A disposable apparatus for cell expansion, having at least one bioreactor. The bioreactor has a cellular growth area and a supply area, the cellular growth area being separated from said supply area by a membrane. A fluid recirculation path in fluid communication with the cellular growth area allows for hermetically removing a sample containing cellular matter. This may comprise an elongated tube, or a plurality of parallel tube segments. The parallel tube segments have inflow ends and outflow ends, and the inflow ends are joined at a first common juncture and the outflow ends are joined at a second common juncture. The common junctures may comprise valves.
