Cleanrooms are usually employed for clinical devices and a few tissue products. Isolators are usually useful for injectable and drug products which might be aseptically processed and possess a very low or no tolerance for a sterility examination failure.
Annual gowning certification can be demanded. During this method, microbiologists should adhere to rigorous aseptic gowning procedures, with RODAC™ agar plates used to sample distinct gown regions.
