Abstract
A Bowie and Dick type prevacuum steam sterilization test pack for insertion into a sterilization chamber for indicating the presence of unacceptable levels of uncondensable gas comprises a housing, a heat sink and an indicator. The housing defines a single chamber having a large open end, a relatively small closed end opposite the open end, and a sidewall smoothly tapering from the open end to the closed end. The heat sink is disposed in the chamber and extends substantially from the open end to the closed end to define a path through which the steam travels from the open end toward the closed end, the path being adapted to provide sufficient exposure of the steam to the heat sink so that the steam condenses within the path, releasing any noncondensable gas associated with the steam, forcing the noncondensable gas so released toward and concentrating such noncondensable gas within the closed end. An indicator is disposed in the chamber adjacent the closed end for indicating the presence of noncondensable gas concentrated therein.
