ABSTRACT:
Apparatus and method for producing and maintaining high purity water of a quality suitable for delicate laboratory analysis work. The apparatus is comprised of a cylindrical stainless steel two gallon container for holding a batch of distilled water, a removable cover forming a closure on the container and carrying close to the wall of the container a closed bottom transparent quartz tube extending substantially to the bottom of the container and housing therein an elongated mercury vapor lamp substantially the height of and parallel to the wall of the container and electrically coupled to a starter, ballast and On-Off switch circuits in a housing fixed to the top of the cover and adapted for coupling to an alternating current power source for thereby causing the mercury vapor lamp to become a source of photochemically active 185 nanometer wavelength range electromagnetic radiation in the batch of water in the container and causing a gentle steady state convection circulation of the water about the source of the electromagnetic radiation which results in the photochemical oxidation of any organic matter in the water and maintains the water in a state of high purity.
