ABSTRACT:
A device for indicating the presence of unacceptable levels of noncondensable gas, such as air, in a stream sterilization chamber. The device includes an insulated heat sink having an upper end and a lower end. The upper end of the heat sink is in such open communication with the sterilization chamber that the steam enters the heat sink. The device also includes a chamber proximate the lower end of the heat sink. The heat sink defines a path through which the steam travels from the upper end toward the chamber. The path is 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 and forcing it toward the chamber. The chamber includes means for indicating the presence of noncondensable gas accumulated therein. The device also includes means for preventing the condensate from effecting the indicating means.
