The EnviroCam Zenith-BL3 is an in situ vision analysis system used in the Biotechnology Industry. EnviroCam "PAT" applications include bubble analysis, and the characterization of bioreactors for Kla calculations.

Process Analytical Technology "PAT" has been defined by the Food and Drug Administration as a mechanism to design, analyze and control pharmaceutical manufacturing processes through the measurement of critical process parameters and quality attributes.

It has been said that one of the challenges with "PAT" is knowing where and how to start. In Biotechnology, an easy and effective way to start is to utilize the EnviroCam to accurately measure and analyze the gas bubbles produced by the sparger. It is well known that bubble size and distribution effect cell growth during the batch.
