Cryobiology & dermatology

Air Liquide Healthcare is a supplier of medical-grade liquid nitrogen and medical-grade gaseous nitrogen. We bring over 100 years of proven experience to meet your medical gas needs.

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


Nitrogen gas is used

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


Liquid nitrogen is also 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.
