Includes: Set of 3 Sterilization Silicone Mats with Raised Fingers for Sterilization Trays & Autoclave Boxes. Sizes: (1) 9.5" L X 5.75"W ( 241MM X 146MM X 20MM ) + (1) 8.25" L X 5"W ( 209MM X 127MM X 20MM ) + (1) 6"L X 3.5" ( 152MM X 88MM 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.
