To produce ultra pure water Astacus² systems are fed with de-ionized water.

Astacus² models are designed for a daily consumption of less than 100 l and are equipped with a MemPak purification cartridge.

Astacus² is available in different versions (Reagent, Analytical & LifeScience) to meet the specific requirements of ultra pure water for different applications.

The systems also have the new fixed and flexible dispenser and a big touchscreen with easy to use menus and wizards.
