Magnetic agitator is suitable for stirring or heating at the same time, suitable for the viscosity is not very big liquid or solid liquid mixture. Using the principle of magnetic field and whirlpool, the liquid is put into the container, and the agitator is put into the liquid at the same time. When the magnetic field is generated in the base, the agitator is driven to move in a circular circle, so as to achieve the purpose of stirring the liquid. With the temperature control device, the sample temperature can be controlled and maintained according to specific experimental requirements, helping the experimenter set experimental conditions, which greatly improves the possibility of experimental repeatability. Magnetic agitators are usually suitable for food, biopharmaceutical and other fields. With the higher requirements of biopharmaceutical on the sterility and risk control of agitator shaft seals, industrial magnetic agitators emerged in Sweden in the 1980s. Magnetic agitators become the mainstream of the market, and continue to develop towards the direction of simplicity, high torque, large shear force or very low shear force, safe bearing material, easy online cleaning and online sterilization.

If the magnetic agitator fails in use, users can refer to the following methods:

1. Rotor cleaning: when the magnetic stirrer stirs the solution, the rotor is easy to get dirty. First, neutralize the solution and then rinse with water. If the cleaning is not clean, check whether the outer white plastic envelope of the rotor is damaged. If it is damaged, it is recommended to replace it.

2. How to choose the rotor of magnetic agitator: the size of the rotor should ensure good mixing effect and match the size of your beaker.

3. The rotor of magnetic agitator does not move: check whether the stirring viscosity is too high and the magnetic force is not enough; Whether need to change a high power magnetic agitator or mechanical, electric agitator. If it is not the reason for stirring the sample, please check whether it is the problem of the accessories of the magnetic stirrer and contact the after-sales service.

4. How to effectively extend the service life of magnetic agitator: it is recommended to choose medium speed speed regulation when stirring. When using, the power supply should be adjusted from low speed to high speed after starting, so as to prevent direct adjustment to high speed from causing stirring skip, affecting the normal start and reducing the service life of magnetic agitator.
