Magnetic stirrer use steps and precautions in the laboratory

The magnetic stirrer in the laboratory is suitable for liquids with a small viscosity, solid-liquid mixture, using the principle of magnetic field and eddy, and has the characteristics of low working voltage, high power, low noise, stable operation, safety and reliability.

When using an electronic magnetic stirrer, first check that the random accessories are complete, then install the clamps in sequence, add the desired stirred solution to the container, add a stirrer, and place the container on the stirring heating work plate. Connect the two signal wires on the self-contained electrical contact thermometer to the terminal on the back of the unit, and insert the thermometer into the solution and fix it on the fixture.

Note for magnetic stirrer:

The first speed regulation should be gradually adjusted to high speed from low speed. It is best not to start directly at high speed to avoid the stirrers being out of sync and causing jumping;

In the third use, it is better to connect the ground wire.

The fourth can not be heated without stirring, and should be cut off when not working;
