Includes: 1 - Sterilization Silicone Mats with Raised Fingers for Sterilization Trays & Autoclave Boxes. Size: 7" L X 5.5" W ( 177 MM X 140MM X 20MM ). Cushioning: The silicone mat provides a soft layer between the instruments and the metal tray, preventing scratches and damage. Separation: The fingers keep instruments separated, avoiding them from touching each other and potentially transferring contaminants. Airflow: The space between the fingers allows for better air circulation during the sterilization process, promoting even drying and reducing the risk of moisture build-up. Medical Grade: These mats are made from medical-grade silicone, which is non-toxic and can withstand high temperatures used in sterilization methods like autoclaving.
