Water for Injection (WFI)
Water for Injection (WFI) by definition is water that is intended for use in the manufacture of medicines for parenteral administration whose solvent is water (WFI in bulk), or water that is used to dissolve or dilute substances or preparations for parenteral administration (heat-sterilized WFI). WFI in bulk from Biochrom AG is sterile-filtered and intended for in vitro use. WFI in bulk is suitable for use in the manufacture of media for biopharmaceutical production or for the manufacture of buffers. All solutions produced by Biochrom GmbH for cell culture and buffers are based on WFI in bulk water quality.
WFI in bulk is offered in single-use bags from 100 l. Biochrom GmbH also offers ultra-pure water in smaller fillings suitable for HPLC. It is produced from WFI in bulk and filled in PET bottles.
The validated primary packaging (sterile plastic bags for 100, 200, 500 or 1000 l for single-use) guarantees the required specifications for WFI with regard to the critical parameters of total organic carbon (TOC) and conductivity for at least 3 months.
