An optional pH color change confirmation can be observed after 48 hours of incubation. If the sterilization process fails, the culture medium will initially turn green and then yellow during incubation at 60°C, indicating the presence of viable spores. Successful sterilization will keep the culture medium purple after incubation. Please consult the usage instructions for cycle applicability in your region.

The 7-day readout is optional and not intended for routine use; it serves as an initial validation of the 20-minute result. Fluorescence outcomes can be compared with the 7-day visual results.
