PYREX 25mL Serialized Certified Class A Precision Bore Buret with Glass Stopcock

The PYREX 2135-25 25mL Serialized Certified Class A Precision Bore Buret is precision volumetric glassware designed for accurate titration and quantitative laboratory analysis where measurement traceability and documented accuracy are required. The buret combines precision-bore tubing with Class A volumetric accuracy and a carefully ground straight-bore glass Standard Taper stopcock for controlled dispensing. Each buret is individually serialized and certified, providing greater traceability for quality-control, analytical and regulated laboratory environments. Corning states that the serialized/certified 2135 series is tested and calibrated in an ISO/IEC 17025 certified laboratory, with certification traceable to NIST standards.
