Biological Indicator

Product Details:

•             Biological Indicators (BIs) are the main alternative to ensure the effectiveness of the sterilization processes. They are considered the highest level of sterility assurance because they actually test the sterilizer ability to kill specific strains of highly resistant organisms. Microorganisms widely recognized as suitable for BIs are bacterial spores because they are significantly more resistant than normal micro flora.

•             Geobacillus stearothermophilus spores demonstrate a high resistance toward steam, formaldehyde and vaporized/plasma hydrogen peroxide, they’re used in biological indicators that monitor these sterilization processes, while BIs with Bacillus atrophaeus are recommended for ethylene oxide and dry heat applications. Bacillus subtilis and Bacillus pumilus are used for controlling steam sterilization process at low temperature (110- 121°C) and gamma irradiation sterilization processes respectively
