ProChek ID Indicator Strips (SM4340) are internal Class 1 indicators reacting to steam moisture and heat. The ink changes from white to dark brown/black in steam or medium brown in chemical vapor. This product meets the CDC and AAMI ST79 guidelines for an internal chemical indicator to be used inside pouches, cassettes and packs to verify penetration of heat and steam inside the package.
ProChek S Steam Sterilization Integrators (TSI440) are Class 4 multi-parameter internal chemical monitors. The term “integrator” means the special chemical ink changes completely from yellow to blue/purple as it reacts to steam and heat over a time period that is near the parameters required to kill spores. This level of internal chemical monitor provides a higher level of assurance for surgery packs and instrument cassettes.
