                                  Detailed introduction

                                  Direct-Q® systems deliver both RO (Type 3) and ultrapure (Type 1) water directly from tap.

                                  With the Direct-Q® range of water purification systems, you benefit from a choice of ultrapure water configurations. All systems produce Type 1 water (18.2 MΩ•cm at 25 °C ultrapure water) on demand from the RO stage, the first step in the purification chain. Depending on daily volume needs, different RO production flow rates are available (3, 5 & 8 L/h). Type 3 water is easily available from the 6L built-in storage tank, or the external 30/60 L storage tanks for the higher flow rates, or can be sent by a distribution pump to feed instruments such as a glassware washing machine.

                                  For applications sensitive to organic contaminants and requiring ultrapure water, a UV version of the Direct-Q® system is also available. It incorporates a dual wavelength UV lamp for photooxidation of organic compounds. A final purification step at the point-of-dispense removes specific contaminants critical for your experiments. A range of purification cartridges and Application-Paks is available for you to select according to your requirements.

                                  Simple handling & maintenance

                                  ·         Easy installation anywhere in your laboratory with its compact design and optional remote dispenser. Either wall-mounted, on or under the bench, choose the setup that is most convenient for your daily work. 

                                  ·         Dispensing adapted to different size laboratory glassware at an instant flow rate of 0.5 L/min. 

                                  ·         Save time thanks to the volumetric function. It will automatically deliver the water volume that you requested. 

                                  ·         Easily insert your pack in one movement with the patented locking mechanism.
