Cell Culture Scale-Up in Stirred-Tank Single-Use Bioreactors
www.eppendorf.comThe stirred-tank bioreactor design is relatively easy to describe with classical engineering approaches (Figure 1). Parameters to describe this vessel geometry include impeller diameter, vessel diameter, liquid height, and ratios thereof. It is the bioreactor design for which most research on Figure 1: Stirred-tank bioreactor design d D i h ...

www.egr.msu.edua continuous flow reactor, the feed to reactor and the discharge from it are continuous. The three types of continuous flow reactor are plug flow reactor, the dispersed plug flow reactor, and completely mixed or continuously stirred tank reactors (CSTRs). CSTR consists of a stirred tank that has a feed stream and discharge stream.

Distributions of Residence Times for Chemical Reactors
websites.umich.eduIn many continuous-stirred tank reactors, the inlet and outlet pipes are close together (Figure 13-3). In one operation it was desired to scale up pilot plant results to a much larger system. It was realized that some short cir-cuiting occurred, so the tanks were modeled as perfectly mixed CSTRs with a bypass stream.

BioBLU c and BioBLU p Single-Use Vessels for cell culture
www.eppendorf.comstirred-tank single-use vessels have been specifically designed and optimized for cultivation of mammalian cells. The BioBLU 5p vessel is a packed-bed bioreactor perfectly suited for adherent cells and perfusion culture. Pre-loaded with Fibra-Cel® disks, it provides a solid support growth matrix, e.g. for production of secreted proteins.
