What is the temperature of ultra-low temperature liquid nitrogen freezer?

Ultra-low temperature liquid nitrogen freezer is a special type of cold storage that uses liquid nitrogen as a cooling medium and is able to reduce the temperature to a very low level. Liquid nitrogen freezers are usually used to store special items, such as biological samples, medicines, food, etc., to ensure their quality and stability during long-term storage. The temperature range of ultra-low temperature liquid nitrogen freezers will be described below.

The temperature of an ultra-low temperature liquid nitrogen freezer can usually reach -150°C or even lower. Liquid nitrogen is an extremely low-temperature liquid with a boiling point of -196℃. By injecting liquid nitrogen into the cooler or cooling pipes inside the freezer, the temperature inside the freezer can be rapidly lowered and kept at ultra-low temperature.

Ultra-low temperature liquid nitrogen freezer has the following characteristics:

Low temperature stability: liquid nitrogen freezers can provide a very stable ultra-low temperature environment, ensuring that the temperature of the stored items is always kept within the required range.

Efficient Cooling: Liquid nitrogen has high cooling efficiency, which can quickly reduce the temperature inside the warehouse to the target temperature, suitable for items that need to be frozen quickly.

Water vapour and oxygen-free environment: liquid nitrogen in the liquid nitrogen freezer will absorb the surrounding heat when it evaporates, forming a water vapour and oxygen-free environment inside the freezer, which is conducive to preventing the oxidation and degradation of the articles.

High safety: Liquid nitrogen exists in liquid state in the freezer, which will not generate pressure and is relatively safe. However, care needs to be taken to avoid contact with the skin to avoid frostbite.

The temperature range of ultra-low temperature liquid nitrogen freezers is widely used in scientific research institutions, biomedicine, food industry and other fields. Different types of items may require different storage temperatures. When using an ultra-low temperature liquid nitrogen freezer, the appropriate temperature should be set according to the characteristics and requirements of the items.

Overall, ultra-low temperature liquid nitrogen freezers are able to provide extremely low temperatures and offer a reliable solution for long-term storage of special items. It plays an important role in ensuring the quality and stability of items and is widely used in scientific research and industrial fields.
