Water for Injection (WFI) Quality Water
High-purity water used for the preparation of cell culture media, buffers, and aqueous reagents.
ILC Dover’s WFI Quality Water is produced in a cGMP-compliant, US-based facility and meets monographs for pharmacopoeias around the world, including US Pharmacopeia (USP), European Pharmacopoeia (Ph. Eur.), and Japanese Pharmacopoeia (JP). WFI Quality Water can be provided in standard and custom packaging up to 200 L or filled directly into specified packaging. Sterile WFI is available in up to 1 L packages. Through a distillation still combined with upstream purification and 0.1 μm filtration, intrinsically safe WFI is created with significantly less risk than other production methods.
