Centrifugal precipitator is a teaching tool used in chemical experiments for rapid separation of liquids and suspended particles. It consists of an electric drive device, a rotating tray, and a centrifuge tube fixing groove. Through centrifugal force, the denser precipitate is quickly gathered at the bottom of the centrifuge tube. In teaching, it is suitable for precipitation separation of small amounts of solutions, using centrifugal force to accelerate precipitation settlement, replacing traditional static precipitation, and saving experimental time. Helping students understand the principle of centrifugal separation, quickly obtaining clear supernatant for subsequent detection, and improving experimental efficiency is a convenient auxiliary tool for chemical separation experiments.
