Read-Out Time 7 sec

An optional visual pH color change confirmation could be made after 48 hours of incubation. If sterilization process has not been successful, culture medium will change to a greenish color first, and then to yellow during incubation at 60 °C, thus showing the presence of living spores. If sterilization process is successful culture medium will remain purple after the incubation process.

7-day readout is optional and not intended to be routinely performed; it is an initial validation of the 7-seconds readout. Fluorescence results may be compared to the 7-day visual reading.
NOTE: if 7-day readout is performed, a humidified environment will be required to avoid medium to dry out.

D-Value: Not lower than 1.5 minutes at 121 °C. Another D-value is informed at 132 °C and at 135 °C.

Z-Value is informed
