Witryna15 kwi 2010 · Impellers in animal (mammalian and insect) cell culture bioreactors essentially have to meet the same tasks as impellers in other bioreactors. However, there are special features of both free suspension and microcarrier cell culture that lead to particular agitation conditions compared to the others. 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.
