Liquid Nitrogen

Liquid nitrogenis nitrogen that is cold enough to exist in liquid form. It is used for many cooling and cryogenic applications. Here are some liquid nitrogen facts and information about handling liquid nitrogen safely.Liquid nitrogen containers may accumulate oxygen which is condensed from the air. As the nitrogen evaporates, there is a risk of violent oxidation of organic matter.Sometimes liquid nitrogen is denoted as LN2, LN, or LIN.Liquid nitrogen has the UN number 1977.At normal pressure, liquid nitrogen boils at 77 K (−195.8°C or −320.4°F).

Liquid Nitrogen Uses
  • Freezing and transport of food products.
  • Cryopreservation of biological samples.
  • Coolant for superconductors, vacuum pumps, and other materials and equipment.
  • Cryotherapy to remove skin abnormalities.
  • Shielding materials from oxygen exposure.
  • Cooling materials for easier machining or fracturing.
