PYREX Class A Volumetric Flask with Snap Cap
The strength of these flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-beaded, heavy-tubing necks, tooled for snap cap fit. The graduation line is sharp and permanent. The 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. The 1 and 2mL sizes are test tube shaped. The 10 through 2000mL sizes are supplied with snap caps. Non-sterile.
