Abstract: A measurement arrangement comprising a flexible disposable container and a disposable measurement probe for measuring an analytical property of a medium. The measurement probe is mounted on an inside wall of the disposable container and comprises a sensing element extending into the container, which is ready to use and which produces reliable measurement results. The disposable measurement arrangement comprises a closed capsule containing a buffer solution and a tether connecting said capsule to said probe. The container, the measurement probe, the capsule and the buffer solution are sterilized. The sensing element is inserted in the buffer solution during storage and the capsule is removed from the sensing element during measurement operation.

Abstract: A pressure measurement arrangement for measuring a line pressure of a product is described wherein product hold-up inside of disposable parts is minimized, comprising: a reusable pressure sensor comprising a measurement diaphragm, a fitting, the fitting comprising: a tubular opening extending through said fitting, for the reception of a disposable elastomeric tube, an aperture extending through an outside wall of the fitting into the tubular opening; and mounting structure, for mounting the pressure sensor on the aperture, such that the measurement diaphragm is exposed to an inside of the tubular opening; wherein the disposable tube is inserted in the tubular opening of the fitting during measurement; and an outside wall of the disposable tube comprises a thin flexible portion, which conforms to the measurement diaphragm when the disposable tube is pressurized by the line pressure.

Abstract: A sterile measurement device comprising an elongated measurement probe for measuring a physical property. The probe has a first end and a second end, and a sensing element, which is located on the first end which can be installed at any time on a measurement site. The measurement site has a measuring chamber for measuring a physical quantity inside the measuring chamber without breaching sterility of the measurement arrangement. The measurement device further comprising a sterile tubing comprising a first end, a second end and a compressible section located between the ends. The sterile tubing surrounding the probe, such that the second end of the probe extends out of the second end of the tubing, structure for establishing a sterile connection between the first end of the tubing and a corresponding counter part on a measurement site.
