Abstract
Abstract Contiguous puncturable containers of water and ethylene oxide are provided as a unitary device to provide successive introduction and vaporization into a chamber in which there are contained objects to be sterilized. The containers comprising the unitary structure are opened in succession to provide necessary humidity followed by the introduction of ethylene oxide gas, where both substances are necessary for accomplishing effective sterilization.
