Aquinity P35/P70

Short Overview

Aquinity² P versions produce deionised water (< 2 µS/cm/ < 0.5 MOhm x cm) by reverse osmosis and conditioning module in to the external reservoir (35 liter or 70 liter). The water can be tapped directly (e.g. for glassware cleaning by hand) or connecting the tank to a laboratory dishwasher. Out of the storage tank the ultrapure water is produced and then can be tapped with a flexible dispenser. The Aquinity² water purification system is available in different configurations (Reagent, Analytical & LifeScience) to meet the specific requirements of ultra pure water for different applications. Analytical is a version with UV lamp for low TOC value.

Life Science version comes with UV lamp and Ultrafiltration Module for low TOC and low endotoxin values. An optional integrated TOC sensor allows the user to monitor the TOC content permanentely online. Besides that the Aquinity² can be configured as bench top or bench-integrated system with external panel and wall mounted (with inclined display). The tank can be installed at the side or above the system or even underneath the bench. Upon request the tanks can be connected in series to reach a bigger volume of reservoir.

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.

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.

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.

Volumetric dispensing

Our dispenser 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.
