Ultra-low temperature refers to a temperature lower than low temperature. In physics, it refers to the temperature of liquid air below -263 degrees Celsius, and ultra-low temperature refrigerators are a kind of equipment manufactured using ultra-low temperature technology. In fact, the so-called ultra-low temperature refrigerator is usually referred to as ultra-low temperature storage box, ultra-low temperature freezer and ultra-low temperature storage box. The following manufacturers of ultra-low temperature refrigerators, low temperature refrigerators and low temperature freezers will talk about the use and precautions for the use of ultra-low temperature refrigerators.

In fact, ultra-low temperature is often used in factory laboratories, scientific research institutes and other places to preserve experimental products and test product performance. During this period, ultra-low temperature refrigerators at minus 60 degrees Celsius can be used to preserve tuna, plasma, biological materials, vaccines and reagents, and can also be used. Low temperature experiments on electronic devices and special materials.

Ultra-low temperature refrigerators at minus 80 degrees Celsius generally use low temperature to preserve biological products, chemical reagents, plasma, vaccines, bacteria and biological samples. As for ultra-low temperature refrigerators at minus 105 to 150 degrees Celsius, they are suitable for scientific research institutes, metal processing, bioengineering, blood stations, hospitals, health and epidemic prevention systems, university laboratories and military enterprises.

It is not suitable to freeze strong acid or corrosive things inside the ultra-low temperature refrigerator. When the refrigerator starts to operate, it is necessary to ensure that the power supply voltage of the refrigerator is around 220V. In the event of a power outage, the power switch and battery switch behind the refrigerator need to be closed, and the switch should be turned on first when the power supply is re-supplied. In summer, you need to adjust the temperature of the refrigerator to about minus 70 degrees Celsius, not too low. Keep good indoor ventilation and heat dissipation, and pay attention that the temperature of the surrounding environment should not exceed 30 degrees Celsius.
