The Simplicity system produces ultrapure water on demand from pretreated water (Elix system distilled, deionized or reverse osmosis water). Designed for scientists who require less than five liters of ultrapure water per day, the system is suitable for the production of mobile phases for chromatographic separations, preparation of blanks and standard solutions for spectrophotometry, spectroscopy or other analytical techniques, as well as buffer preparation for biochemical experiments. Type I water (18.2 MΩcm at 25 C ultrapure water) provides an economical alternative for laboratories currently using bottled water. As water is produced and used at the point-of-use, water quality is not subject to contamination. For applications such as HPLC, GC and TOC analysis, a built-in dual-wavelength UV lamp (185 and 254 nm) reduces organic contaminants to <5 ppb. In addition, a range of final polishers is available to provide bacteria-free, pyrogen-free or nuclease-free water, depending on requirements. Millipore Corp.800-MILLIPOREwww.millipore.com/bioscience
