Steam and EO integrator tape is designed to monitor exposure to steam or EO conditions.Which consists of yellow indicator stripes and pressure-sensitive adhesive. When the steam sterilization is completed, the color of the indicator strips will turn from yellow to dark brown or black. The complete color change occurs in 15 to 20 minutes at 121℃/250℉, in a gravity cycle, and in 6 minutes in both a132℃/270℉ gravity and vacuum-assisted cycle. 

In the meanwhile the chemical strips turn from pink to green after exposed to the EO sterilization process.
