Abstract:

A SCBI useful in ambient air pressure systems is disclosed. The SCBI includes a body which serves as the culture tube, a glass media ampoule, an inoculated stainless steel disc positioned on the top of the glass media ampoule so that the spores are close to the top/opening of the SCBI, filter paper on the top of the body and overlying the disc, and a cap.
