Two immiscible liquids having different densities such as water and oil, or water and glycerine can be separated using a separating funnel

The mixture of liquids is first taken in the separating funnel and are left for some time undisturbed. they form two separate layers with the liquid having lower density on top of the liquid having higher density.

the stopcock is opened so that the higher density liquid comes out and the stopcock is closed just as the lower density liquid reaches the stopcock.
