The inventive device for distilling a medium comprises at least one reservoir (11, 51) or accommodating the medium (15, 55) to be distilled, a heating element (12, 52) for vaporizing the medium (55), and comprises at least one collecting vessel (20, 60), which is situated downstream and which is provided with a cooling element for condensing the produced distillation vapor. In addition, a pipe (19, 59) or the like is provided on the top side of the reservoir (11, 51). Said pipe leads into the collecting vessel (20, 60) and connects the vapor space (14, 54) located inside the reservoir (51) to that which is located inside the collecting vessel (20, 60). To this end, means are provided, which, for the most part, completely remove foreign gases from the vapor spaces (14, 24; 54, 64) before or at the beginning of the distillation process. At least one vacuum pump or a scrubbing device is provided as said means, with which the foreign gases in the vapor spaces (14, 24; 54, 64) can he removed by suction or scrubbing. This enables optimal conditions to be attained with regard to the energy budget and to the functioning of the device.
