PYREX 50mL Serialized Certified Class A Precision Bore Buret with Glass Stopcock

The PYREX 2135-50 50mL Serialized Certified Class A Precision Bore Buret is high-accuracy volumetric laboratory glassware designed for precise titration and quantitative analytical work where measurement traceability is required. Precision-bore tubing helps maintain accuracy between different points on the buret. The 50mL buret has 0.1mL graduations with a 0.05mL Class A tolerance and uses a carefully ground straight-bore glass Standard Taper stopcock for controlled liquid delivery. Each buret is individually serialized and has access to a Certificate of Identification and Capacity traceable to NIST standards. Corning states that the product is tested and calibrated in an ISO/IEC 17025 certified laboratory.
