Impeller in bioreactor
WitrynaSome common geometries of laminar impellers are the ribbon impeller, the screw impeller, and the anchor impeller. Figure 1: Laminar Flow Impellers These … WitrynaCell-Lift impeller rotation creates a negative pressure in the hollow impeller tube causing medium to circulate uniformly in a closed loop. Cells and microcarriers are separated from the medium in the decanter column. The medium is harvested and the cells and microcarriers are transferred back to the bioreactor.
