ABSTRACT:
In a process for carrying out an analytical determination by mixing and incubating a sample liquid with at least one dry reagent which is soluble therein to form a reaction mixture liquid and measuring a parameter in the reaction mixture liquid, the sample liquid is first transported along a transport path to the soluble dry reagent and the resulting reaction mixture liquid then further transported along the transport path. The further transporting of the reaction mixture liquid along the transport path is under the influence of a force-change cycle in which centrifugal force and a further force alternately predominate to determine the direction of the further transporting along the transport path. At least one further liquid is transported on another path, part of which is separate from and part of which is common with the transport path, by the force-change cycle in such a manner that at least two of the liquids pass through the common part of the transport path chronologically separated.
