PYREX 25mL Class A Precision Bore Buret with Glass Stopcock

The PYREX 2130-25 25mL Class A Precision Bore Buret is precision volumetric laboratory glassware designed for accurate titration and quantitative analytical procedures. Corning uses precision-bore tubing to maintain accuracy between points along the buret. The durable colored graduations are sharply defined for easy reading, while the carefully ground straight-bore glass Standard Taper stopcock provides precise control of liquid delivery. Each buret is also supplied with a dust cover. The 25mL version provides 0.1mL graduations with a 0.03mL tolerance. Corning states that capacity tolerance is established according to ASTM E-287 and calibration is performed according to ASTM E542.
