2 2 BURETS Serialized Class A / Class B Funnel Fill Buret Buret Types Reservoir Fill Buret 462F Kimble offers unmatched quality in materials and craftsmanship. Our selection of burets reflects many notable innovations. All have a high resistance to both chemical attack and mechanical shock. Only the finest accurate-gauge or precision-bore heavy-walled tubing is used to insure precise calibration and long service. Colored markings, large numerals and sharp, fine-line divisions make these burets easy to read; markings on scales are permanently fused. Most burets are supplied with KIM-KAP dust caps. Careful study of the complete line will enable you to realize full economy. For example, you may buy general purpose burets without polytetrafluoroethylene (PTFE) stopcock plugs thus permitting a savings. s accepting glass plugs have a :0 standard taper and satin finished surfaces (ASTM E675). PTFE plugs have a :5 taper and are engineered with a mirror finish barrel to assure leakproof seating, smooth turning, and correct alignment (ASTM E9). PTFE plugs are self lubricating, non-contaminating and will not freeze in the stopcock barrel, even after repeated use with strong alkali solutions. When not in use or for prolonged storage, loosen plug to prevent cold flow distortion into the glass barrel. Burets with side filling tubes use /4 inch I.D. flexible tubing. Delivery end of pinch clamp style burets accept 5/6 inch I.D. tubing except for 708 dispensing burets which utilize 3/8 inch I.D. tubing. When you need a buret, Kimble has exactly what you need. s with polytetrafluoroethylene (PTFE) plugs Serialized and Certified Class A Burets with Straight Bore PTFE Used for general purpose titrations requiring Precision bore buret is permanently marked with an individual serial number and is traceable to NIST standards Delivery stem of the 0 ml size is 5 mm long to meet of potentiometric titration burets (ASTM D664) and a KIM-KAP dust cap Replacement 2 mm straight bore stopcock plug is Designed from ASTM Specification E287, Class A Manufactured from 33 expansion, expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A 7054F 7027F-0 0; ± F-25 25; ± F-50 50; ± F-00 00; ± Airtight fit to prevent leakage. :5 taper to prevent binding over a wide temperature range.

4 BURETS Class A / Class B / Automatic Zero Class A Serialized and Certified Automatic Zero Burets with PTFE and Reservoir Bottle KIMAX precision bore automatic burets are used in applications

4 4 BURETS Class A / Class B / Automatic Zero Class A Serialized and Certified Automatic Zero Burets with PTFE and Reservoir Bottle KIMAX precision bore automatic burets are used in applications requiring the highest degree of precision and accuracy for volumetric analysis. These are ideal for repeat titrations requiring traceable volumetric accuracy or when the titrant should not be handled. Packed complete with a reservoir bottle, U-shaped drying tube, vented connecting tube, rubber squeeze bulb, # single-holed rubber stopper, PTFE stopcock plug and /4 inch ID rubber tubing Precision ground tips assure uniform outflow Permanently marked with an individual serial number and traceable to NIST Standards Easy-to-read durable black enamel scale Replacement 2 mm bore size stopcock plug is ASTM Specification E542 borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A Procedure for Using Automatic Buret 724F: Place the one-holed rubber stopper, large end first, on the lower tubulation of the buret. Add the U-shaped drying tube, prefilled with drying medium, over the small end of the stopper. Join the drying tube to the connecting tube and then the rubber squeeze bulb with the rubber tubing. To fill the buret, turn the stopcock to connect, filling tube to the buret. Squeeze the rubber bulb several times while closing the vent hole in the connecting tube with your finger. As liquid rises and overflows from the tip above the buret, turn the stopcock to off and remove your finger from the vent hole of the connecting tube. If air is trapped in the stopcock or tip, discharge the air and repeat the filling operation to automatic zero at overflow tip.
