Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.

Perfusion bioreactors for continuous cultivation | INFORS HT

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).
