The unique design of the Chem-Drain valve incorporates a Teflon plunger that allows the contents of the flask to drain directly through the bore of the plunger (B). When closed, the tip of the Teflon plug seals into the lower radius of the flask (A) avoiding the dead space normally associated with standard stopcock drains. This feature permits total mixing and drainage of the contents of the flask. The Chem-Drain valve is available in 2 sizes: 6mm and 12mm. This dimension refers to the straight section of the plunger (B). When open, the contents of the flask drain through three openings into the main bore of the plug. Lower portion of the plunger (C)
