ABSTRACT An insert element for use in a rotor unit of a centrifugal analyser for the analytical deter- mincation of at least one component of a sample fluid comprises a housing containing at least one sample chamber for the reception of a sample liquid, at least one measuring chamber for the measurement of characteristic parameters for the detection of com- ponents of the sample, while the element rotates with the rotor unit, and a fluid connecting channel communicating each sample chamber with an opposed measuring chamber; the housing has retaining means adapted to cooperate with a rotor base of the rotor unit such that the housing is adapted to be held positionally stable on the rotor base when the centrifugal analyser is in operation, with the at least one measuring chamber disposed radially out- wardly of the at least one sample chamber; at least one analysis reagent is disposed in the channel between the sample chamber and its opposed measuring chamber, such that in operation a sample liquid in a sample chamber is brought into contact with, and mixed with, the analysis reagent in the channel, under the action of centrifugal force before it reaches the opposed measuring chamber; the insert element in conjunction with the rotor unit of a centrifugal analyser provides a unit of simple operation with flexible and wide use.
