Nitrogen (N2)

Medical nitrogen in liquid and gaseous form for cryobiology & dermatology applications.

or more information

We are Canada’s leading supplier of medical liquid nitrogen and medical gaseous nitrogen for cryobiology and dermatology applications.

Medical applications

Nitrogen gas is neutral and colourless, and does not sustain life. Nitrogen is mainly found in the atmosphere where it accounts for about 78% of the air we breathe.

Liquid nitrogen is essential for cryobiology - the preservation of biological substances. At extremely low temperature (-196°C) liquid nitrogen is used to preserve blood, sperm, embryos, bone marrow and other biological samples without diminishing their intrinsic qualities.

In dermatology, nitrogen is used for cryosurgery and cryotherapy, enabling the treatment of cutaneous micro-trauma.

Nitrogen gas is also used in healthcare:

  • As a drive for medical tools and equipment
  • As a zero and balance gas for analysis in breathable gas mixtures
