PYREX 100mL Serialized Certified Class A Buret with PTFE Stopcock

The PYREX 2105-100 100mL Serialized Certified Class A Buret is precision volumetric laboratory glassware intended for highly accurate titration and quantitative liquid measurement where documented calibration and traceability are important. Each buret is individually serialized and comes with access to a Certificate of Identification and Capacity traceable to NIST standards. Corning states that the 2105 series is tested and calibrated in an ISO/IEC 17025 certified laboratory and calibrated to Class A tolerances in accordance with ASTM D-511 ASTM E-542 and ASTM E-287. The 100mL model provides 0.2mL graduations with ±0.10mL tolerance. Its colored scale features fine graduation lines and large numbers for easier readings. The 2mm-bore PTFE stopcock provides controlled dispensing and eliminates the need for a conventional lubricated glass stopcock.
