Uhq Water Purification Systems

Not yet rated

Type I water for laboratory applications

  • Disposable deionization, adsorption and filtration cartridges are easily replaceable
  • UV reactor cell reduces micro-organisms and TOC levels
  • Specially controlled regenerated ion exchange resins assure absolute ionic purity
  • Quality meter continually displays resistivity in MΩ -cm for monitoring water quality
  • Easy to use

USFilter UHQ™ System produce 18 MΩ -cm quality water in a compact, economical and low-volume unit. Providing flow rates up to 0.75 lpm, these systems deliver Type I water for a wide range of demanding lab applications. Ideal for atomic absorption spectrophotometry, ion chromatography and ICP-MS. Water conforms to BS 3978 (1987) grade I water for lab use, ASTM Type 1, CAP Type 1, NCCLS Type 1 and ICMC 'IDEAL' specifications.

UHQ II incorporates a reverse osmosis (RO) membrane to provide 18 megohm water from a tap water feed. The effcient, low-pressure thin-film RO membrane deionizes the feedwater and removes colloidal and microbiological impurities. The UHQ PS system, which does not include RO, is designed to produce 18 megohm water from pre-purified tap water. All UHQ units come equipped with cartridges and UV lamp. UHQ II comes with an RO membrane.
