Pear-shaped, Glass Separatory Funnels for Liquid-Liquid Extractions
Separatory Funnels with lower stems have an I.D. large enough that a column of liquid will “break” with the stopcock closed, giving more complete separation and eliminating the need to empty the funnel. Stems are 60mm long. Separatory Funnels are supplied with a ground glass stopper and PTFE stopcock.
