ABSTRACT:
A disposable test pack for monitoring the efficacy of steam or ethylene oxide sterilization cycles includes a fiber board housing for a bioligical indicator. The housing includes an outer tube and a shorter inner tube. The outer tube has upper and lower portions which define a seam or gap at their adjoining open ends. The inner tube extends past the seam and telescopes into the upper and lower portions. The seam and the close tolerance between the inner tube and the upper and lower portions of the outer tube provide a tortuous path for the entry of sterilant into the interior of the housing. The tortuous path has a moisture absorbent surface and is dimensioned to promote intimate contact between the sterilant and the absorbent surface. The exterior of the housing can be lined with foil to prevent sterilant from permeating the housing, thereby preventing entry of the steam by any path other than through the seam. A hole covered by an optionally removable tab is provided at the end of the upper portion of the outer tube for use in monitoring ethylene oxide sterilization cycles.
