Abstract: The disclosed process challenge device is a casing and a self-contained biological indicator operatively connected to the casing. The biological indicator has a housing with an open end and an interior space, a plurality of viable test microorganisms or an active enzyme in the housing, a sterilant pathway extending through the housing to the test microorganisms or the active enzyme, a detection reagent in the interior space, and an aqueous liquid in an openable container. The aqueous liquid is in selective communication with the viable test microorganisms or active enzyme. A first portion of the biological indicator has an open end and is disposed in the casing and a second portion of the self-contained biological indicator is disposed outside the casing. The second portion of the biological indicator comprises a part of the housing through which the aqueous liquid and detection reagent can be observed.
