ABSTRACT:
An apparatus for the continuous production of high-purity water includes a distillation flask, a carboy and a condenser unit, all of borosilicate glass. A respective filter is provided between the ambient atmosphere and the interiors of the flask, the carboy and the condenser unit to remove airborne bacteria and dust particles. An inlet valve is provided for feeding water to be purified into the flask, all water-contacting parts of this valve being of polytetrafluoroethylene. The open parts are interconnected with flexible, polytetrafluoroethylene tubing. A two-way, stopcock allows high-purity water to be removed from the carboy.
