For steam sterilization cycles of 250°F (121°C) and 273°F (134°C)
OK® Strips are indicators that monitor all critical sterilization arameters: 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 equirements, the arrow and the K will change to become at least as dark as the reference color O forming the OK expression. The color response pattern may be used for sterilizer diagnostic evaluation.
The indicator dot printed on the distal end of the 8" strip permits a secure sterile presentation. Only if this dot is dark may sterile personnel handle the strip and the package contents. Without such assurance contamination of personnel becomes a real risk.
