OK® Sterilization Chemical Indicator Strip Steam 4 Inch - Propper Manufacturing Mfr# 26410100

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 non-condensing 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
