Course 5 indicators, often known as integrating indicators, are built to respond to all crucial variables in the sterilization cycle.

Figure one. Decreasing order of resistance of microorganisms to disinfection and sterilization and the extent of disinfection or sterilization

Inside chemical indicators are positioned inside of each deal sterilized and confirm steam penetration into your deal and that all critical parameters were met.

Qualification tests is made of managing three consecutive cycles with negative BI effects. Consult with the sterilizer operator’s manual for qualification screening cycle needs.
