Magnetic agitator is a laboratory instrument for liquid mixing. It is mainly used for stirring or heating at the same time to stir liquid or solid-liquid mixtures with low viscosity. Its basic principle is to use the magnetic field of the same repel, opposites attract principle, using magnetic field to push the magnetic agitator placed in the container for circular movement, so as to achieve the purpose of stirring liquid. With the heating temperature control system, it can heat and control the sample temperature according to the specific experimental requirements, maintain the temperature conditions required by the experimental conditions, and ensure that the liquid mixture meets the experimental requirements.

Working principle of magnetic agitator

The magnetic agitator is driven to rotate by constantly changing the polarity at both ends of the base, and the magnetic agitator drives the sample to rotate, so that the sample is evenly mixed.

The sample is heated by the bottom temperature control plate, and the sample is heated evenly with the rotation of the magnetic agitator to reach the specified temperature.

Through the regulation of heating power, the heating rate can be controlled so as to apply to a wider range of sample processing.

General magnetic agitator has two functions: stirring and heating.

Specific as follows:

* action, so that the reactants mixed evenly, so that the temperature is uniform;

The second effect is to speed up the reaction, or the rate of evaporation, and shorten the time.

Notes for magnetic agitator

1. If the agitator beats or does not stir, please cut off the power to check whether the bottom of the beaker is flat and the position is correct. Meanwhile, please measure it.

2, heating time is generally not too long, intermittent use to extend life, do not heat when stirring.

3, work to prevent violent vibration.

4. Power consumption: the power socket shall be three-hole safety socket, which must be properly grounded.

5. The instrument should be kept clean and dry. Solution should not be allowed to flow into the machine to avoid damage.
