A dilution refrigerator, the combination comprising an electrostatic mixing chamber containing 3He-rich and 4He-rich phases subject to separation in response to electrostatic force application, the chamber having an outlet for 3He that has passed through an interface between those two liquid phases to produce cooling; a still connected with the mixing chamber to receive 3He therefrom, the still having an outlet for 3He; two adsorption pumps connected with said still outlet to receive 3He vapor, alternately, there being a valve or valve system connected with each pump; heater structure associated with the pumps to cause 3He desorption by the pumps; a condenser-collector connected with the valves to receive desorbed 3He, 3He liquid being held at a flow path outlet from the condenser-collector; and a heat exchanger connected in a flow path from the condenser-collector back to the mixing chamber.
