PYREX® 4L Class A Volumetric Flasks with PYREX® Glass Standard Taper Stopper

These PYREX® 4L volumetric flasks 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 No. 38 Standard Taper pennyhead glass stoppers. 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.

One or more facilities manufacturing this product is 100% covered by renewable energy through the purchase of unbundled energy attribute certificates (EACs).
