General description

The Sterikon® plus Bioindicator contains a nutrient broth, sugar, a pH indicator, and spores of a non-pathogenic organism, Geobacillus stearothermophilus ATCC 7953 (sporulation optimized) in a single ampoule. The spores are completely killed upon heating in compressed steam at a temperature of 121 ± 0.5°C (245 kPa), after 15 minutes. At lower temperatures or lower exposure times, a small number of spores can survive at and can grow upon incubation. Sterikon® ampoules are placed into the autoclave along with the batch to be autoclaved. The efficiency of the sterilization process is checked by the incubation of the ampoules. Red (or red-violet) color of the ampoule contents indicates no growth of Geobacillus stearothermophilus and adequate sterilization, whereas the yellow (or yellow-orange) color of the ampoule contents indicates growth and inadequate sterilization.

Application

Sterikon® plus Bioindicator System is used to monitor the effectiveness of the autoclaving by steam sterilization for 15 minutes at 121°C. It is suitable for checking the sterilization efficiency of the culture media products used for testing of pharmaceuticals (especially drugs in ampoule form), food and water samples, along with canned foods and other products to be autoclaved.
