Propper OK® Steam Sterilization Strips


These indicators monitor steam, time, and temperature for sterilization cycles of 121°C (250°F) and 134°C (272°F). The pre-printed standard reference colour permits rapid visualization of the results, with an arrow and a letter K darkening in colour to match the reference letter O if sterilization meets requirements. An indicator dot imprint on the distal end of the strip permits a secure sterile presentation.
