A pH sensor (120) for a single-use bioreactor (51) is provided. The sensor (120) includes a pH sensing electrode (146), a reference system, a storage compartment (150), and an access mechanism. The reference system includes a reference electrolyte (142), a reference electrode (144) disposed in the reference electrolyte (142), and a reference junction (152). The storage compartment (150) contains a storage solution (160) that is configured to contact the pH sensing electrode (146) within the storage compartment (150). The access mechanism is configured to, when actuated, couple the pH sensing electrode (146) to an interior of the single-use bio-reactor (51). The storage solution (160) includes a buffer solution that is compatible with the reference electrolyte (142). |
