Merck Milli-Q Water Purification Systems

The Milli-Q^® Lab Water Solutions portfolio of benchtop water systems includes both pure and ultrapure systems to meet any lab’s needs. From sensitive QC analyses to buffer preparation and glassware rinsing, this collection of compact systems has your lab covered.

Type 1 ultrapure water is ion-free (resistivity 18.2 MΩ·cm) with low total organic carbon (TOC) content. Ultrapure water is recommended for sensitive laboratory applications such as advanced analytical techniques (e.g. HPLC, UHPLC, LC-MS, ICP-MS, GF-AAS), molecular biology applications (e.g. PCR, sequencing), and to prepare buffers and culture media for mammalian cell culture.

Type 2 pure water is recommended for general lab use, such as to prepare buffers, reagents, and culture media, and as feed for other equipment (e.g. Type 1 systems, clinical analyzers, dishwashers, stability test chambers, etc.). Our Type 2 systems incorporate environmentally friendly Elix^® electrodeionization (EDI) technology which produces constant-quality pure water while eliminating the need for hazardous chemical regeneration procedures, costly resins, changing DI cartridges, and adding softeners.
