Replacement tips for 2116 style buret

These are replacement Polytetrafluorethylene (PTFE) locking stopcocks for the PYREX® 25 mL and 50 mL Economy Grade Burets (Nos. 2116-25 and 2116-50).

This is a replaceable glass tip for the Polytetrafluorethylene (PTFE) non-locking stopcock assembly No. 2145-SO.

These 10 mL PYREX® burets are suitable for use in school and institutional laboratories not requiring the accuracy of our Class A models. Supplied with a Product Standard Polytetrafluorethylene (PTFE) stopcock plug to reduce freezing and eliminate lubricant contamination. The microfinish of the barrel provides a precision fit. The tips are carefully drawn for accuracy to insure proper drainage rate. Each buret is supplied with…

These burets are designed for precise analytical methods in microchemistry. Precision bore tubing throughout the body assures accuracy between any two points. Funnel top facilitates addition of reagents by pouring, or by suction from below, through a rubber-stoppered tube. Tips are tapered to assure smooth flow. Stopcocks turn freely, yet give positive control and are of 2 mm bore. The capacity tolerance on these burets is est…
