# OK Sterilization Chemical Indicator Strip

## Product Features

### Key Benefits
*   OK Strips are indicators that monitor all critical sterilization parameters: steam, time, and temperature.
*   In sterilization cycles, OK Strips guard against incomplete steam penetration, presence of noncondensing gases or excessive air, as well as from inadequate temperature or insufficient exposure time.
*   The pre-printed standard reference color permits rapid and certain visualization of the results.
*   If the sterilization conditions meet requirements, the arrow and the K will change to become at least as dark as the reference color O forming the OK expression.
*   There are 250 Class 4 sterilization chemical indicator strips in a box.
