Separatory Funnels

Separatory funnels are used in the lab for liquid-liquid extractions, separating a mixture's components into two solvent phases of different densities. The higher density liquid sinks to the bottom and can then be drained from a valve, leaving the less dense liquid in the funnel. Separatory funnels feature a stopcock at the bottom that can be opened or closed to drain liquid, as well as a tap at the top that can be opened to release excess vapor pressure. The funnels are typically constructed from borosilicate glass, which is stronger than regular glass and resistant to thermal shock.
