Product description - BT31

The Bionova® BT31 Biological Indicator is designed for the control of Dry Heat sterilization processes. It is compatible with extremely high temperatures generated during depyrogenation cycles and sterilization processes in ovens and dry heat tunnels. The contents of the ampoule should be incubated in the Bionova® MC1030-2 culture medium tube or a culture medium suitable for the growth of Bacillus atrophaeus ATCC 9372. If the sterilization process was unsuccessful, the indicator medium will change from blue to yellow after incubation at 37±2 °C, thus indicating the presence of living spores. If the sterilization process was successful, the indicator medium will remain blue, being the final reading taken after 72 hours of the indicator’s incubation at 37±2 °C.
