Rotary Magnetic Stirrer

The rotor magnetic stirrer drives a magnet to rotate via a motor, which synchronously rotates the magnetic rotor inside the container to achieve liquid mixing. It is used in laboratories for dissolving, reacting, or uniformly mixing samples, avoiding direct contact with the samples and facilitating cleaning. It is commonly used for small-scale liquid handling in industries such as chemical and coatings.
