"We've been using the AquaRO² 10 DI for about 6 months now and have no problems at all. We installed the system by ourselves. It's plug and play and everything is described in the manual. We use it for laboratory analysis and for a dishwasher to clean the instruments we use. The AquaRO² 10 DI comes with a 35-liter tank which is mainly used for the dishwasher. A small pump under the sink in a cupboard provides the pressure for the dishwasher when it's used, the pump is not hearable, it's really quiet and doesn't bother the employees in the laboratory. Customer service is also good, you just write an email with your needs and they reply fast to help you out."

"We have used the Aqua RO² since 2018 for laboratory analysis and our lab dishwasher. It's stable and the water quality fits perfectly with our requirements. We had some minor issues with the pump, but the service department reacts fast and within 48 hr the problem was solved. All in all, it’s a good value for money

Designed for the production of pure water out of tap water

  • The series of AquaRO², AquaRO²DI and EDI² are based on a reverse osmosis (RO) unit to produce deionised water. 
  • The EDI² series further processes the osmosis water by using an EDI cell to get Type II water. All sytems provide you with reliable and compact systems at low operating costs. 
  • The advantages of both series is the flexibility in terms of configuration. A production rate of 8 to 40 L/h in three different degrees of pure water (10 µS/cm to 0.2 µS/cm) is available. Optionally the systems can be equipped with a dispenser. 
  • The customer can select a 35 L, 70 L or individual tank size.
Pure Water System: AquaRO² & EDI²

Main technical specifications of the system​


The scheme shows the setup of an AquaRO² DI with a capacity of 10 or 20 L. 

Flowchart: AquaRO²
Options Bench mount Aquinity

Bench integrated configuration (BI version)

To save valuable benchtop space the system can be ordered as BI configuration. The system will be installed underneath the work bench and only the display and dispenser are mounted on the wall.

Options: Wall mount Aquinity

Wall mounted configuration

To save valuable benchtop space the system can be ordered as wall mounted configuration. the whole system can be mounted on the wall with inclined display.

Options: External pump Aquinity E35 / 70

External pump

Compact pump is required when feeding laboratory equipment such as autoclaves or laboratory dish washers.

Optioins: TOC Monitoring Aquinity P10

TOC- Monitoring (TI Version)

The TOC monitoring during production and intermittent measurements during non-use periods allows to check the organic content in water continuously. The TOC value is measured between 1 and 999 ppb and can be shown in the display to monitor organic impurities.

Options: memTap Aquinity P10

Volumetric dispensing

Our dispenser for the series of AquaRO² 8 P10 allows the volumetric controlled dispensing of water with an increment of 0.1 L and a tap volume from 0.1 to 99 L. The system prevents overflow of containers and allows to dispense water without supervising.

Options: External tank AquaRO² & EDI²

Additional tank

The series of AquaRO² and EDI² can be equipped with a tank of 35 L or 70 L or individual size (up to 500 L) and if requested also with an integrated UV lamp. An exception is the AquaoRO² 8 P10 with an integrated tank of 10 liters.

Options: IQQ Documents Aquinity P10

IQ/OQ documents

Validation documents for water purification systems.

Both systems are laboratory water systems which provide the user with different qualities of pure water for a wide range of analytical and laboratory applications.

These systems are AquaRO² systems with an integrated 10 L tank that holds the treated water and then makes it available to the user via a dispenser.

Depending on the configuration, an AquaRO² system produces pure water with an electrical conductivity of between 0.2 and 10 µS/cm, while the EDI² systems achieve a value < 0.1 µS/cm. Most systems are fed with drinking water.

The compact design means that each of the systems takes up very little valuable laboratory space, and their simple and intuitive operation makes them easy to integrate into everyday laboratory work.

Customers have the option of selecting a system with a production capacity of 10 to 40 liters per hour, depending on the application and water requirements.

Due to the simple and clear design of the software, the user can quickly operate the device through intuitive handling. The software informs the user when limit values have been exceeded or when consumables such as cartridges or UV lamps need to be replaced. A wizard guides the user through the individual steps.

In addition to the hoses for inlet and outlet, an adapter is also included in the scope of delivery, which makes it easy for them to adapt the systems with the drinking water connection or to an inlet with pre-treated water.

Depending on the choice, the systems can be supplied with a 35 or 70 liter tank. There is also the possibility to offer tanks with a capacity of 100 L to 500 L. Each tank has a bottom outlet so that external systems such as analyzers or ultrapure water systems can be fed directly. On request, a booster pump can also be offered to pump the water.

The installation location can be designed very flexibly. Depending on the available work surface, the system can be integrated directly on the equipment, on the wall or under the lab bench. The display, which can be installed flexibly, also ensures convenient operation.
