So making long-term quality assurance for te associate instrumentation all te more important, from volumetric flasks to stoppers. From one ay to te next, wit eac analysis. Mae of DURAN borosilicate glass 3.3, our volumetric flasks, measuring an mixing cyliners, an burettes offer excellent cemical an termal resistance, someting tat is above all reflecte in te mecanical properties of te glassware. Tanks to exact processing an precisely calibrate scales, tey permit te igly accurate etermination an measurement of volumes. DURAN proucts are available in two accuracy classes: class A/AS an class B (see te Capter on Tecnical Information). Te two classes iffer in terms of volume tolerances, wit class A being te igest accuracy class an class B being approximately alf tat of class A. Class AS as te same tolerances as class A, but is esigne to permit a more rapi outflow. Volumetric glassware wic meets te requirements of te German weigts an measures regulations isplay te conformity marking DE-M. 03 Volumetric flasks an cyliners are calibrate to measure te exact amount of flui tey contain ( In ), i.e. up to te ring mark on te vessel. Tis allows, for example, te esire concentration to be set precisely. Pipettes an burettes are calibrate to measure te amount of flui elivere ( Ex ). Tis calibration takes into account surface aesion to te glass / capillary effects.

173 GLASSWARE FOR MICROBIOLOGY 07

174 GLASSWARE FOR MICROBIOLOGY Due to its ig termal-sock resistance, DURAN microbiology glassware is ieal for auto-claving an sterilisation processes an sows, even after multiple use no signs of wear. Unlike plastic items, it is very resistant to mecanical wear even after repeate use an sterilisation cycles. Due to te nearly inert beaviour, tere are no interactions (e.g. ion excange) between meium an glass an any spurious influence on experiments is tereby effectively exclue. DURAN proucts are completely transparent in visible ligt an unlike many plastic proucts are ieal for use uner te microscope. DUROPLAN Petri ises offer outstaning performance ue to teir istortion-free transparency an ig planarity (flatness). Tese excellent geometrical properties enable uniform agar istribution an reproucible culture growt. Alongsie te Petri ises, te DURAN range inclues a wie range of culture bottles, culture flasks, roller bottles an spot plates. In aition, tere are various types of staining ises. Usage tips: Only autoclave proucts tat are free from amage suc as scratces, cracks or nicks.

192 WHAT IS GLASS? Glass is an inorganic mixture fuse at ig temperature wic soliifies on cooling but oes not crystallize. Its basic components, network formers an moifiers, are present in te common glasses in te form of oxies. Typical glass formers (network formers) are silicon ioxie (SiO 2 ), boron trioxie (B 2 O 3 ), posporus pentoxie (P 2 O 5 ) an aluminium oxie (Al 2 O 3 ). Tese substances are capable of absorbing (issolving) metal oxies up to a certain proportion witout losing teir glassy caracter. Tis means tat te incorporate oxies are not involve in te formation of te glass but moify certain pysical properties of te structure of te glass as network moifiers. A large number of cemical substances ave te property tat tey soliify from te molten state into a glassy state. Te formation of glass epens on its cooling rate an a necessary prerequisite is te existence of mixe types of bon (covalent bons an ionic bons) between te atoms or groups of atoms. As a result, glass-forming proucts sow a strong tenency wilst still in te molten state towars amorpous tree-imensional networking toug polymerisation. Crystals are forme wen te iniviual atoms form a regular tree-imensional arrangement in wat is known as a crystal lattice as soon as te particular substance canges from te liqui to te soli state. Glass, owever, forms a largely amorpous network wen it cools own from te molten state. Te components mainly involve in te formation of te glass are terefore escribe as network formers. Te glass-forming molecules in tis network can incorporate ions tat open up te network at certain points, canging its structure an tus te properties of te glass. Tey are terefore calle network moifiers. WHAT IS DURAN? Te special features of DURAN Very ig cemical resistance, nearly inert beaviour, a ig usage temperature, minimal termal expansion an te resultant ig resistance to termal sock are its most significant properties. Tis optimum pysical an cemical performance makes DURAN te ieal material for use in te laboratory an for te manufacture of cemical apparatus use in large-scale inustrial plant. It is also wiely use on an inustrial scale in all oter application areas in wic extreme eat resistance, resistance to termal sock, mecanical strengt an exceptional cemical resistance are require. Cemical composition of DURAN 08 DURAN as te following approximate composition: 81 % by weigt SiO 2 13 % by weigt B 2 O 3 4 % by weigt Na 2 O / K 2 O 2 % by weigt Al 2 O 3 DURAN properties are specifie in DIN ISO 3585.In contrast to oter borosilicate 3.3 glasses, DURAN is notable for its igly consistent, tecnically reproucible quality. 192

193 08 TECHNICAL INFORMATION PRODUCT SECTION Cemical properties Te cemical resistance especially of DURAN glass is more compreensive tan tat of all oter known materials. DURAN borosilicate glass is igly resistant to water, acis, saline solutions, organic substances an also alogens suc as clorine an bromine. Its resistance to alkali is also relatively goo. Only yrofluoric aci, boiling posporic aci an strong alkalis cause appreciable surface removal of te glass (glass corrosion) at elevate temperatures (> 100 C). Due to te nearly inert beaviour, tere are no interactions (e.g. ion excange) between meium an glass an any spurious influence on experiments is tereby effectively exclue. Hyrolytic resistance DURAN correspons to Class 1 of te glasses tat are ivie into a total of 5 yrolytic resistance classes in accorance wit ISO 719 (98 C). Te amount of Na 2 O/g glass grain leace out after 1 our in water at 98 C is measure. For DURAN te quantity of Na 2 O leace out is less tan 31 μg/g of glass grain. DURAN also correspons to Class 1 of te glasses ivie into a total of 3 yrolytic resistance classes in accorance wit ISO 720: (121 C). Te quantity of Na 2 O leace out after 1 our in water at 121 C is less tan 62 μg/g of glass grain. Due to its goo yrolytic resistance, DURAN meets te requirements of te USP, JP an EP for a neutral glass tat correspons to glass type 1. It can terefore be use in an almost unrestricte way in parmaceutical applications an in contact wit foostuffs. Hyrolytic attack on DURAN as a function of time () Aci resistance DURAN correspons to Class 1 of te glasses ivie into 4 aci classes in accorance wit DIN As te surface removal after boiling for 6 ours in normal HCl is less tan 0.7 mg/100 cm 2, DURAN is classe as aci-resistant borosilicate glass. Te quantity of alkaline metal oxies leace out in accorance wit ISO 1776 is less tan 100 μg Na 2 O/100 cm 2. Aci attack on DURAN as a function of aci concentration 193

195 08 TECHNICAL INFORMATION PRODUCT SECTION Pysical properties Temperature resistance wen eate an termal sock resistance Te maximum temperature for sort-term use for DURAN is 500 C. Above a temperature of 525 C te glass begins to soften an above a temperature of 860 C it canges to te liqui state. As it as a very low coefficient of linear expansion (α = 3.3 x 10 6 K 1 ), a feature of DURAN is its ig termal sock resistance up to ΔT = 100 K. For a temperature cange of 1 K, te glass canges by only 3.3 x 10 6 relative lengt units, resulting in low levels of mecanical strain were a termal graient exists. Te termal sock resistance is influence wall tickness an prouct geometry. Temperature resistance at low temperatures DURAN can be coole own to te maximum possible negative temperature an is terefore suitable for use wit liqui nitrogen (approx. 196 C). During use / freezing special attention soul be given to te expansion of te content. In general DURAN proucts are recommene for use own to 70 C. Wen working at low temperatures, te effect of any expansion of a DURAN vessel s content must be borne in min. During cooling an tawing ensure tat te temperature ifference oes not excee 100 K. In practice, terefore, stepwise cooling an eating are recommene. Wen freezing substances in suc items as DURAN bottles or DURAN test tubes, te container soul only be fille to a maximum of 3/4 of its capacity. Moreover, it soul be frozen slante at an angle of 45 (to enlarge te surface area). Te minimum service temperature is epenant upon te properties of any screw caps or oter components use. For te blue PP screw cap te minimum temperature is 40 C. Use in te microwave DURAN laboratory glassware is suitable for use in microwaves. Tis also applies to plastic coate DURAN proucts. Overview of te pysical properties of tecnical glasses Description Linear expansion coefficient α (20 C / 300 C) [ 10 6 K 1 ] Transformation temperature [ C ] Density [ g / cm 3 ] DURAN FIOLAX Soa-lime glass SBW Optical properties In te spectral range from about 310 to nm te absorption of DURAN is negligibly low. It is clear an colourless. Fairly large layer ticknesses (axial view troug pipes) appear sligtly yellow/greenis. Amber-coloure DURAN proucts are suite to use wit ligt-sensitive substances (see amber colouring of DURAN ). Tis results in strong absorption in te sort-wave region up to approx. 500 nm. In potocemical processes te ligt transmission of DURAN in te ultraviolet range is of particular importance. Te egree of ligt transmission in te UV range inicates te ease wit wic potocemical reactions can be carrie out, for example clorinations an sulfoclorination. Te clorine molecule absorbs ligt in te range from 280 to 400 nm an tus serves as a transmitter of te raiation energy. Amber colouring of DURAN laboratory glassware Amber colouring enables storage of ligt sensitive substances in DURAN proucts. Ligt transmission in te wavelengt range between 300 an 500 nm is, in comparison wit DURAN clear glass, < 10 %. Accoringly amber DURAN glass correspons to USP/EP specifications. 195

198 08 TECHNICAL INFORMATION PRODUCT SECTION CLEANING LABORATORY GLASSWARE Special glass laboratory apparatus can be wase by an in a soaking bat or by macine in a lab waser. Laboratory ealers can supply a wie range of etergents an cleaner-isinfectants for bot metos. As contamination uring te elivery of our laboratory glassware cannot be totally rule out, we recommen wasing laboratory glassware before it is use for te first time. To care properly for laboratory glassware, it soul be wase immeiately after use at low temperature, on a sort cycle an wit low alkalinity. Laboratory apparatus tat as come into contact wit infectious substances or microorganisms soul be treate in accorance wit te current guielines. Depenent on te substance, autoclaving (e.g. to kill microorganisms) may be necessary prior to cleaning, but it is generally recommene tat cleaning or wasing of glass proucts be carrie out prior to autoclaving or ot-air sterilisation. Tis prevents irt or impurities from aering to te glassware surfaces an prevent amage cause by any possibly aering cemicals. Manual cleaning Te generally recognize meto is to wipe an rub te glass wit a clot or sponge soake in cleaning solution. Abrasive cleaners an abrasive sponges soul not be use on laboratory glassware as tese can amage te surface of te glass. Surface amage can affect te glass properties an limit furter use of te prouct. Wen soaking glassware it soul generally be left in te cleaning solution for 20 to 30 minutes at room temperature, ten rinse wit tap water followe by istille water. To clean te glass as gently as possible, an tus exten its service life, a prolonge soaking time an iger temperature soul only be use for stubborn soiling. Laboratory glassware soul not be soake for long perios in strongly alkaline meia at more tan 70 C since tis can ave an averse effect on te ceramic printing an may cause glass corrosion. Also to be avoie is severe mecanical action, e.g. scraping using a metal spoon. Waser-isinfectors for automatic laboratory glassware reprocessing Waser-isinfectors for automatic laboratory glassware preparation are available in various sizes an performance classes. Te prouct range extens from compact macines of 60 to 90 cm wit up to powerful, large capacity macines.

199 08 TECHNICAL INFORMATION PRODUCT SECTION Before purcasing a waser-isinfector, you must first be clear wic laboratory glassware, an ow muc of it, requires reprocessing on a ay-to-ay basis witin te laboratory. Once te macine size is specifie, te appropriate accessories can be iniviually selecte. Te accessories inclue trolleys an inserts for secure support of te laboratory glassware. Inserts are primarily for oling wie-necke laboratory glassware. Special injector trolleys are offere to torougly clean laboratory glassware wit a narrow internal iameter. Tese couple irectly to te water supply of te macine an tus ensure tat even internal cleaning of te laboratory glassware is correctly carrie out. Tis system ensures tat even ifficult-to-access points are cleane, wic woul be very ifficult, or even impossible, to clean manually. Pases of macine-base reprocessing Macine-base reprocessing comprises cleaning, rinsing, isinfection (if necessary) an rying of te laboratory apparatus. Te following figure sows a typical programme cycle for laboratory glassware reprocessing. ( C) Pre-was Alkaline cleaning Aciic neutralisation Intermeiate rinse Intermeiate rinse Final rinse Drying (min.) Programme Universal Cleaning Cleaning removes irt from te surfaces. At tis stage, process cemicals (e.g. cleaning agents, surfactants, emulsifiers, neutralizers) are use. Cleaning may comprise several programme blocks, suc as pre-rinse, cleaning, neutralisation. Example Pre-rinse: col water witout process cemicals Cleaning: col or ot water wit alkaline cleaning agent Neutralisation: col or ot water wit aciic neutralisation Rinsing During rinsing te issolve irt an te process cemicals use are rinse off. Rinsing can comprise a number of iniviual programme blocks. Te coice of water quality (e.g. tap water, eionise water, ultrapure water) epens on te application (e.g. organic/inorganic analysis, microbiology). Example Rinse I: col water Rinse II: eionise or ultrapure water Flusing: eionise or ultrapure water at 75 C Disinfection During isinfection, infectious contamination is kille/inactivate to suc a egree tat te laboratory glassware no longer represents an infection risk. On te one an, isinfection serves to protect personnel witin laboratories wo work wit infectious contamination. On te oter an isinfection prevents transfer of germs from samples an preparations in meical laboratories, ygiene institutes, parmaceutical laboratories an te foo an cosmetic inustries. Tus ygienic, problem-free working is guarantee. Drying Te waser-isinfectors ave, epenent on moel an construction, an active otair ryer wic permits not only rying of te external surfaces, but also rying of narrow iameter laboratory glassware. Also laboratory glassware of complex sape is reliably rie using ot-air rying. To effectively protect te laboratory glassware against ust particles an microorganisms, te rying air is passe troug a HEPA filter. 199

201 2 08 TECHNICAL INFORMATION PRODUCT SECTION Economy Nowaays, laboratory glassware preparation must constantly meet ever iger requirements in respect of performance an economy. Macine-base reprocessing is by comparison wit manual cleaning, muc more efficient: for example, te economy arises from lower time / personnel expenses, sorter process cycles as well as lower power an water consumption. In particular, te sort process cycles mean te laboratory glassware is quickly reay for its next use. Minimal anling of contaminate laboratory glassware simultaneously reuces te potential risk to personnel (injury, cemical burns an risk of infection). Value retention troug gentle preparation Automatic laboratory glassware preparation is gentler tan manual cleaning. Te glass surfaces only comes into contact wit te alkalinity of te etergent for a sort, efine time interval, so tat glass corrosion is minimize. Te accessories inclue special olers an locks so tat te laboratory glassware is securely fastene an protecte against breakage. DWK Life Sciences recommens Miele To guarantee toroug, gentle an safe laboratory glassware preparation, DWK Life Sciences recommens Miele waser isinfectors.

202 08 TECHNICAL INFORMATION PRODUCT SECTION STERILISATION Wen preparing laboratory glass for sterile applications or as part of te cleaning process, sterilisation is a well-establise process. DURAN laboratory glassware is suitable bot for autoclaving as well as for ot air an plasma sterilisation (H 2 O 2 ). Laboratory apparatus tat as come into contact wit infectious substances or microorganisms must be cleane in accorance wit te appropriate guielines for anling tese materials. As te case may be, tis may inclue sterilisation. Wen carrying out sterilisation, especially of laboratory glassware, te following instructions soul be observe: To avoi overpressure, all vessels soul always be kept open. Wen sterilising meia, te use of a membrane cap is recommene. Suc a cap permits pressure equalisation troug a PTFE membrane an ence te cap can be tigtly close. Consequently, te risk of contamination is greatly reuce. Alongsie te stanarise proceures escribe above, iniviually moifie metos are also applicable to all DURAN proucts, for example using iger temperatures. However, you must ensure, especially wit bottles (ue to te screw caps) tat te permissible igest temperatures for te plastic use in te accessories is not exceee. WORKING UNDER PRESSURE Only proucts wose esign inclues te appropriate geometry an wall tickness, an wic are explicitly esignate as suc, are suitable for working uner pressure an / or vacuum (e.g. filtering flasks, esiccators or flat flange vessels). Wen use uner positive or negative pressure, an especially wen also working wit ifferential temperatures, aitional care measures must be taken. Glass apparatus tat is uner pressure or vacuum soul only be subject to furter stress (e.g. significant temperature cange) wit extreme caution, as te iniviual resulting strains are aitive an coul reaily result in failure. To guarantee optimum user safety, te following points soul be borne in min: To avoi stresses in te glass, evacuate vessels or vessels uner pressure soul not be eate on one sie or eate wit an open flame. Wen working uner pressure te maximum figures inicate in te catalogue soul not be exceee. Before using glass equipment uner vacuum or pressure it must always be visually inspecte to ceck tat it is in perfect conition (no serious scratces, micro-cracks, abrasions, etc.). Damage glassware soul not be use for work uner pressure or vacuum for safety reasons. Never subject glassware to suen pressure canges, e.g. always re-pressurise evacuate glass apparatus slowly. Laboratory glassware wit a flat bottom (e.g. Erlenmeyer an flat bottom flasks) soul not be use uner pressure or vacuum. Te plastic coating of laboratory bottles (DURAN protect) as no influence on pressure resistance. Tese proucts are not esigne for use uner pressure. For pressure applications using laboratory bottles, te DURAN pressure plus bottle soul be use. Te DURAN pressure plus bottle is pressure resistant from 1 to bar ue to a moifie geometry an increase wall tickness. 202

203 08 TECHNICAL INFORMATION PRODUCT SECTION SAFETY INSTRUCTIONS Wen use accoring to our specifications, DURAN glassware is very safe to use. Te appropriate guielines applicable for te use of special glass in laboratories in te country in question soul always be complie wit. Te following points soul, owever, be observe in every case: For safety reasons, before DURAN laboratory glassware is use it soul be cecke to ensure tat it is suitable for te intene purpose an tat it can be use witout problem. Defective laboratory glassware represents a risk (e. g. risk of cuts, burns, infection) tat soul not be unerestimate. If appropriate repairs to any item cannot be carrie out or cannot be justifie for economic reasons, it must be ispose of in te proper manner. Only subject DURAN glassware to suen temperature canges witin te recommene limit for termal sock resistance (ΔT = 100 K). Tis means tat ot laboratory glassware soul not be taken out of a rying cabinet an place on a col or even wet laboratory benc. Tis applies in particular to tick-walle glassware suc as filtration flasks an esiccators. Wen assembling apparatus make sure tat it stans firmly an is not subjecte to stress by using appropriate stans. DISPOSAL DURAN laboratory glass soul uner no circumstances be ispose of in te omestic glass recycling stream (e. g bottle banks), since its ig melting point an ifferent cemistry make it incompatible wit oter glass cullet (soa-lime glass) for recycling. Te correct way to ispose of it is, in principle, to inclue it wit general ouseol waste (resiual waste) in accorance wit te relevant guielines, provie tat te glass is quite free of any armful contamination (Waste coe no: ). DURAN LABORATORY GLASS IS ECO-FRIENDLY DURAN laboratory glass is mae from natural, mineral raw materials. Unlike oter materials, laboratory glass, wen use properly, will give years of service an tis means tat it is vastly superior to oter materials from an ecological viewpoint too. Depening on its use, DURAN can be ispose of as ouseol waste an oes not nee to be ealt wit as special waste wic may be environmentally armful. Toxic substances cannot leac out because of te raw materials use. Prouction processes in our factories ave been consistently optimize over recent years to ensure tat tey are environmentally frienly uring te actual manufacturing stage troug te minimum usage of valuable resources. Electrical eating an avance tecnology in our melting units ensure tat no pollutants are release uring manufacture in our ultramoern factories wic coul arm our workers or people living nearby. In aition energy eman is kept as low as possible. Te latest waste gas purification equipment is use to avoi emissions wic coul pollute te environment. A significant investment as been mae in an enclose cooling water recirculation system to cut te amount of fres water require to a minimum tus elping to conserve vital water resources. We use packaging mae from environmentally armless, recycle paper wic can be returne after use to te resource cycle. 203

In tis respect, te following table lists etails of six porosity ranges wit inications of teir main areas of application. A point to be borne in min is tat te filtration equipment soul ieally be selecte to ensure tat te nominal size of te largest pore is somewat smaller tan te smallest particles to be filtere out. Tis will prevent infiltration of particles into of te pores. For quantitative analysis applications, porosity 3 or porosity 4 glass filtration apparatus is use almost exclusively. Different working metos often contain ifferent porosity inications ere for te same materials. Tis is because ifferent processes use in te prouction of precipitations for gravimetric analysis often result in ifferent grain sizes.
