PYREX 25mL Serialized Certified Class A Buret with PTFE Stopcock

The PYREX 2105-25 25mL Serialized Certified Class A Buret is precision volumetric laboratory glassware designed for highly accurate titration liquid measurement and quantitative analysis where documented calibration and traceability are required. Unlike a standard Class A buret, each buret in this PYREX series is individually serialized and provided with access to a Certificate of Identification and Capacity. Corning specifies that the certification is traceable to NIST standards and that the burets are tested and calibrated in an ISO/IEC 17025 certified laboratory. With a 25mL capacity 0.1mL graduation interval and ±0.03mL tolerance, the buret is suited to analytical procedures requiring precise controlled liquid delivery. The colored scale provides clear visibility of graduation lines while the 2mm straight-bore PTFE stopcock plug allows smooth controlled dispensing without the conventional greasing associated with glass stopcocks.
