Abstract

1316808 Test pack for indicating the efficacy of a sterilisation process MINNESOTA MINING & MFG CO 4 June 1970 [5 June 1969; 8 May 1970] 27078/70 Heading B1X Apparatus to determine the efficacy of a sterilisation process comprises a translucent or transparent manually deformable outer container 10, which contains a predetermined number of viable micro-organisms and which has liquid impermeable and gas absorptive walls and whose end(s) is (are) closed by a gas transmissive, bacteria-impermeable closure(s) 22. A sealed, pressure openable inner container 18 contains nutrient for the micro-organisms: A detector material capable of undergoing a visable colour change in response to microorganism growth is housed within one of the containers 10, 18, e.g. on a water absorbent sheet 16, metal or glass beads. After sterilisation of the apparatus by means of, e.g. heat, radiation or by passing a gas through cap 29, the inner container 18 is broken, the apparatus incubated and any colour change noted.
