Selecting the Right Water Quality for Your Applications
Water is probably the most used reagent in every laboratory. This makes its purity—and consistency of purity—critical to obtaining accurate and reproducible experimental results. This is especially true for analytical techniques (e.g., LC-MS, ICP-MS) and genomic techniques [e.g., next-generation sequencing (NGS) and CRISPR] that are becoming increasingly sensitive.

Water for Environmental Testing
Sensitive analytical techniques are used to detect trace contaminants in our environment and drinking water. These techniques, such as ion chromatography (IC), LC-MS and ICP-MS require reagent water to be free of the analytes being measured. Read here about ensuring optimal water quality that is critical for results reliability and accuracy in environmental testing.

What Water Quality does your Lab Require?
Norms define different laboratory water grades for both technical and economic reasons. These norms help ensure that the correct water type is used for a specific application while limiting laboratory operating costs. For example, Type 1 ultrapure water is more expensive to produce than Type 2 pure or Type 3 reverse osmosis (RO) water.
- Type 1 ultrapure water is required for critical laboratory applications such as HPLC mobile phase preparation, blanks and sample dilution in HPLC, GC, AAS, ICP-MS and other advanced analytical techniques; preparation of culture media for mammalian cell culture; production of buffers and reagents for molecular biology applications (DNA sequencing, PCR); and preparation of solutions for electrophoresis and blotting.
- Type 2 pure water is used in general laboratory applications such as buffers, pH solutions, histology reagents and staining solutions, microbiological culture media preparation; as feed to Type 1 water systems, clinical analyzers, stainless steel autoclaves, lab washers, hydrogen generators or weathering test chambers.
- Type 3 RO water is the lowest laboratory water grade, recommended for glassware rinsing, heating baths and filling autoclaves, or feeding Type 1 ultrapure lab water systems.
