Optimum pure water production
Tap water is first purified to pure (Type 3) water by reverse osmosis (RO) using techniques designed and optimized by Millipore:
- Pre-treatment ProGard® cartridge validated to extend the lifetime of the RO cartridge
- Reject recirculation loop which recycles reject water treated by the Progard to minimize tap water usage and extend Progard lifetime while avoiding fouling or scaling issues that might shorten the RO cartridge lifetime.
- Unique system adaptation to feed water temperature in order to avoid flow rate decrease during the winter time when tap water is colder.
- Unique safety device ensuring that only low ionic permeate water will be sent to the tank in order to warrant adequate pure water quality and to increase the life time of the ion-exchange cartridge used to produce ultrapure water.
- Complete process monitoring system checking systematically water temperature, pressure, conductivity and RO rejection using calibrated meters at different steps.
The pure water produced by the Reverse Osmosis is stored in a tank designed to minimize risks of contamination during water storage. Millipore tanks level sensor will allow the systems to automatically start or stop producing water when you want it, display accurately on the systems screen the water level in the tank and have safety devices preventing overflow or system running dry.
From that reservoir, water can be sourced though a front valve or sent by a delivery pump to feed instruments such as a glassware washing machine, or further processed by the Milli-Q Direct to produce ultrapure (type1) water.
From pure water, the Milli-Q Direct produces ultrapure water adapted to your specific applications and exceeding the requirements of the most demanding norms.
We’ve achieved all this with a new purification strategy. Water is purified in a first step using unique Jetpore ion-exchange resin, synthetic activated carbon and UV lamp emitting at 185 and 254 nm to reach a resistivity of 18.2 MΩ.cm at 25 °C and a TOC value below 5 ppb, both monitored by advanced analytical techniques.
This water is sent through a small recirculation loop to the POD Pak, where a final purification step, critical for specific experiments, removes contaminants just before water leaves the system.
You can replace the ProGard pretreatment pack or the Q-Pak polishing cartridge in less than 5 minutes.
Total Water SolutionsWith Milli-Q Direct, you get more than just a lab water system: Millipore provides you with a total lab water solution including possible product evolutions such as upgrades, new consumables or accessories, quality assurance support (certificates of quality, calibration as well as qualification documents), service support as well as applications and scientific support so that you are sure to access 100% of the time water quality and quality adapted to you needs, even if they evolve with time.
