Abstract: A flow cell for use in a fluid management and/or processing system is disclosed, said flow cell comprising a body having an inlet and an outlet and a fluid flow channel extending from the inlet to the outlet. Said body further comprises a receptacle comprising a chamber forming a part of the fluid flow channel, said chamber comprising a first opening for connecting a functional element to the flow cell such that the functional element is in contact with or exposed to a fluid flow passing through the fluid flow channel. A first tubular connector is arranged adjacent to the inlet. A second tubular connector is arranged adjacent to the outlet. The flow cell further comprises a functional element and a fluid flow path extending from the first tubular connector through the inlet, the body, the receptacle, and the outlet, to the second tubular connector.
