Thermo Scientific Ion Exchange
and Regeneration

High quality demineralized water

Economical solutions for your applications

Thermo Scientific
Ion Exchange Cartridges

Ion exchange cartridges are an economical solution for
converting tap water to demineralized, deionized water.
Whether you need a few liters per week or large volumes
daily, we have the most suitable, economical, reliable
solution for your application.

• Feed water for dishwashers, autoclaves,

climatic chambers and humidifiers

• Filling water baths and cooling circuits

• Rinsing components

• Battery water

• Emergency supply water

• Medical applications

How does ion exchange work?

The process removes ions from tap water with the use of synthetic resins. These resins are
chemically altered to have an affinity for dissolved inorganic ions and are divided into two
classifications: cation removal resins and anion removal resins. Cations have a positive charge
and include sodium (Na+), calcium (Ca+2) and magnesium (Mg+2). Anions have a negative charge
and include chloride (Cl-), sulfates (SO
the water through a series of chemical reactions. These reactions take place as the water
passes through the ion exchange resin beds. Cation resin contains hydrogen (H+) ions on the
surface, which are exchanged for positively charged ions. Anion resin contains hydroxide (OH-)
ions on its exchange sites, which are exchanged for negatively charged ions. The final product
of these two exchanges is H+ and OH-, which combine to form water (H2O).
