Biological Indicators



Biological indicators incubator, or spore tests, are used to check the validity of the sterilization processes of saturated vapor (class N, S and B cycles) and chemical gas autoclaves.

First of all it is necessary put a vial in autoclave chamber, with instruments, and start the sterilization process. When it ends, activate the vial and incubate it at 57.5°C for 24 hours. At the end of the incubation the test gives the result: if the vial does not change color and remain blue/purple the result is positive, if it changes the color in brown/yellow the result is negative (that means the sterilization process failed).

The correct test procedure previews the activation of a second new vial, without putting it in autoclave during the sterilization process. This vial has to be incubate with the previous one, at 57.5°C for 24 hours. At the end of the cycle it has to change color in brown/yellow, pointing out the suitability of the vials set.

Biological indicators complies with UNI EN ISO 113 8-1 +3.
