Sterility testing is list of activity to verify that solutions are totally free from any Viable Microorganism. Sterility could be outlined as absence of viable Microorganism.
Filters might not be adjusted after Each individual batch is sterilized. Identify if there is knowledge to justify the integrity on the filters for the time durations used and that "expand as a result of" has not transpired.
