Ultrapure Water straight from the tap

The Astacus2 ultrapure water system produces ultrapure water using a combination of optimized mixed-bed cartridges. The produced pure water can be tapped with a flexible dispenser. To ensure consistently high ultrapure water quality, the water is automatically circulated when no ultrapure water is being drawn from the system.

Configurations, operation

The Astacus2 ultrapure water system is available in different configurations for different ultrapure water quality requirements - tailored to the respective applications (reagents, Analytics and Life Science). The device has a color touchscreen for operation and the clear display of recorded data and warning messages .

Automatic conductivity monitoring

The µS control ensures that the feed water is always at least of drinking water quality and thus protects the cartridges from unsuitable feed water.

Diagnostics and Maintenance

Thanks to the integrated self-diagnosis module, service times and costs reduced. With the help of the maintenance tool integrated into the software, the device can be maintained by the customer himself.


The specially designed housing contains all components. Maintenance work can be easily carried out after removing the side panel. This service access provides easy access to the ultra clean module, UV lamp and ultrafiltration module strong>.

Integrated conductivity monitoring through µS control

The µS control switches off the water supply if the feed water has too high conductivity, to protect the cartridges from unsuitable feed water. The feed water must be of at least drinking water quality.

Integrated TOC monitor (TI version)

TOC monitoring for continuous checking of the water for organic components during operation and when not in use

Volumetric controlled water release

The dispenser enables volumetrically controlled water dispensing in 0.1 liter increments with a dispensing volume of 0.1 to 99 L. With the help of the overflow protection, the water can be dispensed without supervision.

Easy operation and support by software tools

Control and display of data and warnings via color touch screenself-diagnostic module and Maintenance tool easy to operate via touchscreen

Space-saving thanks to wall mounting

If you order the wall-mounted configuration, you mount the entire system to the wall, saving valuable desk space.
