ABSTRACT:
Apparatus for indicating whether the contents of a container have been sterilized during a sterilization process including a first member having a portion for coacting with the sterilization agent to indicate the sterility of the contents of the container. A second member is adapted to extend into the interior of the container to be sterilized and receive and releasably engage the first member so that said first member can be positioned within the interior of the container to be sterilized during the sterilization process and so that the first member can be placed in and withdrawn from the second member without exposing the contents of the container to the surrounding environment or the operator to the contents of the container. At least a portion of the second member is selectively permeable to the sterilization agent so that the sterilization agent can come in contact with the coacting portion of the first member and yet prevent the coacting portion from being contaminated if the contents of the container have been incompletely sterilized.
