摘要： A self contained biological indicator (A) determines an effectiveness of a microbial decontamination process. A dart (68) has a seal (80) engaged by rim (58) in detents (50C) in fins (36A-36F) of a cap (C). The dart has a cutting edge (76) aligned just above a foil seal (86) sealing a growth medium (F) in a medium housing (D). The dart has a chamber (72) in which challenge spores or other microorganisms on a paper disk (74) are housed. A microporous membrane (G) traps the challenge spores in the chamber while allowing a microbial decontamination fluid to flow through to contact the spores. The housing is lodged by a flange (56) in detents (50A) in fins (36A-36F). After the microbial decontamination process is complete, the cap is forced toward medium housing causing the rim and the flange to dislodge from their respective detents and lodge in detents (50B) resulting in the puncturing of the foil seal, the sealing of the dart within the medium housing and the immersion of the dart and the challenge spores into the growth medium.

摘要： A lid (10) of a countertop decontamination unit (A) is opened to gain access to a tray (12) for receiving items to be sterilized and a well (16) for receiving a two compartment powdered anti-microbial agent carrying cup (C). The cup includes an outer cup portion (50) and an inner cup portion (70) that have peripheral walls (52, 72) affixed together at flanges (54, 74). The outer cup portion (50) is closed at one end by a first detachable base (58). The inner cup portion (70) is closed by a second detachable base (78). The outer and inner cups (50, 70) define a first powdered reagent receiving chamber (56) therebetween. The inner cup defines a second chamber therein. A permeable sheet (100) is affixed to the inner cup portion flange (74) for ventedly sealing both chambers.
