Composite Contact & Manipulation Instruments - Ultra-light, non-stick, anodized aluminum. CCI and CMI anodized aluminum instruments are treated with the non-stick coating PTFE (polytetrafluoroethylene) to provide additional lubricity and protection against harsh solutions. Cleaning/Sterilizing Tips: Do not mix unlike metails in the same bag. Simply wipe off CMIs - do not expose to sollutions with pH above 8 or containing iodophors.
