A refrigerator capable of operating both in evaporation and dilution modes is described. The refrigerator provides preliminary cooling of investigated samples down to a starting temperature of about 0.3 K and permits the location of samples directly in the mixing chamber as well as their replacement
A 3He/4He dilution refrigerator is described where the instreaming 3He is precooled and liquefied by a counterflow heat exchanger which makes use of the enthalpy of the cold 3He gas pumped out of the still, and by subsequent Joule-Thomson expansion. This condenser replaces the usual 4He condenser.
