Though sterilization methods have made a great improvement in terms of quality; the process monitoring ones are imposing costs to assure instrument long lasting sterility.
Indicator monitoring and traceability of sterilization processes are the requirements of medical-grade instruments both international and local rules. Moreover, healthcare centers shall observe these rules. Credentials and monitoring of sterilization processes are performed based on parametric, chemical and/or biological tests.
The Mini-Bio-Plus (SCBI) bolted biological indicator has got a plastic vial including spore plate and ampule to grow and indicate internal average pH. It is applied in routine monitoring and evaluation of most sterilization processes disregarding reference to microbiological labs. Caps are various in colors to distinguish type and application. In compliance with EN ISO 11138-1, Stereothermopholious steam sterilization on the spore population of 105 & 106 on medical carriers.
Hydrogen Peroxide (Plasma) Biological Indicator
Not only spore population and type but also applied carrier material are dependents of biological indicators resistance against plasma sterilization processes.
Ethylene Oxide Biological Indicator
This indicator is provided with spores 106 population on paper carrier in compliance with EN ISO 11138-2.
Rest of details on the indicator efficiency is as follows:
| 60% rel. humidity | 600mg/l EO | 54˚C | 25min | Kill |
| 60% rel. humidity | 600mg/l EO | 30˚C | 50min | Survival |
