Impact of Agitator Design on Bioreactor Performance
May 15th 2018Aerobic bioprocesses are highly dependent upon the oxygen transfer rate (OTR) from sparged to dissolved gas. The relatively low solubility of oxygen, however, makes the choice of mixer impeller configuration a critical design factor for the bioreactor vessel. This article describes a series of experiments and computational fluid dynamics (CFD) simulations to detail the effect of mixer configuration on the efficiency and effectiveness of a bioreactor vessel with respect to blend time and mass transfer.
Six Sigma and the Path to Quality
October 2nd 2017Lawrence Yu, deputy director of the Office of Pharmaceutical Quality (OPQ), Center for Drug Evaluation and Research (CDER), and his FDA colleague, Michael Kopcha highlight the importance of Six Sigma approaches to continuous improvement in the pharmaceutical industry.
