OptiPrep² Water Treatment

Ultrapure Water straight from the tap

The OptiPrep2 ultrapure water system produces ultrapure water using a combination of pre-filter, mixed-bed cartridges, UV oxidation and a scavenger filter from permeate from a reverse osmosis system or deionized water.

The produced pure water can be tapped with a flexible dispenser, the withdrawal amounts from 0.1 to 99 liters with a flow rate of 8.0 l/min. The system has overflow protection and allows the unattended removal of the ultrapure water produced. To ensure consistently high ultrapure water quality, automatic recirculation takes place when no ultrapure water is taken from the system.


The pre-filter removes organic contamination from the feed water using activated carbon. The mixed-bed filterscartridges desalinate the water. The UV disinfection deactivates organic substances and the Scavenger cartridge filter removes these. This reduces the TOC content of the water and organic fouling is prevented. Finally, the water flows through an ultrafiltration module.


The device is available for different applications in the following three different TOC configurations:

< 10 ppb
life science
< 5 ppb
< 3 ppb
Automatic conductivity monitoring

The µS control at the inlet protects the downstream filter cartridges from unsuitable feed water by shutting off the water flow if the conductivity of the feed water is too high.

User Interface & Software

Process data from the ongoing preparation as well as warning messages are displayed on the touchscreen monitor. Process data from previous processing operations are stored up to 1 year retrospectively. The software includes a maintenance module and a self-diagnosis module, whereby service times< /span> and costs are reduced.

Frame / substructure

All the required components are installed on a frame system and are freely accessible from three sides and from above. Maintenance work can therefore be carried out very easily.

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 monitoring

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

Volumetrically controlled water delivery

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