Abstract: A system for producing cryogenic sterile nitrogen wherein liquid nitrogen is first vaporized and subsequently heated prior to undergoing sterilization, the warm sterilized nitrogen vapor is cooled to effect the vaporization of the liquid nitrogen, and the resulting cooled sterilized nitrogen is condensed to produce the product cryogenic sterile nitrogen. The system may be used to produce other cryogenic sterile cryogens also.
