WFI (Water for Injection)

Water for Injection (WFI) is high-purity water specifically sterilized for medical and pharmaceutical use, particularly in preparing injectable medicines. It meets strict quality standards to ensure it is free of bacteria, endotoxins, and other contaminants. WFI is produced through rigorous purification processes such as distillation or reverse osmosis and is used in manufacturing drugs to ensure safety and effectiveness. Because it is intended for direct contact with sensitive medical products, its quality is tightly controlled and regularly tested to ensure it remains safe for patient administration.
