Magnetic stirrer is a laboratory instrument used for liquid mixing, mainly for stirring or simultaneously heating and stirring low viscosity liquids or solid-liquid mixtures. Its basic principle is to use the magnetic field to repel and attract the same and opposite materials, and to use the magnetic field to push the magnetic stirrer placed in the container to rotate in a circular motion, thereby achieving the purpose of stirring liquids. Combined with the heating temperature control system, the sample temperature can be heated and controlled according to specific experimental requirements to maintain the temperature conditions required for the experiment and ensure that the liquid mixture meets the experimental requirements.

Precautions for using magnetic stirrer:

1. If you find that the stirrer is jumping or not stirring during mixing, please cut off the power and check if the bottom of the beaker is flat and the position is correct. At the same time, please measure the current voltage.

2. The heating time should generally not be too long, intermittent use can prolong the service life, and heating should not be done when not stirring.

3. Medium speed operation can work continuously for 8 hours, high-speed operation can work continuously for 4 hours, and prevent severe vibration during operation.

4. Electricity: The power socket should use a three hole safety socket and must be properly grounded.

5. The instrument should be kept clean and dry. It is strictly prohibited for the solution to flow into the machine to avoid damaging it. The power should be cut off when it is not working.
