PYREX 250mL Colored Scale Dispensing Buret with PTFE Stopcock

The PYREX 2094-250 250mL Colored Scale Dispensing Buret is a large-volume laboratory buret designed for rapid and controlled dispensing of liquids. It is particularly suited to school institutional research and general laboratories where reliable volume dispensing is required but Class A accuracy is not necessary. The buret is manufactured from close-tolerance accurate-bore tubing with uniform walls and incorporates a permanently colored scale for easier volume readings. The carefully drawn and ground tip helps provide controlled drainage while reducing susceptibility to chipping. Its straight-bore PTFE stopcock plug is designed to reduce freezing and eliminate the lubricant contamination associated with lubricated glass stopcocks. Corning specifies a smooth micro-finished stopcock barrel for precision fit and leak-resistant performance.
