Laboratory Ultrapure Water System (Crystal E series)
The Crystal E ultrapure systems are economy class, multi-purpose, water purification systems.
All Crystal E systems produce two types of water: Ultrapure (ISO 3696 Grade 1) and
Pure (ISO 3696 Grade 2). Ultrapure water produced by the Crystal E systems has resistivity 18.2 MegaOhm*cm (conductivity 0.055 μS/cm). This exceeds requirements of all the relevant standards (ISO 3696 Grade 1, ASTM Type I, CLSI Type I). Purified water is collected in a storage tank. The recirculation system ensures a consistent quality of water, and a low level of organic carbon content (TOC). TOC is <2 ppb for "HPLC" and "Bio" configurations, and 5-10 ppb for the "Trace" configuration The dispensing rate of high-quality Ultrapure water is 2 L/min. Pure water produced by Crystal E systems can be used for labware e washing,wet chemistry methods, flame spectrophotometers,et c. P.ure water is dispensed directly from the storage tank.Th e dispensing flow rate of Pure water is 4 L/min.
Crystal E ultrapure water systems are available in the following configurations:
• Crystal E Trace System (P/N CE-1001) produces water for inorganic trace analysis. This water is recommended for atomicabsorption spectrometry (withgraphite furnace atomizer), ICPOES analysis, ICPMS and other inorganic analytical methods.
• Crystal E HPLC System (P/N CE-1101) produces water with very low organic carbon content (TOC) to comply with the requirements of liquid chromatography methods. Crystal E HPLC water can also be used for some microbiological and molecularbiology applications.
• Crystal E Bio System (P/N CE-1201) produces water with very low organic and RNase/DNase content, intended for molecular biology,including Nase- sensitive applications.
