Reverse Osmosis System arium® advance RO
Sartorius Stedim Biotech

The arium® advance RO provides type 3 reverse osmosis water of the highest quality. The innovative iJust makes the best use of environmental resources by automatically optimising water consumption. Unlike conventional water purification systems, the unique display with touch functions in combination with the intuitive menu navigation creates an easy to use system. With a flow rate of up to 16 l / h, the automatic RO membrane backflush and a constant flow rate, the arium® advance RO is the optimal choice for daily laboratory applications.
  • Display with touch function: simple navigation, clear menu, operation by lightly touching the display - even with gloves.
  • High system flexibility: space-saving installation as bench-top, wall mounted or built-in unit.

iJust is based on an innovative technology which optimises the water production. The intelligent arium® software controls a valve at the concentrate outlet acc. to measurement data for CaCO3 and CO2. iJust thereby optimises product water quality and water consumption.
  • Premium product water quality at all times.
  • Optimised, economic water consumption.
  • Guaranteed longer life of down-stream ultrapure water systems.

Feed water for ultrapure water systems, rinsing of glass and laboratory containers, feed water for various laboratory devices, such as humidifiers, autoclaves and lab glassware washers.
