ABSTRACT:
A process challenge device (PCD) for determining the effectiveness of a microbial deactivation process that uses a vaporous deactivating agent (e.g., vaporized hydrogen peroxide) as a deactivating agent. The PCD includes first and second layers that are joined together to form (1) a chamber dimensioned to receive a biological and/or chemical indicator, and (2) first and second conduits fluidly connecting the chamber with a region outside the PCD. Each conduit has one end in communication with the region outside the PCD and another end in communication with the chamber. A removable seal member seals the biological and/or chemical indicator inside the chamber.
