The PYREX^® Class B Straight Bore Buret with PTFE Resin Stopcock has a colored scale. This combined with a carefully drawn tip ensures a proper drainage rate. This buret features a 2mm bore. Less accurate than the PYREX® class A buret, this buret is recommended for school laboratories.

The PTFE resin creates a non-stick surface. This feature also reduces freezing and eliminates lubricant contamination.

Precision bore tubing ensures accuracy between any two points. Capacity tolerance is established by ASTM E-287. They are calibrated in accordance with ASTM E542.
