Oscillatory baffled reactor

A Continuous Oscillatory Baffled Reactor (COBR) is a specially designed chemical reactor to achieve plug flow under laminar flow conditions. Achieving plug flow has previously been limited to either a large number of continuous stirred-tank reactors (CSTR) in series or conditions with high turbulent flow.
