Water for Injection (WFI)

Water for Injection (WFI) is used where water with high microbiological quality is required. The essential properties of WFI include:

  • Conductivity: < 1.1 µS/cm at 20°C
  • Bacteria: < 10 CFU/100 ml
  • Endotoxins: < 0.25 IU/ml
  • TOC: < 500 ppb
  • Appearance: clear, colorless and odorless liquid

The required water quality thus corresponds to the requirements for Highly Purified Water (HPW). However, the difference lies in the manufacturing process: For WFI, only the distillation process is permitted.
