Compared with ordinary household refrigerators, the biggest difference is that ultra low temperature freezer can reach very low temperatures, such as -60°C, -86°C or even lower.  Just because of their ability to reach extremely low temperatures, we often use ultra-low temperature freezers in some special industries or purposes.

Application industries of ultra low temperature refrigerator:

1. Biological and physical research

Many scientific research projects, such as superconductors, biology, etc., need to be carried out at extremely low temperatures. Superconductors refer to some electrical conductors whose resistance suddenly approaches or even reaches zero at a special low temperature. Such electrical conductors require very low temperatures to show the properties of superconductors. The same is true for biology. Many biological studies also require low temperature environments.

2. Medicine

Research on the survival of microorganisms in a low temperature environment is one of the important topics in medicine. We can use low temperature to study the survival limit of some microorganisms, which can help fight diseases. In addition, some blood, vaccines, and medicines used in hospitals also need to be stored at low temperature.

3. Chemistry

Many chemical substances will have different special changes in different environments. For example, enzymes composed of proteins will undergo molecular structure changes and lose their special properties in low-temperature or high-temperature environments. Therefore, chemical research is also inseparable from ultra-low temperature refrigerators.

4. Pelagic fishery

Pelagic fishery is an industry at sea. Due to the long distance from the ground and the long fishing cycle, how to preserve the caught fish is an important part. At this time, it is necessary to use low temperature freezer to store the caught fish.
