System for detecting at least one presence of foam of a medium in a bioreactor plant, wherein the system comprises: —a bioreactor plant having at least one disposable container for receiving the medium that may comprise the foam; and—at least two capacitive sensor units which are attached at at least two different situating positions of the bioreactor plant, wherein the capacitive sensor units each comprise at least one electrode system for capacitive measurement and are able to detect the presence of foam at the at least two situating positions on the basis of the capacitive measurement; and wherein the capacitive sensor units are designed to transmit captured data relating to the presence of foam to at least one monitoring unit for monitoring, open-loop and/or closed-loop control of foam formation in the bioreactor plant on the basis of said data.

Detecting foam in a bioreactor plant

Summarizing the invention, a sensing element for monitoring the state of a single-use sterilizable element such as a single-use bioreactor, wherein the state of the single-use sterilizable element is determined by at least one environmental condition is provided. The sensing element comprises: a variable component having at least one physical property that is configured to change in response to the at least one environmental condition and/or a change thereof, wherein the variable component comprises a sensing material with changing absorption characteristics for electromagnetic radiation configured to change in response to the at least one environmental condition and/or a change thereof.

A bag for containing a biopharmaceutical product includes at least one fluid input/output port and a measurement opening remote from the fluid port. A probe holder port has a body with an axial through-bore and a peripheral collar with a second fastening zone and defining a fastening plane. A contact probe, extending in the axial through-bore, is assembled on the probe holder port, has an active measurement end portion in contact with the product, and has an end portion opposite the end portion. The probe holder port includes a transition portion between the body and the collar, which extends between a radially central end portion of the collar and a first axial end portion of the body. The first axial end portion is the axial end portion closest to the radially central end portion of the collar. The first axial end portion is disposed on the outer side relative to the fastening plane, and the active measurement end portion is axially disposed on the outer side relative to the fastening plane.
