1 Compatible: This is a heavy-duty silicone cover specially designed to be compatible for Anova. But it's also compatible with most sous-vide pots with an opening 2-" in diameter. Check to see 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 will fit the 10 1/2" size and any smaller. Added versatility to the type of container used in the sous-vide. Make sure 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: Helps maintain proper temperature and minimize evaporation. No more getting up in the middle of the night to fill a jar.5 Bonus: Silent water sloshing sound. Using a sous-vide lid allows you to preheat faster and reduce overall heating time during cooking.
