Kimble® KIMAX® Pear Shaped Squibb Separatory Funnels with Standard Taper Stopper and PTFE Stopcock Plug

These KIMAX® separatory funnels are supplied with a standard taper ground glass stopper and a totally autoclavable polytetrafluoroethylene (PTFE) stopcock plug. Lower stems have an I.D. large enough so 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 41900R.
