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.
