Both types of indicator strips are designed to monitor exposure to steam or EO conditions in a pack. Sterigage strips provide a visual accept/reject readout (moving front), while Comply strips show a colour change to validate that the sterilant has penetrated to the point of placement in the pack and confirm that sufficient exposure conditions have occurred.
