A sterilization container, insert therefor, and systems are described, wherein at least one of the container or the insert therefor at the contact point between them is constructed of a conductive, non-corrosive material, most preferably stainless steel, while the bulk of the container or insert therefore is constructed of a non-conductive material, most preferably anodized aluminum. The container, insert, and whole systems are suitable for use in gas plasma sterilization procedures, but especially in those procedures that include a hydrogen peroxide gas plasma “express” cycle.
