- For monitoring Steam sterilization processes
- Control of Steam sterilization processes between 118°C and 138°C
- Type 5 Integrating Indicator
- Size: 52mm x 21mm
- Chemical Integrator consists of a paper wick and a steam and temperature sensitive chemical pellet contained in a paper/film/foil laminate
- The chemical pellet melts and migrates as a dark bar along the paper wick
- The migration is visible through a zone marked ACCEPT or REJECT, thus indicating whether sterilization conditions were met
- The extent of migration depends on steam quality, time, and temperature
- The ACCEPT result is reached when a theoretical spore population reaches its kill time, indicating integration condition has been reached
- This condition is calibrated with the kill time of 106 Geobacillus stearothermophilus spore population, calculated in BIER (Biological Indicator Evaluator Resistometer)
- Conditions: saturated steam at 121 °C, 128 °C, 135 °C.
