Mediatech's Distilled Deionized Water, Cat.No. 23-25-055, is water for injection quality; it meets the USP testing requirements for Water For Injection, though it is not meant as an injectable. WFI quality water has applications in cell and tissue culture, cleaning of laboratory glassware and containers, device processing, process validation, and purification.

Raw water is run through mixed beds to remove gross impurities, then reverse osmosis filtration and deionization through cation and anion beds followed by distillation. Once the water is produced and it meets conductivity standards, it goes to a jacketed holding tank where it is kept at a minimum of 65°C to reduce bioburden and maintain low endotoxin levels. Product for sale is cooled to 30°C or below and sterile filtered through a 0.2 micron PES filter into a sterile holding tank where it is then filled into bags or bottles.

The following tests are performed prior to release: pH, ammonia, calcium, carbon dioxide, chlorides, sulfate, oxidizable substances, endotoxin, and sterility. The product contains very low chlorine, cation, and endotoxin levels. Tests for conductivity and total organic carbon (TOC) prior to packaging meet the current USP testing requirements for WFI quality water.
