Heavy, heat resistant Borosilicate (Pyrex type) glass Separatory Funnel. Used for separating liquids of different densities, the "Sep Funnel" allows you to drain off the heavier, denser liquid from the bottom. Precision fitting Teflon valve ensures silky smooth operation that will not seize up like cut-rate glassware frequently does. Use a 3-Finger clamp and Support Ring to hold/support Sep Funnels.
