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 a 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 customers’ 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 colour 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
  • Semiautomatic sanitization process is simple and safe
