Magnetic stirrer is a laboratory instrument used for liquid mixing, mainly used for stirring or simultaneously heating and stirring low-viscosity liquid or solid-liquid mixture. The basic principle is to use the principle of repulsion of the same sex and attraction of the opposite sex of the magnetic field, and use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, so as to achieve the purpose of stirring the liquid. With the heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements, and the temperature conditions required by the experimental conditions can be maintained to ensure that the liquid mixing meets the experimental requirements.
