Corning Pyrexplus 65640-200 200ml Coated Class A Flat Bottom Volumetric Flask with Glass Standard Taper Stopper (Case of 12)

These 200mL Class A Pyrexplus-coated volumetric flasks feature a protective PVC coating for longer product life and safety. Protective coating helps prevent glass from shattering and reduces spills. Flasks are autoclavable (121 degree Celsius) and resistant to thermal shock. The strength of these flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-tubing necks tooled for No. 13 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.
