Sartorius - Type 2 Lab Water Systems - Arium Advance EDI

Type 2 Ultrapure Water Systems

The arium advance EDI provides Type 2 water in consistently high quality. The innovative iJust makes the best use of environmental resources by automatically optimizing water usage. Unlike conventional water purification systems, the unique touch-function display in combination with the intuitive menu navigation ensures easy operation. With a flow rate of 5 or 10 l/h, automatic RO membrane backflushing, the latest EDI technology and a constant flow rate, the arium® advance EDI is the best choice for both routine and demanding applications.

In addition to pretreatment and purification by reverse osmosis modules, softening and electrochemical deionization is also carried out in the third purification step. By means of this modern EDI technology, the arium® advance EDI safely and reliably guarantees the removal of all impurities contained in the feed water.

Innovative Bag Technology
The pure water is stored in the enclosed arium® Bagtank system. This guarantees
optimal storage of the pure water and protects against secondary contamination.
Time-consuming tank cleaning intervals are eliminated thanks to the interchangeable bag.


iJust features an innovative technology that optimizes water production. The intelligent arium® software controls a valve on the concentrate outlet based on the data measured for CaCO3 and CO2. iJust therefore optimizes product water quality and water usage.


– Microbiological media and reagents
– Solutions for chemical analysis and synthesis
