PYREX 10mL Serialized Certified Class A Buret with PTFE Stopcock

The PYREX 2105-10 10mL Serialized Certified Class A Buret is precision volumetric laboratory glassware designed for high-accuracy titration and quantitative liquid measurement where documented calibration and traceability are required. Each buret is individually serialized and has an accessible Certificate of Identification and Capacity traceable to NIST standards. Corning specifies calibration to Class A tolerances in accordance with ASTM D-511 ASTM E-542 and ASTM E-287. The 10mL buret provides fine 0.05mL graduation intervals with a tolerance of ±0.02mL. Colored markings with fine graduation lines and large numbers improve readability during precise titration work. A 2mm straight-bore PTFE stopcock plug provides controlled liquid dispensing. Corning also supplies the buret with a dust cover and identifies 7681-2 as the replacement PTFE stopcock plug.
