What is Deionized Water?
Deionization ("DI Water" or "Demineralization") simply means the removal of ions.
Ions are electrically charged atoms or molecules found in water that have either a net negative or positive charge. For many applications that use water as a rinse or ingredient, these ions are considered impurities and must be removed from the water.
Ions with a positive charge are called "Cations" and ions with a negative charge are called "Anions". Ion exchange resins are used to exchange non desirable cations and anions with hydrogen and hydroxyl, respectively, forming pure water (H20), which is not an ion.
How does ion exchange work?
Ion exchange resins are used to produce deionized water (demineralized water or "DI Water") . These resins are small plastic beads that are composed of organic polymer chains that have charged functional groups built into the resin bead. Each functional group has either a fixed positive or negative charge.
Deionized water applications:
Required for critical laboratory applications such as HPLC, Mobile Phase Preparation, blanks and sample dilution for analytical techniques such as GC, HPLC, AA, ICP-MS, etc. Preparation of buffers and media for mammalian cell culture and IVF. Production of reagents for molecular biology applications (DNA sequencing, PCR). Preparation of solutions for electrophoresis and blotting.
Used in buffers, pH solutions and microbiological culture media preparation and for preparation of reagents for chemical analysis. Used in clinical analyzers, cell culture incubators and weatherometers, etc. Also used as feed water to Type 1 systems.
Used for glassware rinsing, filling autoclaves and heating baths and humidifiers. Also used as feed water to Type 1 systems.
Usually deionized ultra-pure water packaged in pharmaceutical grade plastic and the industry standard CFDPLAS Cubitainer with spigot. 2.5 gallon 10 litres cubitainer and 5 gallon 20 litres cubitainers.
Cubitainersare low-density flexible polyethylene cube-shaped inserts inside a heavy-duty corrugated outer carton (32 ounce does not include carton). Easy to ship, handle and pour. Designed to collapse as product is dispensed. The non-glug design assures product flow in a continuous, uninterrupted stream. A reversible well design permits opening to be raised or depressed for pouring and storage. Cubitainers are convenient for shipment and storage of liquid chemicals, from 1 quart to 5 gallons. Formed from low density polyethylene with injection molded caps.
