ABSTRACT:
A sterilization indicator for testing the effectiveness of a sterilization process and a sterilization process using such an indicator are described. The indicator comprises a first compartment having at least one open end; a gas-permeable, bacteria-impermeable closure covering said open end; said first compartment containing a number of viable microorganisms that are resistant to a related sterilization process; a second compartment moveable with respect to said first compartment; said second compartment having a predetermined quantity of nutrient medium for promoting the growth of said microorganisms; separation means for sealing the nutrient medium in said second compartment; communications means for providing communication between said first compartment and said second compartment when it is desired to contact said microorganisms with said nutrient medium; and a detector composition contained in one of said compartments that is capable of undergoing a detectable change in response to the growth of said microorganisms.
