Liquid Nitrogen Uses

- Feb 28, 2020-

Liquid nitrogen has many uses, mainly based on its cold temperature and low reactivity. Examples of common applications include:

  • The      freezing and transporting of food products

  • The      cryopreservation of biological samples, such as sperm, eggs, and animal      genetic samples

  • Use      as a coolant for superconductors, vacuum pumps, and other materials and equipment

  • Use      in cryotherapy to remove skin abnormalities

  • The      shielding of materials from oxygen exposure

  • The      quick freezing of water or pipes to allow work on them when valves are      unavailable

  • A      source of extremely dry nitrogen gas

  • The      branding of cattle

  • The      molecular gastronomy preparation of unusual foods and beverages

  • The      cooling of materials for easier machining or fracturing

  • Science      projects, including making liquid nitrogen ice cream, creating nitrogen      fog, and flash-freezing flowers and subsequently watching them shatter      when tapped onto a hard surface.
