ABSTRACT:
A method of sterilizing with a mixture of ethylene oxide gas and an inert gas which makes possible reuse of the ethylene oxide for an indefinite number of successive sterilization cycles. The gas mixture is refortified with ethylene oxide when necessary. A portion of it is periodically vented when the increasing proportion of air produces a mixture which approaches the region of flammability of the mixture and is replaced with the inert gas to reduce the proportion of air in the mixture.
