Purified Water (PW)

Pharmaceutical-grade water for non-parenteral uses, such as oral and topical products, cleaning and feed for WFI generation. It is usually produced by reverse osmosis and electrodeionisation from potable water, and must meet conductivity and TOC requirements. The typical microbial action level is 100 CFU/mL. PW systems are monitored at points of use and trended, and controlled by circulation, UV and periodic sanitisation.
