Milli-Q® Water
for Your Science
Focus on creating breakthroughs
Water is arguably the most essential reagent in any laboratory. Its purity—and the consistency of that purity—are crucial for obtaining accurate and reproducible experimental results. This is particularly important for highly sensitive analytical techniques such as LC-MS and ICP-MS, as well as genomic techniques like next-generation sequencing (NGS) and CRISPR.

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.
