Sensor mount for using a conventional sensor with a single-use bioreactor while preserving the sterility of the single-use bioreactor

摘要

The invention relates to a bioreactor system (1), having: a pre-sterilized disposable bioreactor (2) having a reactor wall (20) which surrounds an interior (21) of the disposable bioreactor (2), the interior (21) for receiving a fluid medium (M ) is designed, a sensor (3), which can in particular be an unmodified standard sensor, wherein the sensor is designed to detect a gaseous analyte in the medium (M) or an analyte dissolved in the medium (M), wherein the sensor (3) has a sensor housing (30) with an external thread (31) and a sensor shaft (32), the sensor shaft (32) having a distal end portion (33) with an end face (34) having a for the analyte permeable region (35), one with the reactor wall (20) connected to the sensor receptacle (4) which is designed to receive the sensor (3) in such a way that the sterility of the disposable bioreactor (2) is maintained, the sensor receptacle hme (4) has a peripheral flange (40) via which the sensor mount (4) is fixed to the reactor wall (20), the flange (40) having a peripheral inner side (41) with an internal thread (42) into which the external thread (31) of the sensor housing (30) can be screwed in, and wherein the sensor receptacle (4) has a wall (43) connected to the flange (40) which, together with the sensor shaft (32), can be inserted into the interior (21) of the disposable bioreactor (2nd ) protrudes and separates the sensor (3) from the interior (21) when the sensor (3) is arranged in the sensor mount (4) and is screwed with its external thread (31) into the internal thread (42) of the sensor mount (4) as intended is.
