The world’s first laboratory water purification system
with re-usable cartridges.

Avidity Science® has developed the Solo™ S - A revolutionary new sustainable water purification system that means you no longer need to send large volumes of plastic waste to landfill. Laboratory Ultrapure water directly from tap water, producing up to 10 liters per day of Type 1 water from a single unit.  

Type 1 / Ultrapure Water Applications

Type I water from the Solo™ S 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 I water is required for critical laboratory applications such as:

  • Analytical instrumentations: HPLC, UPLC, AA, ICP, LC-MS, GC-MS, ICP-MS, Ion Chromatography, Electrochemistry, Particle Counter, TOC Analysis
  • Life science instrumentations: PCR, DNA sequencing, electrophoresis
  • Preparations for cell culture, molecular biology and monoclonal antibody applications


Unrivalled Sustainability

  • Unique cartridge design enables reuse, eliminates plastic cartridge waste disposal and delivers up to 90% reduction in carbon emissions
  • Cartridge housing made from 100% recyclable material
  • Treatment media can be recycled with an AvRecycle™ plan

The AvRecycle™ Plan

  • Revolutionary consumable cartridge design with no glue or welding allows for complete separation of the internal media from the outer housing
  • Annual consumables can be returned to Avidity Science for reprocessing – not thrown away
  • Recycling consumables is a comprehensive process of disassembly, emptying and cleaning the plastic cartridges before refilling and testing
  • Innovative, non-carbon pre-treatment media for reverse osmosis membrane protection can be backwashed and reused
  • All returned cartridges will be reused and, in return,  you will receive a rebate on your next Annual Consumable pack purchase!

Green Credentials by Design

  • Mercury-free bacteria control LED UV technology, eliminates the downstream challenge of dealing with mercury waste
  • Solo™ S is delivered in plastic-free packaging, certified to FSC, designed for sustainability
  • Revolutionary pump design and reverse osmosis membrane flow path, to maintain water quality with reduced energy and water consumption
  • Automatic switching to energy saving mode after a period of inactivity, further reducing energy consumption
  • Solo™ S is delivered in plastic-free packaging, designed for sustainability

Smart Dispensing With Full Flexibility

  • Ultrapure water delivered at up to 1.2 liters/minute minimizes research delay
  • Volumetric dispensing from 100ml to 4 liters allows you to work while water is delivered
  • Configurable dispense button to provide full control when using manual and volumetric configuration
  • Configurable flow rate down to drop-by-drop dispensing assists precision filling in a single vessel

Ingenious Data Tracking and Reporting

  • Near Field Communication (NFC) enables consumable identification and secure data logging ensuring traceability
  • Paperless data management with SD card technology
  • Data acquisition meeting regulatory compliance

Intuitive Touch Screen Display


  • 5-inch, TFT color screen with simple icon navigation
  • Real time monitoring in multiple languages
    • Dispense speed
    • Dispense history
    • Cartridge health
  • Password protection for critical operating parameters

Effortless Operation and Maintenance

  • System alerts when cartridges require changing –  access is easy
  • System status notification providing visual indication of the water purification status via a color-coded dispense button
  • Built in leak detection provides system security
  • Semi-automatic sanitization process is simple and safe
