1. Compatibility: This is a heavy-duty silicone cover specially designed to be compatible with Anova. It can also be compatible with most sous-vide pots having an opening 2" in diameter. It is recommended to check if it fits your cookware before ordering. 2. For a standard 10 1/2" pan: The lid is placed slightly forward on one side without any gap, so it may fit the 10 1/2" size and smaller ones. It adds some versatility to the type of container used in the sous-vide. It is advisable to measure your pan before buying. 3. Adequate seal: Made of thick soft silicone, it is heavy enough to lie flat on top of the pan and maintain a good seal, even if the pan is a few inches smaller in diameter. 4. Great for long-term cooking: It can help maintain proper temperature and minimize evaporation. You don't need to get up in the middle of the night to fill a jar. 5. Bonus: It can reduce the sound of water sloshing. Using a sous-vide lid allows for faster preheating and can reduce the overall heating time during cooking. 1*Silicone Sous Vide Lid
