Abstract

A test pack for testing the adequacy of air removal in a prevacuum sterilizer. The test pack including a first plurality of planar sheets of substantially porous material disposed to form a stack; a second plurality of planar sheets of substantially porous material disposed to form a stack; an indicator adapted to provide an indication of the removal of air within the test pack and the replacement of the air by sterilizing gas; the indicator being disposed between the first and second pluralities of planar sheets; a tray formed of a gas inhibiting material, the tray having a base coextensive and aligned with an exposed side of one of the first and second pluralities of sheets and four side walls transverse to the base together substantially covering the exposed edges of the first and second pluralities of sheets having the indicator sandwiched between the first and second pluralities of sheets; the tray and the first and second pluralities of sheets with the indicator sheet disposed therebetween defining an assembly, the tray being open on one side opposite the base such that a surface of one of the first and second pluralities of sheets is not covered; and an organizer disposed all about the periphery of the assembly to maintain the sheets and the tray in a predetermined spatial relationship while permitting the passage of sterilizing gas and air to and from the assembly.
