Tristel Rinse Assure (RA)

Tristel RA is a water purification system that combines Tristel ClO₂ with reverse osmosis and filtration.

It ensures both bacteria-free rinse water and filter disinfection. Tristel RA eliminates bacteria, prevents biofilm formation, and significantly lowers endotoxin levels, ensuring bacteria-free rinse water while requiring less electricity than RO alone.

You can read more about Tristel RA in industry publications too, see our news and events page for more information.

Chemistry

Tristel RA utilises Tristel’s proprietary chlorine dioxide chemistry which is widely regarded as one of the most effective disinfectants for biofilm removal and prevention.

Tristel RA doses low levels of Tristel’s proprietary chlorine dioxide chemistry into the incoming water supply used during an EWD’s decontamination cycle. This powerful biocide is generated by mixing Tristel Base Solution (citric acid) and Tristel Activator Solution (sodium chlorite) at point of use.

Chlorine dioxide does not form hazardous by-products or halogenated compounds.

Due to the way chlorine dioxide breaks down and destroys microorganisms, resistance cannot develop over time. Find out more about the mode of action of chlorine dioxide here.

Efficacy

Biofilm that builds up in plumbing systems can cause pipes to become narrow and eventually break off. Biofilm can then end up in the water used in Reverse Osmosis or filtration, leading to re-contamination of endoscopes and the EWD.

Chlorine dioxide is proven effective against fast and slow growing bacteria that are often found in water systems.

Compatibility

Chlorine dioxide as dosed by Tristel RA does not cause damage to endoscopes due to the low concentration used.

The low doses of chlorine dioxide are highly compatible with other chemistries, so do not affect the chemical composition and efficacy of detergents and disinfectants commonly used in EWDs.
