Abstract
A biological sterility indicator for submerging in water after sterilizing by a sterilizing medium comprises a sealed semi-permeable envelope containing a quantity of a test organism, said envelope being permeable to the sterilizing medium and to water but impermeable to the test organism and to bacteria in gas and liquid. A water-soluble growth medium may be sealed within said envelope for metabolizing by said test organism, or it may be outside said envelope and permeate therethrough, after sterilization. The envelope is preferably translucent and made of a semipermeable plastic composition. A dye, responsive to the presence of metabolizing bacteria of said test organism by a colour change, for indicating sterility may also be sealed in said envelope. In operation, the said envelope containing said test organism is subjected to a sterilizing medium for a sterilizing period, and is then submerged in water, for a test period, while in the presence of a water-soluble growth medium. Specified sterilizing media are steam, dry heat, boiling water, radiation, ethylene oxide, propylene oxide and methyl bromide.
