by Thermo Scientific

Barnstead MicroPure Water Purification System by Thermo Scientific
Flexible with mix and match systems and an optional water feed tank
Compact Barnstead MicroPure systems are ideal for producing Type 1 Ultrapure water for a variety of applications in molecular biology, microbiology and analytical chemistry laboratories.
  • Produces 15 liters a day of Type 1 ultrapure water
  • Variable speed dispensing units with mix and match system options in UV, UF, UV/UF or with optional storage tank (ST) to achieve specific water purity
  • Monitors feed water quality for consistent production of ultrapure water and to extend and maximize cartridge life
  • Recirculation pump prevents bacterial growth of stagnant water, monitors all system functions and signals immediate display of fault messages
  • Validated 0.2 µm final filter with folded membrane can be sterilized up to 5 times
  • Excellent filters automatically flush ultrafilter for highest retention of nucleases and endotoxins
  • System equipped with pressure reducer, ultrapure cartridge, and 0.2 µm sterile filter
  • Backlit display tilts for convenient viewing
  • One-year manufacturer warranty for parts and labor

  • Ultraviolet (UV) Photo Oxidation: Eliminates trace organics and inactivates microorganisms and their metabolites in feed water; prevents bacterial contamination; oxidizes organics to produce pure water with low TOC (Total Organic Carbon) levels
  • Ultrafiltration (UF): Removes molecules (pyrogens, nucleases, microorganisms, particulates) above their rated size; critical for tissue culture, cell culture and media preparation
  • UV/UF: Produces water that is virtually free of all impurities; removes nucleases and DNA; produces water with low TOC (Total Organic Carbon) and pyrogen levels; produces reagent grade water with resistivity up to 18.2MΩ.cm and no detectable RNase, DNase or DNA
  • Storage Tank (ST): 6 liter feed water reservoir for pretreated water storage for system placement without direct access to a water line; available with UF, UV and UV/UF



  • Molecular Biology and Microbiology: Cell and tissue culture; PCR, DNA sequencing; Electrophoresis
  • Analytical Chemistry: HPLC; GC, GC-MS, ICP-MS, AA; TOC Measurements, IC
  • Instrumental analysis, sample preparation and glassware rinsing
