Question

What is the difference between wfi and purified water?

Answer 1

Water for injection has the highest purity possible and it is sterile. WFI is condensed and is generally kept at 80 - 90 ºC to maintain its properties. The main difference between a PW and a WFI loop is that the purified water is held at room temperature while the WFI is kept at 80-90oC.

Answer 2

Answer:

Explanation:

The main difference between a PW and a WFI loop is that the purified water is held at room temperature while the WFI is kept at 80-90oC. In fact, it means that a loop heat exchanger must be used to cool and heat the PW (during the sanitation process) and to heat and maintain the temperature of the WFI.
