How Do Magnetic Stirrers Work? Stirring Hot Plate Working Principle
Laboratory magnetic stirrer hotplate is often used in chemistry and biology, through place the magnetic bar within the liquid to do stirring action. -
1. Laboratory magnetic stirrer hotplate
is quieter, more efficient, and don’t need moving external parts to assist.2. For chemical reactions, magnetic stir bars could work well in glass vessels,
3. Magnetic stirrer often is small size, so compared with other stirring devices, it’s more easily cleaned & sterilized.
4. Heating function is available for magnetic stirrer hotplate, so you don’t need to find other means to heat the liquid. Make your stirring research very convenient and be efficient.

So magnetic stirrer is suitable for all chemical stirring experiment?
Of course no, in the below situations, you also need to consider other type stirring apparatus:
1. As the magnetic stirrer bar limited size, magnetic stirrer with heating is often used in relatively small experiments, such as 4 liters or less stirring capacity.
2. Magnetic stir bars also have difficulty in dealing with viscous liquids or thick suspensions.
3. So if you want to do larger capacity or more viscous liquids stirring experiment, some sort of mechanical stirring is typically needed.
