Description

Volumetric Flask, 500mL Class A with included Pyrex Stopper # 19. These PYREX volumetric flasks provide improved lab convenience, broad selection and precise volume measurement. The strength of the flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-tubing necks tooled for Standard Taper 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.
