The magnetic stirrer is a laboratory instrument for liquid mixing, is mainly used for stirring or simultaneously heating and stirring liquid or solid-liquid mixture with low viscosity, and has the basic principle that the magnetic stirrer placed in a container is pushed by a magnetic field to perform circumferential operation by utilizing the principle that like poles repel and opposite poles attract of the magnetic field, so that the aim of stirring the liquid is fulfilled.

The magnetic stirrer changes the dynamic sealing structure which can pass through a shaft sleeve or a packing seal stirring shaft and is a static sealing structure of the traditional mechanical seal and packing seal, adopts the static sealing structure, adopts the magnetic coupler for connection between the stirrer and the motor transmission, and replaces the dynamic seal with the static seal due to the non-contact transmission torque, so that the leakage problem which cannot be solved by the traditional mechanical seal and packing seal can be thoroughly solved, and all stirring parts of the whole medium are completely in a sealed state to work.

The magnetic stirrer is adopted to ensure that the medium in the reaction kettle is completely positioned in the sealing cavity formed by the kettle body and the kettle cover, the problem of the leakage which cannot be overcome due to the dynamic sealing of the packing seal and the mechanical seal is thoroughly solved, the reaction medium has no leakage or pollution at all, the device is the most ideal device for carrying out chemical reaction under high temperature and high pressure, and particularly, the device shows the superiority when carrying out the chemical reaction of inflammable, explosive and toxic media.
