Thermo Scientific™ Amberlite® IRN-78, Ion exchange resin cationic type (OH-) ion-exchange resin

Thermo Scientific™ Amberlite® IRN-78 is a high-capacity, strong base anion (SBA) exchange resin in hydroxide (OH⁻) form, specifically designed for nuclear-grade and ultra-pure water treatment applications. This high-purity, polystyrene-divinylbenzene gel-type resin provides excellent ion exchange capacity, rapid kinetics, and superior chemical stability, making it ideal for nuclear power plants, semiconductor manufacturing, and high-purity deionization systems.

Amberlite® IRN-78 is a nuclear-grade, highly cross-linked ion-exchange resin that efficiently removes anionic contaminants such as sulfates (SO₄²⁻), chlorides (Cl⁻), nitrates (NO₃⁻), bicarbonates (HCO₃⁻), and silica (SiO₂). Its low organic leachables and high resistance to degradation make it a top choice for critical water purification applications where ultra-low conductivity and minimal ionic contamination are required.
