Patent ID: 8304231

Claim:
A bioreactor, comprising a reactor vessel ( 2 ) with a receiving port ( 20 , 20 a ) that extends into an interior ( 14 ) of the vessel in medium-tight fashion against the vessel interior ( 14 ), comprising a transparent sensor piece ( 34 , 34 a ) with an indicator tile ( 38 , 38 a ) arranged in the vessel interior ( 14 ) in contact with contents of the vessel, which indicator tile may be scanned by a fiber optic that may be introduced into the receiving port ( 20 , 20 a ) and is contacted to a display device ( 24 ), wherein the reactor vessel is embodied as a bag, wherein the receiving port ( 20 , 20 a ) is arranged at an upper side of the reactor bag and is provided with a flange piece ( 26 ) tightly sealed to the vessel wall ( 28 ), the receiving port including means for securing the inserted fiber optic and the receiving port being connected to the sensor piece ( 34 , 34 a ) via a tubular connector piece ( 32 , 23 a ) in such a way that the sensor piece ( 34 , 34 a ) reaches into the reactant from above, wherein the sensor piece ( 34 , 34 a ) comprises an end portion with a bottom ( 40 ), wherein the bottom ( 40 ) is incorporated within a cap ( 42 ) that encloses the end portion, and wherein the reactor bag can be clamped at two opposite sides ( 4 ) thereof to a support ( 12 ), wherein the receiving port ( 20 , 20 a ) is arranged in a central region of the reactor bag, ensuring that the sensor is always in contact with the reactant even during oscillating movements imparted to the bioreactor during a reaction process, the bioreactor further comprising an analogous second receiving port ( 20 a ) that is parallel to the first receiving port ( 20 ) and comprises an indicator tile ( 38 a ) for an insertable fiber optic ( 22 a ) for determining a further property of the react an wherein a second sensor piece is connected to the second receiving port, and further comprising a clamp that holds the sensor pieces together in parallel.
