The Sartorius technology group has extended its successful arium lab water family by three new product lines: the arium pro ultrapure water system, the arium advance pure water system, and the arium comfort combination system. These new product lines generate Type 1 to Type 3 ultrapure and pure water; the arium comfort series is a space-saving combination unit that produces Type 1, Type 2 and Type 3 water. An integrated UV lamp prevents microbiological growth, thus reducing the TOC content to a minimum. If a Sartopore 2 sterilizing-grade filter is used, ultrapure water is practically free of microorganisms when dispensed, accordint to the manufacturer. Pure water is stored in the new arium bagtank system, which consists of a closed housing with an integrated single-use bag to ensure consistently high water quality over a relatively long storage period and thus reproducible results. The arium iJust software optimizes the quality and usage of pure water, extending the life of the downstream ultrapure water systems. Benchtop, wall-mounted or built-in units are available.
