Sartorius - Type 3 Lab Water Systems - Arium Advance Reverse Osmosis

Type 3 Ultrapure Water Systems

The arium® advance RO provides Type 3 reverse osmosis water of the highest quality. 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 provides an easy-to-use system.

With a selection of constant flow rates of up to 8 l/h, 16 l/h or 24 l/h and automatic RO membrane backflushing, the arium® advance RO is the optimal choice for daily laboratory applications.

Each Type 3 system continuously monitors the water quality: One glance at the display will keep you updated about all important data. That’s why arium® advance RO systems are ideal for routine lab applications, such as supplying feed water to lab instruments like pure water systems, autoclaves, glassware washers, humidifiers and water baths, and for preparation of non-critical buffers and solutions.

The system attains the highest ion retention rates, while ensuring optimal pure water yield. It reliably removes oxidants, heavy metal ions and particulates from feed water. The pure water produced is stored in the arium® Bagtank system and, if a Sartopore® 2 150 final filter is used in this system, is nearly free of microorganisms.

For larger production volume, between 50 and 300 l/h, Sartorius offer the 613L series. Due to the high volumes this device is ideal to feed laboratory equipments.

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.


– 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
