Use Of Liquid Nitrogen

- Nov 23, 2017 -

Industrial use

In industrial production, the use of compressed liquid air fractionation method to obtain liquid nitrogen can be used as a deep refrigerant, because of its chemical inertia, can be directly in contact with biological tissue, immediately frozen without destroying biological activity, so can be used to:

(1) The rapid freezing and transportation of food, or the production of ice products;

(2) Research on low-temperature physics;

(3) Demonstrating the low temperature state in science education. Soft objects in liquid nitrogen will be brittle as glass at room temperature.

(4) Provide high-temperature superconductors to show the temperature required for superconductivity, such as yttrium barium copper oxide.

(5) can be used as refrigerant, to quickly freeze biological tissue, to prevent tissue damage.

(6) used in industrial nitrogen fertilizer.

(7) For chemical testing, such as bet specific surface area test method.

Biological and medical applications

(1) Except fire ant.

(2) The rapid freezing method can be used in surgical operation to help the bleeding and

To insert a 170-degree needle into a cancerous tissue to freeze the cancer.

To insert a 170-degree needle into a cancerous tissue to freeze the cancer.

The surface of the skin requires removal of the shallow layer.

(3) Preservation of living tissue, biological samples and storage of sperm and eggs;

(4) can be used as refrigerant, to quickly freeze biological tissue, to prevent tissue damage.

Frozen treatment

Liquid Nitrogen cryotherapy is a new technique in the field of modern therapeutics. Liquid Nitrogen cryotherapy is a comprehensive effect of frozen biology. The normal cells in the condition of extreme freezing can cause irreversible damage. It is through extreme freezing state, the ward cells quickly killed, so that the ward is normal recovery. Commonly used to treat wart, corns and skin diseases.

Cryotherapy is also used to treat breast cancer. ICECURE2012, an Israeli medical company, has developed a new technique for the treatment of breast cancer using cryotherapy, freezing and killing breast cancer cells in liquid nitrogen, a company that is conducting clinical trials. If successful, patients with breast cancer will be able to "resect" the tumor in the future without undergoing surgery.
