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