Sterilization Biological Indicator

Biological indicators Incubator GKE, or spore tests, are employed to verify the validity of the sterilization processes of chemical gas autoclaves and saturated vapor (class N, S, and B cycles).

Initially, it is imperative to place a vial in the autoclave chamber, along with the necessary instruments, and initiate the sterilization process. Upon its conclusion, activate the vial and incubate it at 57.5°C for 24 hours. The test results are determined at the conclusion of the incubation period. A positive result is obtained if the vial remains blue/purple and does not change color. A negative result is obtained if the vial changes color to brown/yellow, indicating that the sterilization process was unsuccessful.
