Cryopreservation

Nitrogen inhibits microbial growth and prevents food from spoiling. Nitrogen can inhibit the enzyme activity in food and maintain the original nutritional composition and color of food. Because nitrogen protects the surface of food from burning, it can greatly reduce cooking time. And because nitrogen can effectively inhibit the growth of microorganisms, it can make packaged food last longer.

                    Bioengineering

Liquid nitrogen is used for cryopreservation and storage of biological samples, such as cells, sera, plasma, antibodies, tissues, etc. Used to prepare biomolecules such as proteins, nucleic acids, peptides and complexes. For the preparation of biomaterials such as microspheres, microcapsules and microphagocytes. Used to prepare antibody and its marker. Used for high speed freeze drying and other chemical reactions.

                    Gas separation

Liquid nitrogen can be used for gas separation, mainly in industrial applications such as air separation, natural gas separation, liquefied gas separation, gasoline hydrogenation and olefin cracking.

                    Coolant

Liquid nitrogen is an excellent coolant that can be used to cool a variety of machines and equipment.The main uses of liquid nitrogen as coolant are: for frozen food, such as meat, fish, vegetables, etc.; Used for low temperature experiments in chemistry laboratory; Low temperature manufacturing for special industrial processes; For the preservation of blood and other biological samples; Used for cooling or cooling general articles.
