Water is the most common reagent used in the laboratory, and while water quality can often be overlooked, the grade of water being used in an application is critical.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The number of bacterial cells with the potential to multiple and grow in the water is counted and reported as colony forming units CFUs per unit volume ml. Minute traces of salts or biological contaminants can result in unfortunate consequences when culturing cells or performing analytical measurements of biological macromolecules.
