Separating funnel or a funnel separation is laboratory equipment used in liquid-liquid extraction to separate the components of a mixture between the two solvent phases with different densities that do not interfere.

Typically, one phase will be aqueous and the other a lipophilic organic solvent such as ether, MTBE, dichloromethane, chloroform, or ethyl acetate. Most organic solvents are in the water phase, except that the solvent halogenated.

Separating funnel-shaped cone surmounted by a hemisphere He has a stopper on top and underneath the faucet Separating funnel used in the laboratory are made of borosilicate glass and the faucets are made of glass or Teflon. Typical sizes are between 50 mL and 3 L. In industrial chemistry can be sized and installed centrifuges

To use this funnel, and two-phase mixture of solvent incorporated into the funnel from the top with the tap closed funnel. The funnel is then closed and shaken vigorously to make the two phases into. The funnel is then inverted and the tap opened to release excess vapor pressure. The funnel is set aside to allow the separation between the phases. The top and then opened the tap funnel and two phases separated by controlling the tap funnel
