Abstract
A BIER vessel evaluates biological indicators for sterilization processes. By flowing gaseous sterilant, such as vaporized hydrogen peroxide, through a chamber (12) before, during, and after introducing the indicators, the indicators are instantaneously exposed to preselected steady state conditions, allowing accurate and reproducible evaluation of the indicator response. A door (32) to an opening (30) in the chamber opens for introducing the indicators to the chamber without appreciably disturbing the steady state conditions therein. After a preselected time, the biological indicators are removed and evaluated for remaining biological activity.
