Moving front chemical integrator to monitor Steam sterilization processes between 118 and 138 °C. ISO 11140-1 Type 5.

• Type 5 Integrating Indicator (according to ISO 11140-1)
• Size: 52×21 mm
• 100% free of toxic heavy metals
• Shelf-life: 5 years

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, 128 and 135 °C.

Storage conditions:
Temperature: 10 to 30 °C, RH: 30 to 80%, keep out of direct light.
