" between the sump and head when starting the column apparatus and so a regulation of the bulb heating via the differential pressure is not possible. Therefore, an output regulator* is integrated in the NORMAG Digital Differential Pressure Regulator 2 as starting help which takes over the regulation of the sump heating by impulse group control until the differential pressure, pre-set at a value setter, has been reached. During the starting period the heating capacity can be digitally adjusted between 1 % and 99 % of the total heating capacity. When the pre-set differential pressure has been reached, the regulation of the capacity is taken over automatically from the integrated differential pressure regulator. The differential pressure sensor is separately installed in the unit. The device described on page 10.5 is suitable as differential pressure sensor. The measuring are digitally displayed in 4 ½ digits. The required value is pre-set by 4 digits. Although the NORMAG Digital Differential Pressure Regulator 2 has a two-point regulating behaviour, a good capacity control is reached due to the irregular and fast changing boiling process and the herewith connected slight differential pressure changes. A contact thermometer with glass and cable protection according to DIN can be connected as excess temperature protection as well as a NORMAG Digital Limit Value Thermometer where the temperature limit value can be pre-adjusted. When the limit temperature has been reached, the heating capacity will be totally switched off bipolarly. The exceed of the limit is indicated by a red blinking light-emitting diode. When the pre-set level is re-established again the limit value level can be quitted with the switch "Rückstellen" (Reset). A potential-free alternating contact for additional control instruments is provided at the control contact output.

185 MEASUREMENT/CONTROL NORMAG Niveaumat Level Watching The NORMAG Niveaumat level controller serves for monitoring of the liquid level in vessels. It can monitor a minimum or a maximum liquid level. As sensors serve either light rods made of quartz with opto-electronic sender and receiver which work in the infra-red range or photoelectric barriers working in the infra-red range or magnet swimmer with Reed-contact. Light rod sensors are described on page During the monitoring of the maximum (lockable tumbler switch) the via the capacity output connected unit will be switched off bipolarly when the liquid level exceeds the adjusted level. The green light-emitting diode <Heizung> (heating) goes out; the red blinking light-emitting diode <Alarm> (alarm) goes on. A potential-free alternating contact for additional control instruments is provided at the control contact output. During the monitoring of the minimum (lockable tumbler switch) the alarm is set when the liquid level falls under the adjusted level. When the lockable tumbler switch "Intermittierend/Blockiert" (Intermittent/Blocked) is in position <Blockiert> (blocked), the user will not be automatically switched on again, even when the pre-set level has been already reached again. The alarm will be only quitted by pressing the button <Rücksteller> (Reset) and the user will be switched on. In position <Intermittierend> (Intermittent) the user switches automatically on when the liquid level has been increased (minimum watching) or fallen (maximum watching) again.

199 MEASUREMENT/CONTROL DEVICES FOR THE CAPTURE OF MEASURINGS, THE "ALMEMO" SYSTEM The ALMEMO system ALMEMO measuring devices are devices which are produced by the company "Ahlborn Mess- und Regeltechnik GmbH". These devices are used by NORMAG LABOR- und PROZESSTECHNIK GmbH in its process-technical laboratory units for process watching, control, data capture and recording. The ALMEMO system is there used when measurements are taken, analysed and administrated in the frame of laboratory automation. What is the special of the ALMEMO system? For the connecting of the sensors the therefore developed and patented intelligent ALMEMO plugs are used. They contain a programmable data carrier <EEPROM> in which the parameters of the connected sensor are stored. All measuring instruments are recognised automatically and the function will be accordingly suited, so this sensor provides a high flexibility and convenience in use. All sensors, once programmed, are interchangeable without further adjustment. Connected at a measuring device not only the measuring range is transferred but also all measuring corrections, scales, dimensions and even the sensor type. The power supply of the sensor and the cold-junction compensation are also taken over by the plug. ALMEMO plug with EEPROM and 6 screw type terminals Special sensors are not necessary, utmost every sensor can be connected with 6 screw type terminals. Programmed plugs are available but the customer can programme all parameter either via the measuring device manually or via a serial interface per PC. A selective locking is provided to avoid not wanted changes. The interface electronic for analogue and digital interfaces at the outputs is not integrated in the measuring device but in the plug of the connecting cable. The type and the parameters are also red by a data carrier in the ALMEMO plug and the device accordingly configured. Analogue or digital interfaces can be changed also with different parameters and without any programming. The ALMEMO measuring device is fully programmed by the intelligent ALMEMO plug when connecting the sensors and interface cables, excepted the time control of the process. On the other hand all parameters can be changed if necessary; all data carriers inside the plug can be overwritten

200 MEASUREMENT/CONTROL On the basis of the intelligent ALMEMO plugs all ALMEMO measuring devices have remarkable common properties: m There is a wide range of sensors, detectors and signals which can be connected at every input of every measuring device per the patented ALMEMO plug system. No programming is necessary since all sensor data is stored in the plug and the measuring device will be automatically configured. m All devices have the same input switch for 60 measuring ranges, guaranteeing always the same measuring results. m All sensors can be calibrated, scaled and clearly named by the help of the sensor data store. Highest precision is reached with lowest costs and measuring faults are excluded. m The switching of the measuring points is done galvanic separated with absolute wear-free semiconductor relays. A continuous measuring point scanning with 10 measuring/second is possible without problems over a longer period of time. m Analogue and digital interfaces are not installed in the devices but in the plugs resp. connecting cables. The user can choose according to the requirements, between analogue outputs, different interfaces (RS 232, RS 422, RS 485; LWL, Current-Loop, Centronics, wireless), alarm signals or trigger inputs. It will be only use what is required and it can be used with all other ALMEMO devices. m All measuring devices can be addressed via an interface and can be networked. An integrated distributor allows an easy assembling of up to 100 devices with network cables and the measuring capture over only one computer interface. For greater distances are provided RS 422/485 driver and distributor. This system minimises the costs for devices and cables, and EMV problems. It responds quickly to every new task and can be extended. m The software protocol and the command scale are also the same for all devices. One terminal is sufficient to programme all parameters and to scan the measuring data. Suitable output formats for printer or spread sheet analysis can be provided. m The ALMEMO devices differ in the case (manual device, bench case, 19''-unit, switch panel device, transmitter), the number of inputs (1 to 250), display elements, output elements and operating elements and the power supply. ALMEMO Data logger with 9 measuring inputs ALMEMO A wide range of software is available for further treatment of measuring on the PC. The program AMR WinControl has been developed especially for data capture and further treatment with ALMEMO devices and permits the comfortable programming and operation of these devices. The captured data can be shown in diagrams, mathematical treated, stored, printed and exported to other programs

201 MEASUREMENT/CONTROL The 32-byte version allows the optimal use of the features of WINDOWS 95/98 and WINDOWS NT. The windows surface and the Online help guarantee a quick training and a safe working with the program.

207 APPARATUS ROTATION PERFORATOR Besides distillation and sublimation, crystallisation, filtration and purification by absorption, extraction is an important method of enrichment, separation and purification of solid and liquid substances. It makes use of differences in behaviour towards solvents without chemical reactions taking place. The basic principle of these extraction apparatus is that the solvent is continuously evaporated in a boiling flask, condenses in a reflux condenser and drops onto the material to be extracted. From there it returns to the boiling flask, charged with the extracted substances. Dissolved substances can also be selectively separated from liquids with suitable solvents. All liquid-liquid extractions are based on the premise that the solvents used are not miscible with one another or only to a negligible extent. It is important for the solvent droplets to be well distributed to ensure that the phases are in intimate contact; however, this contact is very incomplete in traditional perforators. Therefore, the circulation of the extraction solvent through the material to be extracted has to be repeated frequently, which takes a lot of time. The rotation perforator according to H. Ludwig has a rotating distributor in the extraction vessel which is driven through a magnetic coupling. The extraction solvent fed from the condenser to the distributor is forced by centrifugal force through small holes in the distributor ring as fine droplets into the liquid to be extracted, thus ensuring that solvent is well dispersed and thoroughly mixed with the liquid to be extracted. The fact that there is close contact between the extraction and the liquid to be extracted over an adequate dwell time produces optimum exchange of matter. Since the liquid to be extracted also rotates in the vessel, the finely dispersed substance does not reach the separator zone of the perforator until it has been in the liquid to be extracted for an extended dwell time and continuously returns to the boiling flask from which the solvent leaving the extracted substance is fed back to the extraction circuit by being evaporated again. Liquid-liquid extraction is performed much more quickly in the rotation perforators according to Ludwig than any other traditional equipment. All ground joints are also available in other standard sizes, e.g. US-standard. Rotation perforator according to Ludwig These rotation perforator are used for liquid-liquid extractions for specific light solvents.

211 APPARATUS CHROMATOGRAPHY COLUMNS The chromatography is an analytic and preparative technique for separation and purification of organic substances as well as inorganic and bio-chemical substances. It can be described as a separation technique, which is proceeded by differentiated moving of the solved substances under influence of a moving solvent. Transparent glass columns are used as separating columns to observe the separation. After filling the glass column with the adsorption media (e.g. aluminium oxide -Al 2 O 3 -) it is very important to fill the column evenly with the solvent to reach a successful separation; air bubbles and uneven feeding must be avoided. The flow rate must be watched and should not be to high (3 to 4 ml/min in a column of 40 cm). Chromatography columns are available in 3 basic forms. Basic form 01: four piercing for taking a glass wool pad Basic form 02: Filter disc, drain funnel shaped Basic form 03: Filter disc, drain with very small death volume The basic forms 01, 02, 03 are available in the following variables of porosity: Variable 04: Variable 05: Variable 06: Variable 07: Variable 08: Filter disc porosity D0 Filter disc porosity D1 Filter disc porosity D2 Filter disc porosity D3 Filter disc porosity D4 Variable 09: PTFE-spindle valve Variable 10: Beaded rim Variable 11: Conical ground joint socket NS 14/23 Variable 12: Conical ground joint socket NS 29/32 Variable 13: Single way stopcock Variable 15: Tempering jacket Variable 16: Drain tube, bent Variable 17: Drain capillary tube Variable 18: Drain tube, bent with glass thread GL 14 and PTFEsqeeze srewing for attachment of fine hoses Variable 19: Drain with NS-cone and vacuum connection Variable 21: Variable 22: Variable 23: Variable 24: Variable 25: Variable 26: Variable 27: Variable 28: Variable 29: Variable 30: Variable 31: Variable 32: Variable 33: Variable 34: Variable 35: Variable 36: Inner diameter 10 mm Inner diameter 15 mm Inner diameter 20 mm Inner diameter 25 mm Inner diameter 30 mm Inner diameter 40 mm Inner diameter 50 mm Inner diameter 60 mm Filling height 200 mm Filling height 300 mm Filling height 400 mm Filling height 600 mm Filling height 800 mm Filling height 1000 mm Filling height 1500 mm Filling height 2000 mm Other inner diameters and filling heights are available on request.

213 APPARATUS APPARATUS FOR SIMULTANEOUS STEAM DISTILLATION-EXTRACTION (COMPLETE) This apparatus is suitable for insulation of high boiling substances which are very low water soluble and with a relative big molecular weight in relation to water. For extractions solvents can be used, whose specific weight is higher than 1. Before starting the distillation in the both flasks, the U-shaped tube is filled via the inlet tube with water or, if the specific weight of the organic solvent is higher than 1, the tube is filled with the solvent. The flask, connected with the distilling tube, contains the liquid with the specific higher weight. Catalogue No. SAA

214 APPARATUS SOXHLET EXTRACTORS Soxhlet extractors have a siphon which fully drains the filled extraction thimble in intervals. Inside the common Soxhlet extractor takes place a partial heat up but it is negligible. When a substance in coldness in fractionating extractions is selectively soluble, must be cold extracted. For this case, the Soxhlet cold extractor will be fitted with a cooling jacket. For extractions at higher temperatures, the Soxhlet heat extractor is used. The extraction thimble is heated with the vapour and drained with a siphon in intervals. The apparatus are fitted with jacketed condensers. The effectiveness of these condensers provides a high operating standard. A drying tube can be assembled on the upper part of the condenser.

219 APPARATUS APPARATUS FOR EXTRACTIVE STEAM DISTILLATION (COMPLETE) This apparatus is particularly suitable for exact determination of the content of ethereal oils in plant parts. Oils, extracted from the plant parts (buds, flowers, blossoms, fruits, seeds, leafs, twigs, herbs, bark, timbers, roots, nodules, bulbs) are differentiated in fad oils and ethereal oils. The ethereal oils are complicated mixtures of alcohol, aldehydes, ketones, ester, oxides, lactose, sulfurous and nitrogenous connections, terpenes and other still unknown connections. For determination of the content of ethereal oils in plant parts, the apparatus for extractive steam distillation has proved worthwhile in practice. The ethereal oil is extracted out of the precise weight-in substance in the extraction vessel with steam, condenses at the descending condenser and is separated from the water in the measuring tube. Ethereal oils with density lower or bigger than 1 can be exactly captured. A solution of the water soluble parts of the distilled oil is avoided through storage of a saturated sodium bromide solution in the measuring tube of the apparatus. The water flows back in the boiling flask over a reflux pipe which is lockable with a glass needle valve and the water will be further used for extraction process. The distillation time takes approx. 3 hours from the beginning of the boiling. The capacity of the extracted oil is exactly determined in the measuring tube. The percentage weight proportion of ethereal oils is ascertained through the determination of the density of the extracted oil with the help of a precision weighing pipette according to Pregl, a special pycnometer for density determination of little volumes. 100 x determined density x oil volume [ml] Extract weight of contents [g] = % ethereal oil Since the results of ethereal oils can enormously differ in subject to the used substance, the apparatus are available with measuring tubes in different sizes (0.8, 4 and 10 ml).

221 APPARATUS WATER SEPARATOR (COMPLETE) Water separator serve for continuous elimination of water, also in bigger concentrations out of organic liquids for drying, changing of the chemical balance. This separation is mainly reached by distillation with a tow medium. The condensate, draining from the reflux condenser, separates in two phases in the water separator which is usually equipped with a column. To ease this phase separation, the separating vessel is surrounded with a cooling medium. The progress of chemical reactions, which are run under water formation, can be observed with the volume of the separated water. The continuous elimination of water out of the reaction balance causes in such cases a considerably shorted reaction time and the result can be increased e.g. in condensation, acetalisation and esterification.

222 APPARATUS FLUORINE DETERMINATION APPARATUS (COMPLETE) With this fluorine determination apparatus, a quick determination of fluorine is possible within approx. one hour. After filling of the sample flask with the fine ground sample it is poured over with a mixture from silicic acid and phosphoric acid (but not to much to avoid a bubble over). The lying evaporator with horizontal heating rod and filled with water ensures a continuous boiling and a calm continuous vapour flow, which is heated in the vapour super heater at 250 C. The liquid volume keeps at the same level in the sample flask at this high temperature and so the flask need not to be heated. During the distillation, the horizontal heating rod must be covered with enough water, which can be dropped in. The vapour temperature and so the distillation speed keeps utmost constant. The arisen SiF 4 (silicon fluoride) escapes via the coil condenser a d can be titrated with Thiocyanat according to Volhard. This apparatus is delivered with frame and supports.

223 APPARATUS GAS PURIFICATION APPARATUS (COMPLETE) This gas purification unit for nitrogen and rare gas is completely equipped with manifold distributor. Chemical reactions with light and moisture sensitive substances e.g. free radicals and numerous organo-metallic compounds are proceeded with inert gas. Gases obtained commercially, e.g. nitrogen or preferably argon are sufficient pure for many purposes and can directly be used from the bottle. But for experiments with hyper-sensitive substances, even purified nitrogen needs a further purification to eliminate the in very low concentration existing contamination of oxygen, moisture, carbon dioxide and others. Important is, that the subsequent cleaning is proceeded just before the operation run to keep the risk of contamination or non-tightness through the long tube and hose lines as low as possible. The Normag gas purification apparatus has proved very worthwhile for fine purification of nitrogen and rare gas. Delivered with a moveable table rack frame

225 APPARATUS CYCLISATION APPARATUS (COMPLETE) according to Prof. Dr. Schill and Dr. Neubauer Apparatus for simple dilution and continuous feed of test solutions, suitable for carrying out of one component dilution principle reactions. Principle: A substance dropping out of a funnel becomes strongly diluted through reflux condensate before the substance drains with a continuous flow into the reaction vessel. Application and features: In chemical reactions the yield often depends on the concentration of the component to be fed. Useable results are only reached under high dilutions, especially in cyclisation. It is necessary to avoid single droplets and to ensure a continuous feeding of the reaction solvent. Local over-heating are avoided. A single neck flask is sufficient as reaction flask since all other functions -dropping in, dilution, continuous feeding, stirring, cooling, pressure equalising, are taken over from the cyclisation inset. Due to the permanent liquid circulation, solvent is saved. The test solution can be dropped in as concentrated solvent. The volume of the solvent in the reaction flask will not be increased and so the flask need not to be chosen bigger. Higher results can be reached by avoiding of local larger gradients of concentration. The standard dimensions, guaranteed by series production, ensure reproducible and comparable results. Hardly soluble substances which can only dropped in under heating, are solved in the hot reflux solvent concentrate. Comment: Since the dropping in of a component in cyclisation often lasts over a longer period of time, a great importance has been attached to the safe operating of the stirrer. As one can see in the picture, the stirrer shaft is guided through the cyclisation knee and the jacketed reflux condenser. As guiding for the stirrer shaft serve two PTFE sockets. The lower guide if the shaft is continuously lubricated and cooled by the reflux condensate. The rising vapours flows through four openings into the cyclisation knee and through the edge into the jacketed reflux condenser. The condensate runs over the walls, is sampled in the edge and is guided to the side arm of the knee which is made as a siphon. The substance fed over a addition funnel flows through a narrowing to the liquid which is dammed in the knee, is solvered there and strongly diluted by the reflux condensate. The reaction media comes through the four openings into the flask directly in the suction of the stirrer, the place of the most intensive distribution. A liquid holdup cannot occur during normal operation. The total cross-section of the four openings (400 mm²) is chosen larger as the cross-section of the a conical gound joint NS 29/32 (350 mm²). The thread connections of the jacketed reflux condenser for inlet and outlet of the cooling water are located at the back of the cyclisation apparatus. The side arm with NS 14/23 is located in front. It can serve for accommodation of a drying tube. The pressure equalising is also proceeded via this side arm.

231 UNITS LABORATORY UNIT FOR GAS ABSORPTION GENERAL Absorption is the intake of gases in a washing liquid by physical solving or reversible chemical reaction. Depending on whether the gas by physical solving or by chemical binding is bound it is a physical or a chemical absorption. When a mixture CO 2 /air gets in touch with water, the CO 2 gas is absorbed in the water but the air is not solved. The absorption capacity of the water for carbon dioxide depends on the influence time, the pressure and the temperature. This unit provides the facility the carbon dioxide to wash out of the carbon dioxide/air mixture. Due to the ratio of the both components determining the separating effect, the solvent flow and the gas flow are aimed varied. Pict. 1 Laboratory unit for gas absorption The unit offers the following advantages: m m m Due to the slight construction height, use in almost all laboratories is possible. All media-touching parts are made of Borosilicate glass 3.3 or PTFE. The single components of the unit are connected with standardised connectors. 12.3

232 UNITS Construction of the Laboratory unit for gas absorption The core of the unit is the absorption column consisting of the absorption tube (K), a gas inlet (G) and a siphon part (S). The mentioned parts are connected with conical ground joints NS 45/40 and fitted with a silver coated high vacuum jacket. The absorption column has an inner diameter DN 50 and a length of approx mm. The inlet component (E) seats on the upper end of the column and at the lower end seats the siphon part with the drain valve. The both gases air and CO 2 are introduced via the connections 1 and 2, adjusted with the valves (V2) and (V3) and mixed together in the mixer (M) then fed over the heat exchanger into the absorption column which is filled with Raschig rings 4/4 mm. The absorption liquid water is directed from the top towards the gas in counter flow from vessel (B1) with the pump (P) and over a flow meter (Q1) and the heat exchanger (W1). The both heat exchanger (W1) and (W2) are connected with a thermostat (TS). Through this is reached that absorption gas and absorption liquid are fed with the same temperature into the absorption column. The issued gas is directed for analysis into a gas analyser (GA). The inlet gas can be also analysed by switching of the three way stopcock (VD). Following data can be captured via a data logger in the unit: - Temperature at the water inlet (T1) - Temperature at the gas inlet (T2) - Temperature in the siphon (T3) - Electric conductivity at the water inlet (L1) - Electric conductivity in the siphon (L2) - Differential pressure above the column (DD) - Gas concentration (GA) The measuring can be analysed at the PC with a suitable software.

234 UNITS Construction of the absorption unit The core of this NORMAG unit for absorption of reaction gas is the absorption column which is sealed on the receiver for the absorption liquid. The absorption liquid is cooled by a double coil, made of Borosilicate glass 3.3, inside the absorption receiver. Connections for the cooling are flanges Pl 15 providing the facility to connect a thermostat hose. Two glass adapter for coupling flange Pl 15 and olive D11 are part of the delivery. The NORMAG glass pump for forced liquid circulation of the absorption liquid with magnet drive is located below the receiver, guaranteeing a quick exchange. Normally, the pump volume is 120 litres/h by 1500 revs/min, but the pump volume can be changed with the control device. Due to safety reasons, the suction and pressure tubes are inside the absorption column. To increase the reaction surface, Raschig rings as packing are used. The gas to be purified is introduced via the HV spindle valve 3 into the unit and rises in the absorption column. The pumped up absorption liquid runs over the Raschig rings towards the gas and the mass transfer can start. The drain off of the purified gas is effected by the connected manifold with spindle valves. The flange and thread connections at the receiver serve for the refilling of the absorption liquid and for taking a thermometer or ph-sensor. A connection, which serves for cleaning the unit is sealed on the head of the absorption column. The used absorption liquid can be drained off by opening the spindle valve at the pump, then the unit can be cleaned and after closing the valve a new absorption liquid can be introduced. For automatic use, an addition funnel is tightly connected with the receiver, so that the absorption liquid can be refilled automatically.
