    There are a number of analytical lab procedures which rely on ultra pure water. Contaminants of any kind cannot appear to be present when labs use water as part of an analytical process. Therefore water is graded based on the level of impurities it contains. There are sophisticated purification devices used to turn potable water into a medical or lab grade water designed for analyses.
