This novel device is a stand-alone ultrapure water system, combining intuitive handheld monitoring and accurate pure water dispensing in a single, compact product. Compared to competing devices, the Purelab flex features a considerably smaller footprint. A hose with a distinctive colour and form allows continuous cycling and permanent monitoring of the water. With five global patents, it is designed to fit all laboratory environments that place high hygienic and technical demands on their equipment. Handling of the unit follows a clearly structured pattern and allows for precise control, even for gloved users. Compared to a throwaway commodity, the innovative character of this device becomes apparent with regard to cost and waste, both of which are considerably lower – both saving money and protecting the environment. The design of the Purelab flex, with the curved line of its hose, alludes to the flowing movement of water. This establishes a connection between the device and the product it processes, while simultaneously setting a visual accent in the often sterile laboratory environment.
