Abstract
Dilution refrigerator equipment, which includes a vacuum vessel with its connections, a dilution refrigerator, made essentially completely of plastic set inside it and supported from a metallic pumping tube, includes an upper still and a lower mixing chamber and a heat exchanger connecting them. The pumping tube is connected to the still of the dilution refrigerator. The tube connection of the still includes an intermediate piece, separating the metallic pumping tube from the plastic structure of the still, which is made from a mixture of plastic and metal powder, to accommodate the greatly deviating thermal expansions of the connection components to one another.
