Abstract: A pH sensing bioreaction system is provided. The system includes a bioreaction container (51) having a plastic wall (50) and a pH sensor (40, 60, 80, 100, 120) attached to the plastic wall (50). The pH sensor (40, 60, 80, 100, 120) includes a sensor body (82) having a flange (76) that is sealingly attached to the plastic wall (50). The sensor body (82) has a reference electrolyte (142) therein and a first sensing element (152) disposed in the reference electrolyte (142). The first sensing element (152) is configured to contact both the reference electrolyte (142) and a sample solution (52) inside the bioreaction container. A second sensing element (62, 92, 148) is positionable into an interior of the bioreaction container (51). The pH sensor (40, 60, 80, 100, 120) has a plurality of configurations that include a booted configuration in which at least one sensing element is isolated from the interior of the bioreaction container (51), and a service configuration in which the at least one sensing element is fluidically coupled to the interior of the bioreaction container (51).

Abstract: A contacting-type conductivity sensor (10) includes an electrically-insulative plastic body (20) and a plurality of electrodes (12, 14, 16, 18). The plurality of conductive electrodes (12, 14, 16, 18) is disposed in the plastic body (20). Each electrode (12, 14, 16, 18) is constructed of plastic and fused with the electrically-insulative plastic body (20). A method of manufacturing the conductivity sensor is provided along with a single-use bioreactor (50) employing the sensor (10).
