Duo™ II.I Two-In-One Water Purification System – Deionised & Ultrapure Water

The Avidity Science  Duo™ II.I water purification system provides two water qualities within one easy to use system – Types 1 (Ultrapure) & 2 (Deionised). Total Organic Carbon (TOC) monitoring is critical where organics affect results, so a real time TOC reading will provide absolute confidence in your water quality.

The Duo™ II.I combines the trusted purifying technology of the Geno™ II Type 2 system, with the Alto™ I Type 1. Process potable water to Type 2 for the storage reservoir; to be used for general laboratory applications, or for when you call for Type 1 from the dispenser as required.

With the same patented anti-vibration technology as the Geno II T, Puro III T the Duo™ II.I has a quiet operation volume, as to not disturb your working environment.


Type 2 / Deionised (DI) Water

The system is fed from mains water and produces Type 2 DI water up to 160 litres per day into a reservoir size of your choice. The Duo II.I has a reverse osmosis flow rate of up to 25 litres per hour. Type 2 water is used for:

  • Buffer and Media Preparation
  • Sample Dilution & Reagent Preparation
  • Spectrophotometry
  • Protein Electrophoresis
  • Cytology & Histology
  • Glassware Washing & Rinsing
Type 1 / Ultrapure Water

The Duo™ II.I also produces Type 1 Ultrapure water at 18.2MΩ·cm swiftly on demand from the integrated dispenser or optional remote dispenser at up to 2 litres per minute. The output can either be continuous or volumetrically dispensed with an intuitive and simple software control. Type 1 water is used for:

  • Molecular Biology
  • Electrochemistry
  • Critical Cell and Tissue Culture
  • DNA Sequencing
  • Genomics
  • Proteomics
  • Immunology
  • Pharmacology

Dispense Options

  • Ultrapure water directly from the unit
  • Ultrapure water from a remote dispenser
