A magnetic stirrer is a laboratory instrument used for liquid mixing. It is mainly used to stir or heat and stir low-viscosity liquids or solid-liquid mixtures at the same time. The basic principle is to use the principle of magnetic field that like charges repel and opposite charges attract, and use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circle, thereby achieving the purpose of stirring the liquid. In conjunction with the heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements, maintaining the temperature conditions required by the experimental conditions, and ensuring that the liquid mixing meets the experimental requirements.
