PYREX® 10mL Class A Buret with Product Standard PTFE Stopcock Plug

The PYREX 2103-10 10mL Class A Buret is a precision volumetric instrument designed for accurate measurement and controlled dispensing of small liquid volumes in analytical laboratory procedures. It features fine permanently colored graduations with large easy-to-read numbers. Its capacity tolerance is established according to ASTM E-287, while calibration is performed in accordance with ASTM E-542. The carefully formed tip is made from accurate-bore tubing to provide appropriate drainage characteristics. The buret incorporates a 2mm straight-bore PTFE stopcock plug. The micro-finished stopcock barrel provides a precision fit for leak-resistant operation, while the PTFE plug avoids the need for conventional stopcock lubricant. A dust cover is supplied with the buret.
