Beschreibung
Zusammenfassung:	A sample holding device (30) for a dilution refrigerator having a still (16), a mixing chamber (22), and a heat exchanger (26) connected between the still and mixing chamber whereby coolant flows from the still to the mixing chamber and from the mixing chamber to the still through respective first and second adjacent paths in the heat exchanger and wherein the mixing chamber has a tubular portion (27), the sample holding device comprising a tube for insertion in the tubular portion of the mixing chamber and having means (34) for holding a sample within the tubular portion, the tube having an aperture (36) adjacent the sample holding means communicating in use between the interior of the tube and the interior of the tubular portion and another aperture (37) positioned in use to communicate between the interior of the tube and the second path in the heat exchanger.
