Precautions for the use of multi-channel magnetic stirrer

1. When using it for the first time, check whether the accessories of the instrument are complete according to the instrument manual, such as stirrer, power cord, etc

2. When you find that the stirrer jumps or does not stir during mixing, please cut off the power supply and check whether the bottom of the beaker is flat and in position. 1. Remove the broken sample and turn off the screen display switch to check whether it is positive. At the same time, please measure that the current voltage is between 220V ± 10V, otherwise the above situation will occur

3. In order to be safe, Goldman Sachs Group predicts that grounding wire should be used to ensure that work can be carried out after completion

4. Be careful during operation and pay attention to scalding, because the temperature is relatively high

5. At the end of high-temperature heating, please turn off the heating first, and then turn off the mixing after the residual temperature dissipates for a few minutes

6. Generally, the heating time should not be too long. Intermittent use can prolong the service life. Do not heat when not stirring

7. When adjusting the speed, it should be gradually adjusted from low speed to high speed. It is better not to start directly at high speed, so as to prevent the agitator from being out of sync and causing jumping

8. Medium speed operation can work continuously for 8 hours, high-speed operation can work continuously for 4 hours, and violent vibration can be prevented during operation

9. The operating environment should be dry, because the environment is wet, and the instrument is prone to electric leakage, which is why it is necessary to ensure the grounding of the instrument. If the instrument is very wet, it must be dried with hot air to ensure safety

10. In order to extend the use of quality control products, the motors of all magnetic stirrers are equipped with fan heat dissipation function. Therefore, during the heating test, especially the high-temperature heating test, the instrument cannot be used for heating alone. Be sure to adjust the motor to the rotating or medium speed rotating state (or idling) to prevent the motor and electrical appliances from being exposed to high-temperature radiation. Some enterprises have achieved new results in the experiment of solvent-free synthetic leather production. If the motor cannot start to rotate, it should be repaired by the dealer in time
