Separatory funnel Separatory funnel A separatory funnel, also known as separation funnel, separating funnel, or colloquially Sami Funnel sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate ("partition") the components of a mixture into two immiscible solvent phases of different densities. Typically, one of the phases will be aqueous, and the other a lipophilic organic solvent such as ether, MTBE, dichloromethane, chloroform, or ethyl acetate. All of these solvents form a clear delineation between the two liquids. The more dense liquid, typically the aqueous phase unless the organic phase is halogenated, sinks and can be drained out
