Qualification of the aseptic core zone - Flow visualization

For a successful qualification of an aseptic core zone, a wide variety of points must be illuminated. A flow visualization, also known as a smoke study, is a crucial part of this qualification to understand the flow patterns in isolators, RABS systems and cleanrooms. It enables potential contamination or leaks to be identified and rectified. Various methods are used for visualization, which include the use of non-toxic smoke or special particles to make the airflow visible.
