Kimble® KIMAX® Squibb Separatory Funnels with PTFE Stopcock & [ST] Polyethylene Stopper

KIMAX® Squibb pear-shaped separatory funnel is supplied with a plastic stopper and a PTFE stopcock. Lower stems have an I.D. large enough that a column of liquid will "break" with the stopcock closed, thereby giving a more complete separation and eliminating the necessity of emptying the funnel. Designed from ASTM Specification E1096 and Type 4 requirements.
