Keys for using low-temperature coolant circulation pump

The low-temperature coolant circulation pump is an equipment that provides a low-temperature environment for experiments. It can be used with rotary evaporators, glass reactors, etc. to perform chemical reactions at low temperatures. The low-temperature coolant circulation pump, as a new type of low-temperature liquid circulation equipment, can provide better cooling effects.

Keys for using cryogenic cooling liquid circulator:

1. Liquid medium (pure water, alcohol, antifreeze solution, etc.) should be added into the tank before use. The liquid level of the medium should not cover the refrigeration coil in the tank and should be lower than the workbench;

2. The power supply power should be greater than the total power of the instrument, and the power supply must have a good "grounding" device;

3. Prevent acid and alkali substances from entering the tank and corroding the coil and liner;

4. The instrument should be placed in a dry and ventilated place, with no obstacles around it;

5. Always pay attention to the liquid level in the tank. When the liquid level is too low, add liquid medium in time;

6. When the working temperature of the low-temperature coolant circulating pump is low, be careful not to open the upper cover and keep your hands away from the tank to prevent frostbite;

7. After use, turn all switches off and cut off the power supply;

8. When the liquid is circulated externally, special attention should be paid to the firmness of the connection of the outlet pipe to prevent it from falling off to avoid leakage of liquid;

9. Regular cleaning should be done. If not used for a long time, the media in the tank should be emptied and wiped clean to keep the work surface and operation panel clean.

The low temperature cooling liquid circulating pump is a low-temperature liquid circulation equipment that adopts mechanical refrigeration. It has the function of providing low-temperature liquid and low-temperature water bath. Combined with rotary evaporator, vacuum freeze drying box, circulating water vacuum pump, magnetic stirrer and other instruments, it can carry out multi-functional chemical reaction operations at low temperature.
