Disposable measurement arrangement and method of testing and/or calibrating said arrangement

摘要

A measurement arrangement comprising a flexible disposable container (101) and a disposable measurement probe (103) for measuring an analytical property of a medium, which is mounted on an inside wall of said disposable container (101) and comprises a sensing element (107) extending into the container (101), is described, which is ready to use and which produces reliable measurement results, said disposable measurement arrangement comprising: a closed capsule (109) containing a buffer solution and a tether (111) connecting said capsule (109) to said probe (103). The container (101), the measurement probe (103), the capsule (109) and the buffer solution are sterilized. The sensing element (109) is inserted in said buffer solution during storage and the capsule (109) is removed from the sensing element (109) during measurement operation.
