How Sterilization Indicator Labels Work
Sterilization Method | Initial Color | Final Color | What It Confirms |
|---|---|---|---|
Steam Autoclave (121°C) | Yellow | Black | Exposure to steam, temperature, and time |
Steam Autoclave (134°C) | Yellow | Black | Exposure to steam, temperature, and time |
EtO (Ethylene Oxide) | Pink | Yellow | Exposure to EtO gas concentration, temperature, and time |
VHP (Vaporized H₂O₂) | Blue | Yellow | Exposure to VHP concentration and time |
💡 Note: Indicator labels confirm that the package has been exposed to sterilization conditions. They do not replace biological indicators for sterility assurance. Always follow your facility's sterilization validation protocol.
Applications
- CSSD (Central Sterile Services Department) – Affix to instrument packs, trays, and pouches before sterilization. Visual check after sterilization confirms processing.
- Operating rooms – Verify that surgical instrument packages have been sterilized before opening.
- Dental clinics – Indicator labels on dental instrument pouches and cassettes.
- Laboratories – Confirm sterilization of glassware, media, and waste before disposal.
- Pharmaceutical manufacturing – Process indicators on equipment and components.
- Veterinary clinics – Sterilization verification for surgical instruments.
Printer & Ribbon Compatibility
Printing options:
- Pre-printed – Indicator color and text pre-printed by us (recommended for high-volume users).
- Thermal transfer – Print variable data (dates, batch numbers) using resin ribbon.
Recommended ribbons:
- Resin ribbon – Required for printing on indicator labels. Wax/resin ribbons may not adhere to the indicator coating.
Compatible printers:
Printer settings suggestion:
- Darkness: 25–30%
- Speed: 2–4 inches per second (ips)
⚠️ Note: Always test a small batch with your specific sterilization method and printer settings before full production. Printing directly on the indicator area is not recommended – print on the white area only.
How to Choose the Right Sterilization Indicator Label
Step 1: Identify Your Sterilization Method
Method | Recommended Indicator | Color Change |
|---|---|---|
Steam autoclave (121°C/134°C) | Steam indicator label | Yellow → Black |
EtO | EtO indicator label | Pink → Yellow |
VHP | VHP indicator label | Blue → Yellow |
Dry heat | High-temp indicator label | Custom |
Step 2: Choose the Label Size
Application | Typical Size |
