Self Contained Spore Ampoules Steam

REDUCED - Due to short shelf life (Expiry date 08/20) Spore Ampoules for Steam Sterilisation Designed for monitoring Steam sterilisation processes at temperatures between 121°C and 135°C. The device consists of a glass ampoule containing spores of the non-pathogenic microorganism Geobacillus stearothermophilus ATCC 7953. The culture medium has been specifically designed to change its colour when microbial growth occurs. The spore population contained in the biological indicator is killed after an efficient steam sterilisation cycle. At lower temperatures or lower exposure times, some spores may survive and thus might be capable of growing. This growth can be detected by the indicator medium which turns from violet to yellow after 48 hours of incubation at 60°C. Conversely, if the sterilisation process has been effective, there is no microbial growth and the ampoule medium maintains its original color. Spore: Geobacillus stearothermophilus (ATCC 7953). in a 106 population.
