- 1251D01 and 1251D05 detect the presence of Bacillus stearothermophilus spores
- 1251D07 detects the presence of Bacillus subtilis spores
1251D01 indicators are designed for monitoring 270°F (132°C) gravity steam sterilization processes. Detection media will turn yellow in the event of a sterilization process failure. The final readout of a negative result (media remains purple) is made after 24 hours of incubation.
1251D05 indicators are designed for monitoring steam sterilization processes. Detection media will turn yellow in the event of a sterilization process failure. The final readout of a negative result (media remains purple) is made after 48 hours of incubation.
1251D07 indicators are designed for monitoring ethylene oxide (EO) sterilization processes. Detection media will turn yellow in the event of a sterilization process failure. The final readout of a negative result (media remains green) is made after 48 hours of incubation.
