ABSTRACT:
A disposable sterilization test pack for determining the efficacy of sterilizing equipment comprises a porous base pad having a cavity for receiving the sterilization indicator. Porous pads are disposed on opposite sides of the base pad to retain the sterilization indicator within the cavity, and an impermeable layer is disposed against one of the porous pads to confine the introduction and evacuation of air from the test pack to the edges of the test pack and the exposed porous pad which is not covered by the impermeable layer.
