PYREX® Brand 5580 Class A Volumetric Flasks

Easy and accurate dilutions—sharp line for precise volume

These Class A glass volumetric flasks feature a durable, machine-blown body with a heavy-beaded tubing neck tooled to fit a snap-cap. The graduation line is sharp and permanent large white block letters make the inscription easy to read. The 1-mL and 2-mL sizes are test tube shaped. The 10-mL through 2000-mL sizes are supplied with LDPE snap-caps.
Flasks are 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.
