Abstract

An analytical device for automated determining of a measured variable of a liquid sample, includes: a base module; a replaceable cassette connectable with the base module and having at least one liquid container connectable via a fluid line with a measuring cell and containing a reagent to be added to the liquid sample for forming a measured liquid; and a measuring transducer for registering measured values correlated with the measured variable for the measured liquid accommodated in the measuring cell. The cassette has, associated with the at least one liquid container, a fluid coupling apparatus having a primary component and a secondary component and serving for producing a connection of the fluid line with the liquid container.
