The FEP separatory funnel is mainly used in solid-liquid or liquid to liquid reaction experiments to control the amount of liquid added, the size of the reaction rate, and the separation and purification of substances. It separates the two immiscible liquids formed after extraction. FEP separatory funnel has the characteristics of high and low temperature resistance, strong acid and alkali corrosion resistance, and non polluting experimental samples, so it is widely used in industries such as isotope, heavy metal detection, and biopharmaceuticals. The usage method of FEP separating funnel is as follows: 1. Control liquid flow rate: The piston in the separating funnel can control the flow rate of the liquid. By adjusting the opening and closing degree of the piston, the droplet acceleration of the liquid can be precisely controlled. 2. Stop reaction: When it is necessary to stop the reaction, the piston can be tightly closed to immediately stop the dripping of liquid. 3. Liquid separation operation: According to the principle of "downward flow and upward flow", open the piston to allow all the lower liquid to flow out, then close the piston and pour out the upper liquid from the top. 4. Cleaning and maintenance: After use, it is necessary to wash thoroughly. If the separating funnel is not used for a long time, the plug should be wiped clean and a rubber band should be used to cover the piston to prevent adhesion at the frosted area.
