The role of magnetic stirrer

Generally have two functions of stirring, heating

1. Mix the reactants evenly to make the temperature uniform.

2, heating in a closed container, need to prevent bumping, for example, in the distillation process, you can add zeolite, you can also use a magnetic stirrer,

3. Speed ​​up the reaction, or evaporate, and shorten the time.

Principle of magnetic stirrer

The working principle of the magnetic stirrer is that the micro-motor drives the high-temperature resistant magnet to rotate to generate a rotating magnetic field to drive the stirrer in the container to rotate, so as to achieve the purpose of stirring the liquid in the container. At the same time, the solution can be heated simultaneously, so that the solution is sufficiently mixed and reacted at a set temperature.

Magnetic stirrer features

Both the agitation speed and the heating temperature can be continuously adjusted (temperature adjustment step is 1. C), which is widely used for agitation of solvents with different viscosities.

The heating plate is made of aluminum alloy, and the Teflon material is sprayed on the outside to make it have good thermal conductivity and strong resistance to cold and heat.

A double-heating device is used on the bottom of the heating plate to increase efficiency and prevent heat from being conducted to the casing.

The integral design of the casing and the upper part of the casing can effectively prevent the inadvertently spilled solution from flowing into the agitator and damaging the electronic components during the agitation process.

Magnetic stirrers are widely used in biology, medicine, chemistry, and chemical industries.
