ABSTRACT:
A closure and container assembly biological sterility indicator having a container, a closure, test spores, growth and indicator media, and a frangible barrier for separating the growth medium from the test spores is shown. The closure is moveable in the container between open and closed positions. When in the open position, sterilant may flow into and out of the container via a tortuous pathway defined by the interior surface of the container or the exterior surface of the closure. The tortuous pathway may also include one or more openings in the wall of the closure. When the closure is in the closed position, the container is sealed. The sterility indicator may be assembled with the test spores impregnated on a spore strip which is placed in close proximity to the closure.
