Self-Contained Biological Indicators consist of:
✅A plastic pipe and cap. The cap with a hole is placed on top of the pipe to allow the sterilizing agent to penetrate into the indicator. Between pipe and cap there is a filter paper which is used to avoid pollution.
✅ A crushable media ampule which contains modified culture medium with a pH indicator and fluorogenic substrates. The modified culture medium will change from the initial Purple color to Yellow in the presence of bacterial growth.
✅ An inoculated carrier of Geobacillus stearothermophilus ATCC 7953 is located at the bottom closed end of the pipe.
✅ The LBF060 Rapid Biological Indicator, when used with an automatic reader (incubation temperature 56-60°C), provides a fluorescence test result in a short period (60 minutes) with an accuracy of ≥97%. As an option the user can continue the incubation for 48 hours in order to confirm visually the stability or color change of the culture medium.
✅The label on the outside of the plastic pipe contains a Type 1 chemical indicator strip.
