Twindicator Perforated Sterilization Indicator
Twindicator is an indicator disigned for monitoring all critical parameters of steam sterilization cycles at 250 degrees F (134 degreesC). Twindicator adds extra flexibility in sterilization monitoring: each 8" strip is perforated to allow for two 4" strips. The color change is easily observed on both 8" and 4" strips and indicates "PASS" when it turns uniformly black on the entire length of the strips.
