Perfusion bioreactors for continuous cultivation | INFORS HT

Perfusion is a continuous culturing method in which cells are either retained in the bioreactor or fed back into it. The harvested medium thus contains no cells, resulting in higher cell concentrations and product yields in the reactor while still reducing the working volume. This also prevents the risk of cell washout due to excessively high dilution rates (D).
