Pico™ - Reverse Osmosis or Deionised Water

The Pico™ is the latest addition to the Avidity Science range of high quality water systems which are manufactured in the UK to ISO9001:2015 certification. The Pico™ is a complete, “all in one” water purification system which provides general laboratory water with many unique features. It has low energy consumption, minimal water wastage and maximises the use of your laboratory space. It is the most environmentally friendly product on the market.


The Pico™ utilises proven water purification technologies to provide Type 2 (Deionised Water) or Type 3 (Reverse Osmosis) water, on request.

Type 2 / Deionised Water

  • Buffer and Media Production
  • Sample Dilution and Reagent Preparation
  • Spectrophotometry
  • Protein Electrophoresis
  • Cytology & Histology
  • Glassware Washing & Rinsing

Type 3 / Reverse Osmosis Water

  • Glasswasher Feed
  • Autoclave Feed
  • Feeding Ultrapure Water Systems
  • Hydroponics
  • Steam Generators

Handing You The Control

The intuitive touch-screen control panel gives you instant access to the data you need. Check-up on water quality and how many litres are available in the tank, without taking your gloves off.

Maintaining Quality at a Lower Cost

The economic benefits of the Pico™ range continue throughout the life of the product. Replacement of the modules has been designed with ease in mind, meaning that the user can carry out basic and essential maintenance tasks themselves.

The unique reverse osmosis (RO) cartridge has an in-built pre-treatment which only requires changing once per year (dependent on usage). This maintains optimum performance as there is no deterioration of quality from an over-worked RO membrane. The high recovery rate means the cost of waste water is also kept to a minimum.

It is recommended that a full mechanical service is completed by an Avidity Science trained Service Partner on an annual basis to maintain the integrity of components.

Additional Information

All models in the range are supplied with the first set of consumables, meaning they are ready to plug-and-go.
