Note: these are 20mm balls. Several vendors incorrectly claim these balls have a diameter of 25mm!
These insulating balls significantly reduce evaporation and heat loss when using a sous-vide circulator in a water bath reservoir without a lid. We highly recommend using these sous-vide insulation balls (also known as floating balls) if you're cooking without an insulated or sealed container. When the entire surface of the reservoir is covered with these balls, heat loss and evaporation are greatly reduced. Additionally, odors and light exposure are minimized. This quantity of sous-vide insulation balls is sufficient for approximately 30 x 30 cm or GN 1/2 size containers.
