General description

The Milli-Q® IX 7003 system is a compact, ergonomic, mercury-free and intelligent water purification solution that delivers consistently high quality pure water on demand. The system features three separate and distinct components:
  • The pure water production unit offers flexible installation and simplified maintenance.
  • The intelligent pure water storage tank allows maximum protection from any external source of contamination.
  • The redesigned E-POD® point-of-delivery unit provides convenient, rapid access to pressurized pure water. A large touch screen allows for intuitive interaction and displays essential data for complete user reassurance. Up to two E-POD® dispensers can be used with each IX production unit at different locations within the same laboratory, or in adjacent laboratories.
(Storage tank and point of delivery to be ordered separately)

The Milli-Q® IX 7003 Water Purification System produces pure (Type 2) water.
  • For critical lab applications such as: microbiology culture media preparation, staining solutions for histology and cytology, immunohistochemistry (IHC), electrophoresis gel and buffers, western blotting, immunoassays (ELISA, RIA), drug dissolution testing, biological oxygen demand (BOD), chemical oxygen demand (COD), UV/Vis spectroscopy, titration, etc. It can also be used to prepare samples for laser fluorometry, in the synthesis and characterization of membranes for fuel cells, or in the synthesis of nanocomposites by electrochemistry.
  • For general lab applications: Sample preparation (dilution, extraction...), buffer and reagent preparation, glassware rinsing, etc.
  • To feed laboratory instruments like autoclaves, dishwashers, weathering and stability test chambers, clinical analyzers and slide stainers, hydrogen generators, and ultrapure water systems (e.g. Milli-Q® IQ 7000 system).

Features and Benefits

  • Delivers pure water quality that meets Pharmacopeia and ISO requirements.
  • Easy to use with carefree maintenance.
  • Delivers reliable Type 2 pure water with continuous quality monitoring.
  • Compact with space-saving installation options.
  • Mercury-free ech2o® lamps use UVC-LED technology to inactivate bacteria.
  • Uses IPAK Gard® pre-treatment cartridge protects the reverse osmosis (RO) membrane to improve system performance.
  • Elix® electrodeionization (EDI) module delivers consistently superior quality pure water with no maintenance and at low running costs.
  • Intelligent pure water storage solution provides multi-targeted protection from bacterial, particulate, and CO2 contamination by using bactericidal UV lamp, a vent filter, automatic sanitization module (ASM), and an overflow sensor.
  • Automatic e-record archiving.
  • Integrated, simplified data management.
