Milli-Q® Direct Water Purification System
Pure and ultrapure water directly from potable water at a flow rate of 16 L/hr.an all-in-one system that delivers pure and ultrapure water directly from tap water. The system:
- Delivers quality: Exceeds the requirements of the most demanding norms.
- Offers convenience: Manual and volumetric water dispensing at low and high flow rate.
- Has a low footprint: Wall or bench-integrated installation.
- Allows low running costs. Pure water: Tap water is first purified to Type 3 water by reverse osmosis (RO) techniques. Progard® cartridge protects the RO membrane, increasing its lifetime. High recovery RO minimizes tap water usage by maintaining water quality and a constant flow rate. Bactericidal UV lamp (optional) reduces risk of bacterial contamination. RO water is stored in a polyethylene (PE) tank designed to minimize risks of contamination during water storage. Vent filter provides effective protection against airborne contaminants Automatic Sanitization Module (ASM, optional), prevents bacterial growth and biofilm formation inside the storage tank Pure water can be either sourced through the tank front valve or sent by a distribution pump to feed instruments such as a glassware washing machine, or further processed by the system to produce ultrapure (Type 1) water. Ultrapure water:
- RO water is purified in the first step using unique Jetpore® ion-exchange resin, synthetic activated carbon and a photooxidation UV lamp to reach a resistivity of 18.2 MO.cm at 25° and a TOC value below 5 ppb; both values are monitored by advanced analytical techniques.
- The water is then passed through a recirculation loop to the Application-Pak, where a final purification step, critical for specific experiments, removes contaminants just before water leaves the system.
Application:
- The Milli-Q® Direct system delivers ultrapure (Type 1) water, recommended for critical laboratory applications such as HPLC, GC, GF-AAS, and other advanced analytical techniques. It can also be used for molecular biology (PCR,.) and biochemistry. It is also used in mass spectrometry tissue imaging.
- The system also delivers pure (Type 3) water is the lowest laboratory water grade, recommended for glassware rinsing, heating baths and filling autoclaves, or to feed ultrapure (Type 1) lab water systems.
