ABSTRACT:
The present invention is directed to sterility indicators of the self-contained biological type and provides a device that assures direct impingement of the sterilant onto the microproorganisms. In this manner, the sterilant exposure conditions experienced by the test organisms reflects the exposure conditions to which the articles in the sterilizer are subjected. The device of the invention provides that the microorganisms are not directly contiguous with the ampule containing the aqueous nutrient medium.
