Pyrex Class A Volumetric Flasks with Taper Glass Stopper

These PYREX® Class A Volumetric Flasks with Standard Taper Glass Stopper provide improved lab convenience, broad selection and precise volume measurement. The strength of these flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-tubing necks tooled for Standard Taper glass stoppers; see size in table below. The graduation line is sharp and permanent and large white block letters make the inscription easy to read. These Class A volumetric flasks have been manufactured to Class A tolerances as established by ASTM E- 694 for volumetric ware, ASTM E-542 for calibration of volumetric ware and ASTM E-288 for volumetric flasks.

Serilized/Certified models are tested and calibrated in an ISO/IEC 17025 certified laboratory, individually serialized, and supplied with a Certificate of Identification and Capacity, traceable to NIST Standards.
