The 3M™ Attest™ Steam Chemical Integrator, 1243A/1243B, is an ISO 11140-1:2014 Type 5 Integrating Indicator for use in determining whether the process conditions necessary for sterilization were met inside each pack. The Type 5 Chemical Integrator monitors time, temperature and steam and provides fast and easy to read results. As an internal pack control monitor for steam sterilization compliant with ISO 11140-1:2014, the 3M™ Attest™ Steam Chemical Integrator, 1243A/1243B, Type 5, uses moving front ink technology with vibrant “ACCEPT" (green) and “REJECT" (red) zones for easy interpretation within seconds that indicate whether the process conditions necessary for sterilization were met inside each pack. On the front of the integrator, you’ll find a scannable 2-D barcode containing the lot code and expiration date for entry into tracking systems. A red 3M logo on white background on the back of the integrator makes it easy to find when flipped over on the tray.
