Duo-i 1+3 Water Purifier

Avidity Science - Duo-i 1+3 Water Purifier

Duo-i 1+3 - Efficient Dual Quality Reverse Osmosis and Ultrapure Water

The DUOtm-i III.I Laboratory Water Purification System produces up to 30 L/hr of Type III water directly from tap-water. It dispenses up to 2 L/min of the both Type III pure water and Type I ultrapure water from a flexible dispenser.

Manufactured to ISO 9001:2015 standard. Certified to IEC 61010-1:2010 and EN 61326-21:2013

PRODUCT FEATURES

  • Dispense Type 1 and Type 3 (optional) from the remote dispensers.
  • Unique twin pass RO technology (< 10 μS/cm, typical < 5 μS/cm if feed condition is < 2000 μS/cm).
  • Data capture with printable option.
  • Dispense Type 3 water from reservoir.
  • Adjustable dispenser.
  • Cartridge traceability with data tag.
  • Auto Reservoir sanitation option.
  • Interactive 7" touch screen.
  • Colour coded dispensing stations with up to three flexible dispensing options.

APPLICATION SCOPE

Reverse Osmotic Type III Water Applications

Type III Water is required for sensitive laboratory applications:

  • Autoclave feed
  • Glasswasher feed
  • Feed to Ultrapure Water Systems
  • Hydroponics
  • Steam Generators

Ultrapure Type I Water Applications

Type I Water from the Duotm-i system meets or exceeds Type I water standards as specified by ASTM, CAP, ISO 3696, CLSI, JIS K0557, and high-purity water as described in USP, EP, and ChP. Type 1 water is required for critical laboratory applications such as:

  • Molecular Biology, Immunology, & Pharmacology
  • Electrochemistry
  • Critical Cell and Tissue Culture
  • GF AAS, HPLC, IC, ICP-MS, GC, MS
  • DNA Sequencing
  • Genomics and Proteomics
