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

The KIMAX® Squibb pear-shaped separatory funnel is supplied with a ground glass stopcock and stopper. 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. Replacement Stopper: 41900R.
