A magnetic stirrer is a laboratory instrument used for liquid mixing or simultaneous heating for mixing a low-viscosity liquid or solid-liquid mixture. It's basic principle is to use the principle of same-sex repulsion and opposite attraction of magnetic fields to drive the magnetic stirrer placed in the container to rotate in a circular direction, thereby achieving the purpose of stirring liquids.


As one of the most common instruments in the laboratory, the magnetic stirrer has been used by almost every researcher, but how to standardize the operation to avoid safety accidents should also be fully understood.


Here is to share with you the common laboratory magnetic stirring non-standard operation:

1. Adjust the speed directly to the maximum speed to start the instrument

High-speed start instrument is easy to cause jump phenomenon but also prone to liquid splash, if it is corrosive liquid is easy to corrode the table and cause safety problems.

√Correct operation: it should start at a low speed, and slowly increase the speed to allow the instrument to run smoothly.

2. Start the temperature probe directly without good insertion

 If the temperature probe is not exposed, it will not properly monitor the experimental temperature all the time, which is likely to cause serious safety consequences.

√Correct operation: check the temperature probe before starting to ensure that the instrument is normal.

3. After turning off the instrument, quickly clean up the magnetic mixer to make room for other experiments to accidentally touch the disk surface

 The stirring experiment is usually accompanied by heating operation, and the disk surface is still in a high temperature state when the instrument is just turned off. If you touch it, you are re likely to get burned.

 √Correct operation: After the experiment, turn off the instrument for the disk cooling and then proceed to the next operation.

 

How to avoid the above errors to the greatest extent?

The answer must be to choose a suitable magnetic stirrer!√

 

INNOTEG WM-1 Magnetic Stirring to help you feel at mind experiment!

Highlight 1: Maximum rotation speed setting

The maximum speed can be adjusted by itself, to prevent non-standard operation to turn the speed out of the common speed range, to avoid jumping sputtering and other phenomena.

Highlight 2: Dual temperature sensor probe

Double PT1000 sensors are placed outside the sample area to control the temperature and protect all the way. Prevent safety problems caused by temperature probe damage.


Highlight 3: anti-corrosion silicone protective cover

Prevent the corrosive experimental samples from dropping into the instrument surface. A long time of use can also keep the instrument look new.

 

Highlight 4: disk surface temperature prompt function

After the heating is stopped, when the disk temperature exceeds 50℃, (even if the power is off, no power supply), the disk temperature overheating reminder will appear to protect the safety of the operator.
