Abstract

A still for the distillation of water or other liquids, the still having a boiling chamber with a heater, a vapor condenser chamber, and a vapor separator chamber all supported by a frame having a catch basin below the chambers and a distilled liquid sump below the catch basin into which the condenser discharges. The chambers telescopically plug together in position on the frame and are easily separated and knocked-down for cleaning without requiring tools. The chambers are tubes having their ends removably plugged, and one of the plugs in the boiling chamber carries the heater with it, the heater coils supporting a convection sleeve which is easily separated therefrom for cleaning. The water level in the boiling chamber is controlled by connection with a separate tank having a float valve setting its own level, and the unit has automatic electrical shut-off switches operative when the sump is full or in case of overheating.
