Frequently Asked Questions (FAQ)
How do I interpret the results of the biological indicator?
After incubation, a color change in the medium (typically from purple to yellow) indicates bacterial growth and a failed sterilization cycle. If the color remains unchanged, sterilization was successful.
Does this indicator require aseptic handling?
No, our biological indicators are designed for simple incubation without the need for a clean room or aseptic processing, making them easy to use in hospital environments.
Can I use the Steam indicator for EO sterilization?
No, each indicator is specifically calibrated for a specific sterilization method (Steam, EO, or H2O2) using different bacterial spores and chemical sensitivities. Please use the model corresponding to your equipment.
What is the shelf life of these biological indicators?
The quality guarantee period is three years from the date of manufacture when stored under recommended conditions.
Is the indicator label permanent?
The external label is removable, allowing you to easily peel it off and attach it to your sterilization logs or medical records for long-term documentation.
What is the standard incubation time for the EO version?
The standard incubation time for our EO (Ethylene Oxide) biological indicator is 24 hours to ensure accurate results.
