Microbiological-scaled sterility controls
Abstract
Abstract A METHOD AND APPARATUS FOR DETERMINING THE EFFECTIVENESS OF A STERILIZING CYCLE BY PREPARING A PLURALITY FOR EXAMPLE SEVEN SPORE IMPREGNATED STRIPS OF FILTER PAPER SEALED IN GLASSINE ENVELOPES AND EXPOSING THE STRIPS TO THE STERILIZING CYCLE UNDER STUDY. EACH OF THE SEVEN STRIPS HAS A DIFFERENT SPORE POPULATION, E.G. 10**3, 10**4, 10*:5, 10**6, 10**7, 10**8, AND 10**9. THE STERILITY CONTROL IS EITHER EXPOSED DIRECTLY TO THE ACTIVE ELEMENTS OF THE STERILIZING PROCESS OR THE CONTROL IS PLACED IN THE LOAD OF MATERIALS TO BE STERILIZED. THE STRIPS ARE THEN REMOVED AND INCUBATED AND STUDIED. THE EFFECTIVENESS OF THE CYCLE CAN BE CONCLUDED FROM THE SPORE STRIP CONTAINING THE HIGHEST POPULATION ON WHICH THE ENTIRE POPULATION IS KILLED.
