After exposure to sterilant, incubate strips at 55-60°C. Bacillus atrophaeus* – For use in Ethylene Oxide (600 mg/L), Dry Heat Sterilization (D-value calculated at 160°C), and formaldehyde fumigation. After exposure to sterilant, incubate strips at 30-35°C. Bacillus pumilus* – Used for validation of irradiation sterilization processes. After exposure to sterilant, incubate strips at 30-35°C. Combined Species Spore Strips – G. stearothermophilus* (105) and B. atrophaeus* (106) on each strip. For use in Steam, EO, Dry Heat or Chemiclave® sterilizers.
