Propper Manufacturing OK Sterilization Chemical Indicator Strip (250/BX)

• 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.
