Embodiment Construction
[0023]It should be understood that as used herein the term “vaporous” deactivating agents also includes “gaseous” deactivating agents. By way of example, and not limitation, the deactivating agents may include vaporized hydrogen peroxide, ozone, chlorine dioxide, and ethylene oxide.
[0024]Referring now to the drawings wherein the showings are for the purpose of illustrating a preferred embodiment of the invention only, and not for the purpose of limiting same, FIG. 3 shows a biological indicator (BI) 10 according to an embodiment of the present invention. BI 10 is generally comprised of a carrier 20 (best seen in FIG. 2); an inoculum 30 comprised of a plurality of microorganisms 38 suspended in a suspension medium 36; and an envelope 46. Inoculum 30 is prepared by suspending microorganisms 38 within suspension medium 36. Inoculum 30 is deposited onto carrier 20. Thereafter, carrier 20 is sealed within envelope 46. Each component of BI 10 is described in detail below.
