Our solution: the Direct-Q® range of
water purification systems
Direct-Q® systems deliver both pure and ultra-
oure water directly from tap for use with a wide
variety of applications in your lab.
With the Direct-Q® range of water purification
systems, you benefit from a choice of ultrapure
water dispensing possibilities. The innovative,
space-saving Remote dispenser offers you water
delivery solutions to best fit the way you work,
with easy and convenient remote delivery up
to two meters away from your water production
unit.
The Direct-Q® range includes versatile solutions
that can be bench-integrated or bench- / wall-
installed.
Direct-Q® systems come either with an integra-
ted 6-liter reservoir or an external reservoir (30
| or 60 I).
Systems in the Direct-Q® range provide 3, 5 or 8
liters of pure water per hour, covering lab needs
of 50,100 and 150 | of pure water per day.
Direct-Q® systems dispense up to 30 | of
ultrapure water per hour.
Options such as a UV lamp and a range of
Application Pak point-of-use polishers are
available to fine-tune your ultrapure water.
The user-friendly display provides system status
at a glance; the concise Quick Reference Guide is
a handy guide for daily operation.
All-in-one SmartPak® cartridges enable easy
and rapid replacement.

Choose the solution that's right for you
Easy installation
The Direct-Q® range of systems requires no special
installation. You can easily set the system up yourself:
just connect the system to your tap water supply, plug
it in, and insert the SmartPak® purification cartridges.
Then, if your configuration includes the Remote
dispenser or a 30- or 60-liter reservoir, follow the
simple setup procedures — and your system is ready to use!
Optimized lab space
The compact, all-in-one Direct-Q® water purification unit
lets you locate it nearly anywhere in your laboratory,
either on or under the benchtop, or wall-installed.*
*Direct-Q® 5 and Direct-Q® 8 systems are designed for use with a 30 | or 60 |
external reservoir.
Flow rates to match your requirements
Choose the solution that best meets your lab's requirements with a Direct-Q®
system that provides 3, 5, or 8 liters of pure water per hour, and more than 0.5 |
of ultrapure water per minute (> 30 I per hour). When not in use, the Direct-O®
system automatically recirculates water in order to maintain high water quality,
so that you do not have to wait when sourcing ultrapure water. For your conve-
nience, and to save time, you can also set the system to automatically deliver
your selected volume of ultrapure water on demand.
Choice of storage volumes
With its built-in reservoir, the Direct-OQ® 3 system can store 6 | of reverse
osmosis (RO) water, while Direct-O® 5 and 8 models are designed for use with a
30- or 60-liter reservoir. Just choose the storage volume that best meets your
daily water volume needs.
Fine-tune your water quality
Both pure and ultrapure water
The Direct-O® range of systems provides you with a convenient and flexible
solution for your pure and ultrapure water needs, directly from potable tap
water. You'll have access to ultrapure water for your critical applications, and
pure water for less critical applications such as general glassware washing or
final rinsing — from the same system!
The high quality ultrapure water produced by Direct-Q® systems is suitable for
applications such as production of mobile phase for chromatographic separations;
preparation of blanks and standard solutions for spectrophotometry, spectroscopy
or other analytical techniques; and preparation of buffers for biochemical
experiments.
Organic-sensitive applications
Direct-O® systems are also available with a built-in 185/254 nm UV lamp to
reduce the level of organics for critical applications. Water with low
TOC provides important benefits to HPLC users such as higher sensiti-
vity and longer column lifetime. The same UV lamp also destroys bacteria.

Application Pak point-of-use polishers
Merck Millipore's range of Application Pak polishers makes it possible to
fine-tune your ultrapure water quality to match your research needs. Are your
applications sensitive to bacteria, particulates, pyrogens, nucleases, endocrine
disruptors or Volatile Organic Compounds? If so, just choose the appropriate final
polisher from our range of Application Paks to provide optimal water quality
for your requirements.
Please see www.millipore.com/laobwater for more information.
Stay focused on your work
Versatile remote dispenser
Designed to fit perfectly into your lab environment, the versatile Remote
dispenser can be placed up to two meters from your Direct-Q® water purification
unit. Select the free-standing or wall-installed model according to your
needs — their ergonomy will make either one a welcome addition to your lab,
giving you the freedom to focus on your research, while dispensing ultrapure
water exactly where you need it. Alternatively, Direct-OQ® systems are also
available with an integrated dispenser for use on the benchtop.
The design of the bench-installed Direct-O® systems is also adapted to the
height and shape of common laboratory glassware.
Merck Millipore offers
