nitrogen gas compressed under great pressure until it liquefies. If released from pressure, it evaporates rapidly, freezing whatever surface from which it evaporates.
Nitrogen in a liquid state. Liquid nitrogen is supercool -- about 200 degrees Celsius (320 degrees Fahrenheit ) below zero -- and is used for cryopreservation , cryosurgery , and cryomedicine. See the entire definition of Liquid nitrogen
nitrogen gas that has been cooled to the liquid state (-196°C) and used to cool and store cells in a frozen state
freezing agent used in most cryosurgical procedures of the prostate and kidney.
liquid form of nitrogen gas (-195 degrees Celsius) that is used to treat various skin lesions in cryosurgery
The dangerous tissue killing liquid form of the colorless tasteless odorless element that as a diatomic gas is relatively inert.
the environment in which cryopreserved specimens are stored and shipped. The liquid phase of nitrogen is -196°C. Cryopreserved specimens are stored at this temperature in the laboratory. The vapor phase of nitrogen has a slightly higher temperature. Shipping tanks used to deliver specimens maintain vapor temperature and the vapor phase facilitates shipping.
