PYREX 500mL Colored Scale Dispensing Buret with PTFE Stopcock

The PYREX 2094-500 500mL Colored Scale Dispensing Buret is designed for rapid and controlled dispensing of relatively large volumes of laboratory liquids. It is particularly suited to school and institutional laboratories and other applications that do not require Class A buret accuracy. The buret is manufactured from close-tolerance accurate-bore tubing with uniform walls and incorporates a permanently colored scale for clear volume readings. Its carefully drawn and ground dispensing tip helps maintain appropriate drainage while reducing susceptibility to chipping. A straight-bore PTFE stopcock plug provides controlled liquid flow while helping reduce stopcock freezing and avoiding lubricant contamination. Corning uses a micro-finished stopcock barrel to provide a precise fit and leak-resistant performance.
