The glass filter pump (7) is combined with a branch (23) for withdrawing cooling water and with valves (24, 25, 27) for the cooling water and the water leading to the jet nozzle into a unit (30). The vacuum regulator (18) is equipped with a temperature sensor (28) to be positioned in the upper part of the cooler (4). When the vaporisation chamber (5) is evacuated after the liquid mixture (2) to be distilled has been heated, the pressure is stored as a setpoint at which the temperature sensor (28) reacts to a temperature rise. <IMAGE>
