Key Features
-
Multi-Variable Monitoring: Engineered to monitor time and temperature, ensuring that the steam sterilization process has reached the necessary levels for successful decontamination.
-
Distinct Color Transition: Features a clear, high-contrast color change that is easy for clinical staff to interpret, reducing the risk of using non-sterile instruments.
-
Lead-Free & Eco-Friendly: Formulated without lead or heavy metals, making the strips safe for staff to handle and environmentally responsible for disposal.
-
Internal Monitoring: Designed to be placed inside each individual pack, pouch, or tray to verify that steam has penetrated the load effectively.
-
Perforated Design: The 4-inch strips are sized for convenience and can be used in a variety of small-to-medium instrument configurations.
Clinical Applications
-
Instrument Processing: An essential component of a comprehensive sterility assurance program in dental offices, surgical centers, and veterinary clinics.
-
Load Verification: Provides a record-keeping standard to prove that individual packs reached the required sterilization parameters.
-
Quality Control: Acts as an immediate safety check for clinicians before opening a sterile field.
⚠️ Usage Note: These are Type 4 indicators and do not replace the need for weekly biological indicator (spore) testing. They only indicate that the specific parameters for the strip were met, not that the load is guaranteed sterile.
⚠️ Storage: Store in a cool, dry place away from light and sterilization chemicals before use. Do not use after the expiration date printed on the box.
⚠️ Interpretation: If the color change is incomplete or remains blue, the contents of the pack must be considered non-sterile and re-processed.
