The arium® comfort I is a combined system for producing ASTM Type 1 ultrapure water and Type 3 pure water. This system features the latest reverse osmosis technology and a unique filter cartridge to deliver water of the highest reproducible quality.

The arium® comfort I consistently delivers reagent-grade ultrapure water at rates of up to 2 l/min. The quality of this water even exceeds ASTM Type 1 specifications. Moreover, arium® comfort I supplies Type 3 pure water at rates of 8 or 16 l/h.

Pure water produced by arium® comfort I is stored in the unique, closed arium® bagtank system, which reliably protects your purified water from secondary contamination. This ensures that you consistently obtain the best water quality and, therefore, reproducible results.

Lowest TOC content

The 185 | 254 nm UV lamp, which can be integrated as an option, not only prevents microbiological growth, but also minimizes total organic compounds (TOC) in purified water. The low TOC level of < 2 ppb in arium® water therefore ensures the reproducibility and reliability of your lab results. Moreover, you can have TOC readings continuously checked and displayed in real time by our optionally integrated TOC monitor specially developed for this ultrapure water system.
