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.
