The still is made of a sturdy borosilicate glass that allows perfect viewing of the distillation process. Glass is exposed so the still requires a good location to avoid accidental breakage. A built-in thermostat protects the still from overheating if the water supply should fail. It is mounted on a metal stand that sits on a table or can mount on a wall. Cleaning is easily done by adding the cleaning agent to a built-in funnel and drainer through a stopcock. 50/60 Hz, UL listed. Dimensions are 20" x 6" x 18".
