How to avoid common malfunctions of magnetic stirrers?

Avoidance and Solution Methods for Common Malfunctions of Magnetic Stirrers

1. If the stirrer jumps or does not stir during mixing, please cut off the power and check if the bottom of the beaker is flat and the position is correct. At the same time, please measure it. The current voltage used is between 220V ± 10V, otherwise the above situation will occur.

2. The heating time should generally not be too long, intermittent use can prolong the service life, and heating should not be done when not stirring.

3. Medium speed operation can work continuously for 8 hours, high-speed operation can work continuously for 4 hours, and prevent severe vibration during operation.

4. Electricity: The power socket should use a three hole safety socket and must be properly grounded.

5. The instrument should be kept clean and dry. It is strictly prohibited for the solution to flow into the machine to avoid damaging it. The power should be cut off when it is not working.

6. When using the instrument for the first time, check whether the accessories included in the instrument are complete, such as the mixer and power cord, by referring to the instrument manual.

When adjusting speed, it should be gradually adjusted from low speed to high speed,not advisableStart directly in high gear to prevent the agitator from being out of sync and causing jumping.

8. Cleaning of rotor: When stirring the solution with a magnetic stirrer, the rotor is easily dirty. When cleaning, first use neutralizing solution and then rinse with clean water. If the cleaning is not thorough, check if the outer white plastic film of the rotor is damaged. If it is damaged, it is recommended to replace it with a new mixer.

9. Selection of magnetic stirrer rotor: The size of the rotor ensures good stirring effect and matches the size of your beaker.

10. Method to extend the service life of magnetic stirrer: It is recommended to choose medium speed regulation when stirring. When using, switch from low speed to high speed after starting the power supply to prevent the agitator from jumping and affecting normal start-up, which may reduce the service life of the magnetic stirrer.
