It is important to choose the correct quality of water for your applications. While too low quality may affect your experiments or analyses, too high quality may be unnecessarily expensive. Applications such as media and buffer preparation, AAS and photometry analysis, which are less critical or sensitive, are suitable for pure water. Pure water can also be used for general laboratory tasks such as rinsing, or as feed water for water-consuming systems (e.g. washing machines, autoclaves or Type 1 water purification systems).
