Distilled Water


water that has been freed of dissolved mineral salts, organic matter, ammonia, carbon dioxide, and other impurities by distillation. Distilled water is used as a solvent in chemistry and physics laboratories and in medical practice. Its quality is controlled by checking its electrical conductivity (not over 10-6 mho [ohm-1]) and dry residue (not more than 0.1 mg per 1 / of evaporated distilled water). In some cases, for example, when using distilled water for subcutaneous infusions, it is also sterilized. Distilled water is stored in closed tin vessels or in carboys of chemically resistant glass.
