Liquid nitrogen freezer is a kind of low-temperature cooling equipment that uses liquid nitrogen (LN2) as the refrigeration medium, and its application range is wide, mainly including the following aspects:
Medical field
The application of liquid nitrogen freezer in the medical field is mainly liquid nitrogen cryotherapy. This treatment achieves the purpose of treatment by using cryogenic freezing at -196°C to
destroy the diseased tissue, causing it to die and fall off. It is commonly used to treat various skin diseases, such as flat warts, molluscum contagiosum, various hemangiomas, keloids, etc., and can also be used for the treatment of diseases such as gynecology, ophthalmology, and ENT.
Food industry
Liquid nitrogen freezers are used in the food industry for food refrigeration, quick freezing, preservation, etc., such as fresh ingredients, pastries, etc. The low temperature properties of liquid nitrogen allow food to be quickly frozen to very low temperatures, preserving its freshness and taste.
Pharmaceutical industry
In the pharmaceutical industry, liquid nitrogen freezers are used to prepare medicines, vaccines, cells, etc., to ensure the purity and activity of products. The low temperature environment of liquid nitrogen can maintain the stability of biological samples and pharmaceutical products for a long time.
Scientific research experiments:
In the field of scientific research, liquid nitrogen freezers are used for experiments such as cryopreservation and separation of substances, such as cryo-EM and gel staining. These experiments require a cryogenic environment to maintain the stability and viability of the sample.
Semiconductor industry: Liquid nitrogen freezers also play an important role in the semiconductor manufacturing process. It is used in the low-temperature environment of the manufacturing process to ensure the stability and performance of semiconductor devices.
In addition, liquid nitrogen freezers are also widely used in other fields such as environmental protection, biological industry, and agriculture. It works by injecting liquid nitrogen into a heat pipe, through which the low temperature of nitrogen is transferred to the cooled object, so that its temperature decreases rapidly. The main advantages of liquid nitrogen freezers are fast speed, obvious refrigeration effect, and high efficiency and energy saving.
