Magnetic stirrers are laboratory instruments used for mixing liquids or solid-liquid mixtures, stirring or simultaneously heating and stirring low viscosity liquids or solid-liquid mixtures. The principle of using a magnetic field to test the vortex generated by the stirrer rotating in isolation is to use a magnetic field to push the stirrer placed in the container for circular operation. When a certain speed is reached, the vortex is generated to stir the liquid. Combined with a constant temperature heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements, maintaining the temperature conditions required for experimental conditions, and ensuring that the liquid mixture meets the experimental requirements.
