Hollow Fibre Bio Reactor
FiberCell® Systems USA

Duet Pump provides flexible flow rate support for all of the FiberCell® Systems hollow fiber bioreactor cartridges. Continuous flow is required to provide for nutrition support and constant oxygenation of the culture modules. The Duet utilizes a unique positive pressure displacement pumping action on the pump tubing of the flow path. Squeezing of the tubing in conjunction with the two one-way check valves produces a frictionless pumping action. Peristaltic pumps rub on the tubing causing pieces of the tubing to break off and move into circulation where they can cause blockage of the fibers. This frictionless mechanism is the reason that FiberCell® Systems modules have supported continuous culture of cells up to 2 years of continuous culture.
