An ANSI/AAMI/ISO 11140-1:2005 Class 5 Integrating Indicator for use in determining whether the sterilization process conditions were met inside each pack. Can be used in all 250-275°F sterilization cycles.
3M™ Comply™ Thermalog™ Steam Chemical Integrators consist of a paper wick and steam and temperature sensitive chemical contained in a paper/film and foil laminate envelope. Steam enters the permeable topside of the device -- the chemical melts and migrates along the paper wick; the distance or extent of migration depends on exposure to steam, time, and temperature. The migration is visible through a window marked UNSAFE or SAFE. The color should enter the SAFE window. If it does not, then the critical parameters of the steam sterilization process (time, temperature, and saturated steam) were not present.
Used in all 250-275°F/121-135°C steam sterilization cycles.
