Milli-Q Academic

The Milli-Q Academic water purification system utilizes the standard three-steps purification process - pretreatment, application specific polishing and final filtration - to produce Type 1, reagent-grade water suitable for all general laboratory applications.

The successful production of high-purity water depends on the careful integration of system design, purification processes, and periodic maintenance for control of water quality parameters. Milli-Q systems include a high-precision resistivity meter to measure trace ionic contaminants.

A three-step purification process and periodic recirculation of water ensure delivery of high-purity water immediately upon demand. Millipore systems also include a backlit, integrated display that allows for water quality monitoring and tracking of system maintenance requirements. Components of Milli-Q systems are constructed of clean, high-purity materials to minimize extractable contaminants.

Q-Gard1 is recommended for water pre-treated by Elix, RiOs systems or distillation. It contains high quality Jetpore mixed-bed ion-exchange resin and Organex.

Q-Gard 2 is recommended for deionized water. It contains a microfilter for particulate removal, activated carbon for organics adsorption and mixed-bed ion-exchange resin for ion removal.

Q-Gard 3 is recommended for deionized water with a high fouling index, i.e. with a high concentration of colloids (such as colloidal silica), articulates and organics. It contains macroporous ion-exchange resin that has less sensitivity to fouling but also lower ion-exchange binding kinetics and capacity.

Quantum application specific cartridges remove ionic and organic contaminants down to trace levels: select the Quantum IX cartridge to achieve trace levels of ionic contaminants; the Quantum EX cartridge for trace levels of ionic and organic contaminants; or the Quantum VX, if the application requires ultra-low levels of volatile organic contaminants.

Final purification of ultrapure water is carried out at the point-of-use by a pharmaceutical-grade, absolute 0.22 μm Millipak membrane filter that is recommended for most analytical applications.

Milli-Q Academic is available as a stand alone system, but can also be connected t to a remote point of water delivery with water recirculation to the delivery point and a built-in water quality indicator.
