Analysis of two functions of heating magnetic agitator:

1. Heating function: generally, heating magnetic agitator is equipped with heating device on the chassis. In addition, corresponding devices will be set to monitor the heating.

2. Stirring function: drive the magnetic agitator through the * magnet located under the working disc. * magnet can penetrate the working disc surface, and the magnet is fixed directly on the rotating shaft of the motor. The actual rotating speed of the instrument depends on the actual load and voltage. The fluctuation of the voltage within the permissible range and the change of the viscosity of the treated medium will cause the fluctuation of the rotating speed. The speed of the motor can be adjusted according to the requirements of the experiment.

When heating magnetic agitator, the following matters should be noted:

1. Do not use heated magnetic stirrer for stirring explosive substances in dangerous environment or underwater operation.

2. Only trained personnel should be allowed to use the heated magnetic stirrer.

3. Avoid the instrument power cord from touching the chassis.

4. Wear appropriate protective equipment according to the type of treatment medium.

5. The instrument should not be used to deal with explosive media indoors. The instrument should be placed on a table that is not flammable or fireproof.

6, pay attention to the magnetic field! Consider the influence of magnetic field on the surrounding environment, such as data storage and cardiac pacemaker.

Be careful of the heat! When the instrument is working, the dish surface temperature zui can reach several hundred degrees Celsius. Be careful to burn when touching the shell and dish surface of the instrument, and pay attention to the residual heat when the instrument is turned off.

8. When heated and cooled, a slight sound may be made as a result of the expansion of matter.
