Magnetic stirrer is used for stirring or heating and stirring at the same time, and suitable for liquid or solid-liquid mixture whose consistency is not particularly high. Now it has been widely applied in laboratories of colleges and universities, environmental protection, scientific health, epidemic prevention, petroleum, metallurgy, chemical, medical industries.

When purchasing laboratory magnetic stirrer, the following aspects should be considered:

1. For stirring at room temperature, choose a simple magnetic stirrer only with stirring function;

2. For stirring and heating at the same, but without strict temperature requirements, a standard hotplate magnetic stirrer should be selected;

3. If it requires to display the temperature in real time during work, a digital temperature heating magnetic stirrer is better choice;

4. If it requires to set working time and automatically stop after the time is up, you can choose a magnetic stirrer with timing function;

5. If the heating temperature control is strictly required, a water bath collector magnetic stirrer or a submerged magnetic stirrer should be selected.

6. If it requires to accurately display the real-time speed during work, do choose a digital display speed heating magnetic stirrer, which is usually more expensive, so it is recommended for demanding research occasions;

7. If the amount of liquid to be stirred is large, a large-capacity magnetic stirrer should be selected. The stirring capacity of conventional magnetic stirrers is usually less than 2000ml.
