Water purification systems, Direct-Q® 3
Water Purification Systems Pure and Ultra Pure Water Systems
Direct-Q® 3 systems have been developed for simple, immediate use. Ultrapure Type I water is suitable for preparing buffers for liquid chromatography and biochemical experiments, and for analytical procedures such as spectrophotometry and spectroscopy. For applications that require very low values of organic impurities, the Direct-Q® 3 UV system includes a UV lamp with two wavelengths in order to produce water with a TOC content <5 ppb, which is suitable for HPLC, GC, ILC and TOC analyses. With the BioPak™ cartridge as a final filter, Direct-Q® 3 systems produce pyrogen- and RNase-free water at a flow rate of 0,2 L/min. Direct-Q® 3 systems are ideal for laboratories which do not have easy access to pre-treated water and require between 5 and 10 litres of ultrapure water per day. For the production of Type I and Type III water.

  • An integral timer makes it possible to dispense Type I water for a specified time period; the system switches off automatically when the set time has elapsed
  • An alarm is triggered when there is a sudden drop in the quality of the product water
  • Water quality parameters (resistivity or conductivity, temperature) are shown on a colour display
  • Maintenance consists of a simple pack replacement once or twice a year
  • Integrated, compact 6 litre reservoir for Type II water – connection to a 30 or 60 litre reservoir is possible for higher daily needs
  • Units can be bench or wall mounted (wall mount bracket required)

The systems’ versatile remote dispenser helps the user to stay focused on their work by providing ultrapure water delivery where needeed. The remote dispenser can be placed up to two metres from the Direct-Q® system and are available in free-standing or wall-installed models. Alternatively, systems in the Direct-Q® range are available with an integrated dispenser for use on the bench top.

Pure (Type III) product water quality (in regular operating conditions):
Ionic rejection >96%
Organic rejection for MW>200>99%
Bacteria and particulate removal >99%

Ordering information: A tank vent filter, a SmartPak™ DQ3 filter and either a Millipak® or BioPak® final filter have to be ordered with the unit.

Caution: * Type I purified water.
