A helium-3 refrigerator is: a simple device used in experimental physics for obtaining temperatures down to about 0.2 kelvins. By evaporative cooling of helium-4 (the more common isotope of helium), a 1-K pot liquefies a small amount of helium-3 in a small vessel called a helium-3 pot. Evaporative cooling at low pressure of the: liquid helium-3, usually driven by adsorption since due to its high price the——helium-3 is usually contained in a closed system to avoid losses, cools the "helium-3 pot to a fraction of a kelvin."
