Water Purifiers

Milli-Q Integral 10
The Milli-Q Integral system includes a comprehensive and optimized sequence of water purification and monitoring technologies in a single unit, allowing both pure and ultrapure water to be produced directly from tap. It provides pressurized, bacteria-free water through E-POD (Elix-Point-of-Delivery) units and Milli-Q ultrapure water through Q-POD (Quality-Point-of-Delivery) units.

Water can be delivered from the system’s exclusive production unit to as many as 3 independent PODs that can be conveniently located at different places in the laboratory. Each POD incorporates a colour backlit screen enabling the user to check the operation of the entire system and the water quality at a glance.

The ergonomic design of the PODs accounts for the height and shape of regular laboratory glassware to ensure optimum user convenience. Water can be delivered at different flow rates from the mobile dispenser located at the end of an 80 cm recirculation loop. The user can also select a specific water volume and have the Q-POD/E-POD unit automatically fill any laboratory vessel from a 100 mL Erlenmeyer flask to a 5 L calibrated flask or 20 L carboy.

To ensure easy adaptation to various laboratory applications, validated POD Packs polishers are available to remove contaminants that can impact specific applications (such as pyrogens, nucleases, bacteria, particulates, organics, etc.) just before water leaves the system. Configurations can easily evolve to match lab activity changes or extensions.

  • Pure and ultrapure water is available directly from tap water (no need to have a DI source in the lab) from 60 L/day up to 350 L/day (depending on model)
  • Consistent production of superior quality pure water (better than twice the quality of distilled water) without the need to regenerate a DI tank, thanks to patented Elix technology
  • Easy pure or ultrapure water delivery in different lab locations thanks to the PODs
  • Easy and intuitive operation
  • Application-specific water qualities through customized final polishers
  • Built-in resistivity and TOC monitors designed to comply with the most demanding norms, including USP requirements (§ 643 and § 645)
  • System manager-specific interface with protection of key set points by a login and password

When the system is equipped with a 0.2 μm filter, the high purity water delivered by the system is suitable for HPLC, LC-MS, MALDI-ToF-MS, IC, ICP, AA and most of the analytical techniques commonly used in the laboratory. When an ultrafiltration cartridge (BioPak) is utilized at the point-of-use, the water is suitable for genomics applications (quality at least equivalent to DEPC-treated water) and cell culture. The water produced following the system’s pretreatment step may be used for basic laboratory needs, such as buffer and reagent preparation, microbiology media preparation, histology, dissolution testing (with UV detection) and rinsing of glassware.

Direct-Q 3 Ultrapure Type 1 Water System
Instant Flow Rate Above 0.5 L/min

The Direct-Q 3 systems are designed for simple and intuitive operation. Water quality parameters (resistivity or conductivity, temperature) are clearly indicated on a bright colour display. The Direct-Q 3 systems allow delivery of a fixed volume of Type I water and automatically shut off once the selected volume has been delivered.

The Type 1 product water is suitable for most low-volume laboratory applications, including the preparation of buffers for liquid chromatography separations and biochemical experiments, of solutions for analytical techniques such as spectrophotometry and spectroscopy, and of culture media.

For applications requiring very low organic contaminant levels, the Direct-Q 3 UV system also incorporates a dual wavelength UV lamp to produce water with <5 ppb TOC, making it suitable for HPLC, GC, ILC and TOC analyses. With the BioPak cartridge as a final filter, Direct-Q 3 systems produce pyrogen-free, RNase-free water for cell culture and molecular biology applications.

  • Produce Type 1 ultrapure water (18.2 Ω·cm resistivity at 25 °C an < 10 ppb Total Organic Carbon) on demand directly from potable tap water
  • Available with a built-in 185 and 254 nm UV lamp for production of low TOC water required by organic-sensitive applications
  • Produce Type 3 (Reverse Osmosis) water for basic lab applications at a flow rate of 2.4 L/hr at 15 °C. Type III water is easily available from the 6 L built-in reservoir
  • Maintenance reduced to a simple cartridge change once or twice a year. Ideal for laboratories that do not have easy access to pretreated water and need between 1 and 10 L of ultrapure water per day
  • Alarm warning in case of a sudden drop in the quality of the product water
  • Dispensing adapted to different size laboratory glassware.
  • Time-saving fixed volume dispense
  • Type 1 water for HPLC mobile phase preparation, sample dilution, buffer and cell culture media preparation, preparation of chemical solutions used with titrators, spectrophotometers and electrophoresis systems, preparation of culture media and reagents for molecular biology applications
  • Type 3 water for low-volume non critical applications such as glassware washing or rinsing

RiOs-DI 3 UV Water Purification Systems
Produce up to 10 litres of high quality analytical grade water (Type 2) per day from the tap. The RiOs-DI 3 UV system is a very compact solution that efficiently combines reverse osmosis technology with deionization resins to produce high quality pure water of high resistivity and low TOC (> 10 MΩ·cm and < 50 ppb). The system’s product water is stored in an internal reservoir and is ideal for low volume routine laboratory applications.

The unique simple plug-and-use purification pack enables the production of high quality (Type 2) water from tap water. To ensure reliable contaminant removal, the pump-assisted flow of tap water steadily reaches the cartridge, in spite of low pressure on the supply side or drop in water temperature.

  • Combining several purification technologies including Reverse Osmosis and Deionization, the RiOs-DI 3 UV system removes all types of water contaminants (typically >99 %)
  • The built in UV lamp* is ideal for applications that require low bacteria levels
  • The consumable is a “unique all-in-one” pack that includes the pre-treatment, reverse osmosis membrane and ion-exchange resin
  • Maintenance is reduced to the quick change of a single cartridge
  • Backlit colour display shows resistivity, temperature and water level in reservoir
  • Integrated, compact 6-liter reservoir


  • Buffer and reagent preparation
  • Microbiological culture media preparation
  • General washing
  • Feed to Milli-Q and Synergy ultrapure water systems

* This system is also available without UV lamp.

Select Purewater 300
Designed specifically for use with laboratory glassware washing machines, providing rinse water to a purity of over 1MΩ.cm at a flow rate of up to 48 litres per hour. The system is compact, robust, simple to use and easy to maintain, using proven pre-treatment, reverse osmosis and ion-exchange deionisation technology to ensure a reliable and consistent supply of purified water.

The unit has standard connections for quick installation with a high flow outlet that fits easily to most glassware washing machines using a conventional gravity feed. It incorporates a standard 20 litre integral tank or can be supplied with an optional external 50 or 100 litre tank for extra capacity. The Purewater 300 can also be supplied with an optional boost pump to ensure optimum performance at all times, especially in areas where incoming feed water pressure is below 4 bar.

Select Fusion
Purpose built for analytical and life science applications that need small volumes of ultrapure water to 18.2MΩ.cm from a mains supply, typically up to 50 litres per day, in addition to purified water for general laboratory use. The self-contained, dual quality system integrates pre-treatment, reverse osmosis, UV photo-oxidation, ion exchange and sub-micron filtration technology in a single, robust and compact enclosure.

The Select Fusion is also available with EDI technology replacing the more traditional ion-exchange treatment. A high contrast LCD shows system status, including water quality, TOC, temperature and flow rates. Visual and audible alarms are also included, while event data can be downloaded via a standard RS232 port.

The system provides take-off through either an ultrapure water dispenser or a separate bib tap. When it is not being used, water quality is enhanced by automatic recirculation. The Select Fusion can be wall or bench mounted and is supplied with an installation kit and a full set of consumables. An optional boost pump is also available for areas with <4 bar feedwater pressure.
