Nine points of use of low temperature coolant circulation pump

Nine points of use of low-temperature coolant circulating pump The low-temperature coolant circulating pump is a low-temperature liquid circulating equipment that adopts mechanical refrigeration, and 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 and low-temperature chemical reaction operations
.

So, what should be paid attention to when using it? Let’s find out with me below
.

1.
Before using the low-temperature coolant circulating pump, a liquid medium (pure water, alcohol, and antifreeze can also be added) should be added to the tank, and the liquid level of the medium should not exceed the cooling coil in the tank and be 20mm lower than the workbench; 2 、Power supply: 220V50Hz, the power of the power supply should be greater than the total power of the instrument, and the power supply must have a good "grounding" device; 3.
Avoid acid and alkali substances entering the tank to corrode the coil and the inner tank; 4.
The instrument should be placed in a dry and ventilated place 5.
Always pay attention to observe the liquid level in the tank.
When the liquid level is too low, liquid medium should be added in time; 6.
When the working temperature of the low-temperature coolant circulating pump is low, attention should be paid to Do not open the top cover, and do not put your hands into the tank to prevent frostbite; 7.
After use, turn off all switches to cut off the power supply; 9.
The instrument should be cleaned regularly.
If it is not used for a long time, the medium in the tank should be emptied and wiped clean to keep the work surface and operation panel tidy
.

 The above is the relevant introduction about the key points of the use of the low temperature coolant circulating pump.
I believe that everyone has a corresponding understanding of this after reading, and I hope it can help everyone
