Avidity Science

Deionization -Ion exchange

This process removes ions from water, usually RO water, with the use of synthetic resins. The ions are removed from the water through a series of chemical reactions. These reactions occur as the water passes through the ion exchange resin beads. Gradually, all unwanted ions are replaced by hydrogen and hydroxyl ions which combine to form pure water measuring at 1-15meg ohm. 

Our high-quality water systems are manufactured in the US to the most demanding Standards. Avidity holds all spare parts and consumables for local delivery.  Our local teams of expert water engineers can carry out your routine servicing and maintenance.  Complete turnkey packages for installation, commissioning and on-going service are available here.

Type 2 water is used for:

• General laboratory applications requiring higher ionic purity
• Buffer make up
• Media production
• Sample dilution and reagent preparation
• General Chemistry
