These Kimble 29048 KIMAX Squibb Pear-Shaped Separatory Funnels are 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, Type 4 requirements. Replacement stopper is 850100.
