Separating Funnel

A separatory funnel, also known as a separation funnel, separating funnel, or colloquially 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.[1] 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.[2] The more dense liquid, typically the aqueous phase unless the organic phase is halogenated, sinks to the bottom of the funnel and can be drained out through a valve away from the less dense liquid, which remains in the separatory funnel

分液漏斗或通俗的sep漏斗，是一種用於液-液萃取的實驗室玻璃器皿，用於將混合物的組分分離（分配）成兩個不同密度的不混溶溶劑相。[1] 通常，其中一相是水相，另一相是親脂性有機溶劑，如乙醚、MTBE、二氯甲烷、氯仿或乙酸乙酯。 所有這些溶劑在兩種液體之間形成清晰的界限。[2] 密度較大的液體（通常為水相，除非有機相被鹵化）沉至漏斗底部，並可透過閥門從保留在分液漏斗中的密度較小的液體中排出。
