PYREX 10mL Class A Precision Bore Micro Buret with Glass Stopcock

The PYREX 2128-10 10mL Class A Precision Bore Micro Buret is designed for high-precision analytical procedures in microchemistry. Precision-bore tubing throughout the body is intended to maintain accuracy between different points on the buret scale. Its funnel top facilitates reagent addition either by direct pouring or by suction from below through suitable tubing. The tapered dispensing tip promotes smooth flow while the 2mm straight-bore glass stopcock provides positive control of liquid delivery. The 10mL model has very fine 0.02mL graduations and a ±0.02mL tolerance. Corning states that the capacity tolerance is established according to ASTM E-1189, with calibration in accordance with ASTM E-542.
