LAB Water Purification Systems

Typically, Type I ultrapure water has a resistivity of 18.2 MΩ·cm and TOC levels below 10 ppb, making it suitable for highly sensitive applications such as ICP-MS, HPLC, LC-MS, and molecular biology.

Type II pure water still maintains high levels of purity. It is suitable for general lab use, such as feeding clinical analyzers, buffer preparation and rinsing.

Defined by the Clinical & Laboratory Standards Institute (CLSI), CLRW is the minimum grade of pure water that should be used in clinical laboratory applications. 

RO water has the lowest level of purity among pure water types. It is recommended for basic lab applications, such as glassware cleaning, heating baths and feed water for Type I water systems.
