There is described a water still (1) comprising a boiler assembly (5) and a condenser assembly (3) communicating by means (7) for removing droplets from vapour. The means comprise at least one jet, e.g. a plurality of jets (15, 17, 19, 21, 23, 25) radially disposed around a capped annulus (9), the jets capable of imparting to the droplets a spiralling motion, and urging the droplets to impinge on an interposed deflecting surface, e.g. a side wall (13) of the still (1). Stills (1) including a heatable distillate receiver (39), a gas vent (51, 53), a level detector (69), a boiler outlet valve (59) and an improved condenser (45) are also described. The stills described are useful for preparing water of low conductivity.

In an enclosed, walled water still for providing distilled water and having a lower water boiler chamber and an upper condensor chamber with a condensor coil, the improvement of providing distilled water with low conductivity, said improvement comprising: a cyclone liquid/vapor separator in the form of a capped annulus mounted between the water still walls and intermediate the lower water boiler chamber and the upper condensor chamber for removing droplets from vapor, the capped annulus having a plurality of jets for imparting a spiralling motion to droplets and vapor entering said annulus from the water boiler and urging the droplets to impinge on an interposed deflecting surface; a distillate receiver integrally formed on top of said cyclone liquid/vapor separator with the receiver bottom formed integrally with the top of said capped annulus and with the condensor coil mounted above the distillate receiver; and means enabling the vapor separated from the droplets to impinge on the condensor coil to form water collected in the bottom of the distillate receiver.
