Permanent Magnetic Agitator

A permanent magnet stirrer utilizes the magnetic field generated by permanent magnets to drive the rotation of a magnetic stir bar inside a container, achieving liquid mixing. It transmits power through a non-contact method, avoiding sealing issues, and is suitable for scenarios such as small-batch sample stirring in laboratories and mixing chemical reactions.
Selection
When selecting a permanent magnet stirrer, consider the compatibility of the container material and shape with magnetic field penetration. The size of the magnetic stir bar should match the container capacity and viscosity. The speed range should cover operational needs, and heating functionality should be chosen based on temperature control requirements. Additionally, pay attention to the stability and wear resistance of the magnetic coupling.
