Abstract
A high pressure cryogenic process for cooling a biological material, comprising the solidification of the biological material by a cryogenic fluid, wherein the solidification of the biological material is carried out at a cryogenic temperature at a pressure of at least 10 bar and the cryogenic fluid is present in an amount greater than 200 kg/m3.
Claims9
A high pressure cryogenic process for cooling a biological material, comprising a solidification of the biological material by a cryogenic fluid, introducing the biological material into a chamber containing the cryogenic fluid;
- and
- setting desired conditions of temperature, pressure and mass concentration quantity of cryogenic fluid within the chamber to a cryogenic temperature, so that the pressure inside the chamber is at least 10 bar and the mass concentration quantity of cryogenic fluid in the chamber is greater than 200 kg/m3, wherein the solidification of the biological material is carried out at a cryogenic temperature lower than 170 K, wherein the cryogenic fluid is nitrogen in liquid or in supercritical form.
