3M Chemical Indicators for Ethylene Oxide and Steam Sterilization Processes

3M indicators give you real-time information regarding your sterilization processes. 3M chemical indicators comply with pertinent industry standards such as:

• ANSI/AAMI ST60
• ISO 11140, Part 1
• EN 867, Part 1

Process Indicators (Class 1)

• Demonstrate that the unit has been exposed to the sterilization process
• Distinguish between processed and unprocessed units

Mulit-parameter Indicators (Class 4)

• React to two or more critical parameters of the sterilization process
• Ideal for routine use where additional process information is required

Integrating Indicators (Class 5)

• React to all critical parameters over a specified range of sterilization cycles
• Values based on inactivation of Bacillus atrophaeus (Bacillus subtilis var. niger) spores for EO and Geobacillus stearothermophilus (Bacillus stearothermophilus) spores for steam
