Key Features:
  • Maximum flowrate (at 10psi pressurized feed): 0.53 gal./min. (2L/min.)
  • Inlet water temperature: 4° to 40°C (40° to 104°F)
  • Built-in UV oxidation chamber in some models oxidizes and measures the levels of organics in the water
  • 0.2μm absolute final filter maintains bacterial- and particle-free water
  • Systems can be customized with a cartridge pack (available separately) to meet specific feedwater needs

System Operation Features:

  • Volumetric or timed dispensing of ultrapure water
  • Multilanguage display
  • Whisper-quiet operation
  • Pressure-regulating valve that minimizes problems associated with fluctuations in feedwater pressure
  • Automatic sanitization cycle that keeps system clean
  • Standby mode that recirculates water every 10 minutes during periods of nonuse to maintain water quality
  • Automatic calibration verifies electronics and assures accurate purity readings
  • Can be wall- or bench-mounted without additional items
  • Optional Thermo Scientific Barnstead Remote Dispenser and Thermo Scientific Barnstead Accudispense Volumetric Dispenser available for water delivery up to 8′ away

Nanopure Analytical:

  • For sensitive analytical procedures including atomic absorption, ICP and ICP/MS, ion chromatography (IC), gas chromatography (GC) and high-wavelength HPLC

Nanopure Analytical UV:

  • For critical applications requiring 18.2MΩ-cm water with 1 to 5ppb TOC, including low-wavelength HPLC, IC, GC/MS and TOC determinations
  • Uses a dual-wavelength UV lamp to oxidize organics down to virtually undetectable levels and maintain minimal bacterial levels within the system
  • Automatically alerts user for UV lamp replacement

Nanopure Biological UF:

  • For any pyrogen determinant analysis including PCR and cell and tissue culture
  • An ultrafilter in the system produces ultrapure water with undetectable levels of pyrogens, less than 0.001EU/mL, log reduction values (LRV) over 6
  • Prevents buildup of contaminants on membrane surface; Nanopure periodically flushes water to drain
  • Automatic cleaning cycle enables routine cleaning with the push of a button

Nanopure Life Science UV/UF:

  • For the most demanding molecular biology applications including PCR, electrophoresis, cell and tissue culture
  • Includes latest advances in ion exchange and filtration technologies, as well as dual-wavelength UV bulb and ultrafilter
  • Is of the the only validated water systems with the ability to remove nucleases such as RNase and DNase, as well as DNA, from challenged feedwater
  • Includes automatic cleaning and automatic and manual ultrafilter flushing
  • Produces 0.53 gal./min. (2L/min.) ultrapure water containing <0.001 EU/mL of pyrogens, 0.01 CFU/mL bacteria, <0.003ng/mL RNase, <0.4pg/μL DNase, TOC values 1-5ppb and resistivities up to 18.2MΩ-cm

All Models Available with TOC-Monitoring Option:

  • TOC models measure and display Total Organic Carbon content from 1 to 250ppb.

Ordering Information:
