ABSTRACT:
Methods for sterilization wherein air is purged from the load to be sterilized prior to the addition of the sterilant and wherein residue chemical sterilants, such as ethylene oxide, are purged post-sterilization by introducing air and steam at pressures which cause the steam to condense on the interstices of the load and then vaporize to provide a carrier for trapped air (prior to sterilization) and residue chemical sterilant (post-sterilization).
