Several problems that should be paid attention to during the use of magnetic stirrer

At present, there are mainly two types of stirrers used in laboratory reactors: electric stirrers and magnetic stirrers. Among them, the magnetic stirrer is suitable for mixing and stirring thinner liquids. Here, briefly introduce a few issues that should be noted during the use of the magnetic stirrer:

First, when using for the first time, first check whether the accessories provided with the instrument are complete according to the instrument manual, such as the stirring bar, power cord, etc .;

Second, the speed should be gradually adjusted from low speed to high speed, it is best not to start directly at high speed, so as not to cause the mixer to be out of synchronization and cause jump
Third, it cannot be heated without stirring, and the power supply should be cut off when not working;

Fourth, the instrument should be kept clean and dry, especially do not let the solution enter the machine;

Fifth, if you find that the stirring bar is jumping or not stirring, please check whether the beaker is stable and the position is correct;

Sixth, medium-speed operation can extend the life of the mixer;

Seventh, it is best to be able to connect to the ground when using
