The science of cryobiology is at the crossroads of physics and biology. It is this precise science that determines the conditions which permit the preservation of life and biological function of a variety of living systems at extreme low temperatures, e.g. -196°C.

Air Liquide Cryogenic Materiel Division develops, manufactures and commercials a comprehensive line of cryogenic freezers and equipment dedicated to the transportation and storage of biological products in nitrogen.

 Oxygen therapy aims to increase the oxygen fraction of the air breathed in by patients in spontaneous respiration in order to obtain or re-establish a normal level of oxygen in the bloodstream. CRYOPAL proposes a complete range of stationary and portable liquid oxygen tanks and accessories for treating people with breathing difficulties in their own homes by means of liquid oxygen therapy. Liquid oxygen offers patients optimal comfort of use and considerable autonomy since it only take up a limited space, thereby allowing patients to move about freely.
The oxygen supplied is completely pure (in the medical sense). This silent system does not need to be connected to an electrical power source.
