PYREX® Mixing Bulb Volumetric Flasks, Class A, Corning 5820

These PYREX® Class A mixing bulb volumetric flasks have an upper bulb, located between the standard taper stopper and the capacity graduation, to assist in the mixing of liquids or powders when shaken. This bulb is approximately one-tenth the flask rated capacity of the flask. The strength of this flask results from the use of a machine blown body which is sealed to a heavy-tubing neck tooled for a No. 13 standard taper glass stopper. The Class A mixing volumetric flask has 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
