A Dewar tank is a type of vacuum flask that is used to store cryogenic liquids, such as liquid nitrogen. The tank is made of two concentric vessels, with the inner vessel containing the liquid nitrogen. The space between the two vessels is evacuated, which creates a vacuum. The vacuum prevents heat from entering the inner vessel, which helps to keep the liquid nitrogen cold.
