Simple illustration of a separatory funnel

Separation funnel is a glass experimental instrument mainly used to extract liquid and control the reaction rate. Divided into ball, pear and barrel and other styles.

Including the bucket body, the bucket cover covering the upper mouth of the bucket body. A piston with a three-way structure is installed at the lower opening of the bucket body, and the two-way connections of the piston are respectively connected with the two lower pipes. It is practical to use, which can facilitate the control of the experimental operation process and reduce the labor intensity. When the amount of liquid to be separated is large, the two liquids in the bucket can flow to the lower pipe at the same time by moving the three-way of the piston, without changing the container. Can be done in one go. The main function of the separatory funnel in the junior high school stage is to control the rate of chemical reactions.
