External controls

Chemical indicators of pass/fail control are used to differentiate the sterilization packs externally and biological indicators for verifying of bioburden elimination from its medical devices. 

Type 1. Pass/fail indicators

They are used externally on the wrapped materials  to indicate that they have been exposed to the sterilization process. They allow an easy identification of the material which has been processed and the one which hasn’t. As they do not react to all critical process variables, they do not show the attainment of the conditions required for sterilization. 

Type 2

Chemical indicators of high sensitivity for pass/fail control.

Biological indicators

Biological indicators have Geobacillus stearothermophilus and Bacillus atropheaus spores. The spores are the most resistant forms of life on the planet and allow to test sterilization processes through the simulation of a bioburden with a population of microorganisms and a specific resistance to different sterilization systems.

  • Envelopes of dry spore strips
  • Self-contained colorimetric (48 and 24 hours)
  • Self-contained fluorimetric (4 hours, 3 hours,1 hour, 30 minutes)
