Zusammenfassung:	A system and method for sterilizing a cryogen is provided. In the disclosed embodiment a liquid cryogen is first vaporized and subsequently compressed prior to undergoing sterilization using biological filters. The compressed, sterilized cryogen vapor is then pre-cooled, preferably with the cryogen being vaporized, to produce a partially condensed, cool, sterile cryogen stream and then further condensed using the liquid cryogen to produce a sterilized liquid cryogen.
