Single-use pH sensor for bioreactor applications
A pH sensor (100) for a single-use container includes a plunger sleeve (114) configured to couple to a flange (102) of the single-use container. A plunger (134) is axially movable within the plunger sleeve (114) between a storage position and an operating position. A pH sensing element (142) coupled...

| description | A pH sensor (100) for a single-use container includes a plunger sleeve (114) configured to couple to a flange (102) of the single-use container. A plunger (134) is axially movable within the plunger sleeve (114) between a storage position and an operating position. A pH sensing element (142) coupled to the plunger (134) wherein the pH element (142) is disposed within a storage chamber (162) in the storage position and is configured to be exposed to an interior of the single-use container in the operating position. In one example, a temperature sensitive element (164) is disposed within the pH sensor (100) and configured to sense temperature proximate the pH sensing element (142). In another example, a lock member (120) is coupled to the plunger (134), where the lock member (120) has a locked position and an unlocked position, the lock member (120) being configured to inhibit movement of the plunger (134) when in the locked position. In yet another example, the plunger (134) includes at least one filling channel (156) that allows access to a reference fill chamber (154) when the plunger (134) is in a filling position. |
