An interface for coupling a dissolved oxygen sensor to a single-use bioreactor container is provided. A dissolved oxygen (DO) window membrane is operably coupled to the single-use container and configured to position a DO sensor at least partially within the single-use container. In some embodiments, a DO window body mounts the DO window membrane at a distal end thereof. The DO window body can include a slide lock for facilitating positioning of a DO sensor within the DO window body. Additionally, the DO window body may include at least one heat exchange fin.

Detachable dissolved oxygen sensor interface for single-use bioreactor/mixer

A flame arrester for a process device is provided. The flame arrester includes a flame arrester element formed of a first helix having a first axis and a second helix having a second axis, wherein the first axis and the second axis are unparallel. A housing configured to mount to the process device. The flame arrester element is mounted to the housing. A combustion analyzer employing an improved flame arrester is provided along with a method of manufacturing an improved flame arrester for process devices.

A multi-stage irreversible sensor coupling is provided. A sensor body includes a sensor and has a sensor body wall and at least one sensor body engagement feature. A clip barrel is configured to slidably engage the sensor body and has at least one clip barrel engagement feature. A wedge clip is configured to slidably engage the clip barrel and has at least one wedge clip engagement feature that is configured to urge the at least one sensor body engagement feature into cooperative engagement with the at least one clip barrel engagement feature when the wedge clip, clip barrel, and sensor body are fully engaged together.

Multi-stage irreversible sensor coupling

A pH sensor for a single-use container includes a plunger sleeve configured to couple to a flange of the single-use container. A plunger is axially movable within the plunger sleeve between a storage position and an operating position. A pH sensing element coupled to the plunger wherein the pH element is disposed within a storage chamber 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 is disposed within the pH sensor and configured to sense temperature proximate the pH sensing element. In another example, a lock member is coupled to the plunger, where the lock member has a locked position and an unlocked position, the lock member being configured to inhibit movement of the plunger when in the locked position. In yet another example, the plunger includes at least one filling channel that allows access to a reference fill chamber when the plunger is in a filling position.
