Use a Separatory Funnel to
Separate Immiscible Liquids
1. Use a separatory funnel that will hold at least twice the total volume of solution to be
extracted and the extraction solvent.
2. Support the funnel in a ring stand and pour the solution to be extracted into the funnel.
3. Next, pour the extraction solvent into the funnel.
4. Stopper the funnel and hold the stopper in place.
5. Invert and gently swirl the funnel. Do not shake the funnel or an undesirable emulsion may form.
6. While the funnel is inverted, open the stopcock to release the built-up pressure.
7. Close the stopcock and repeat steps 5 and 6 several times.
8. Place the funnel back in the ring support and allow the two layers to separate.
9. Remove the stopper and open the stopcock to drain off the bottom layer.
