A rotor unit for a centrifugal analyzer for analytically determining components of a sample, comprising: a rotatably driven circular rotor base; and a rotor head comprising a plurality of disposable insert elements and means for releasably mounting each insert element on the rotor base interchangeably at any one of a plurality of different selectable angular positions to positionally fix each insert element in place during rotation of the base and to enable the removal of each insert element after use, wherein the plurality of insert elements include at least one rigid sample analysis insert element for determining at least one sample component and having at least one first means forming a sample chamber for the reception of a liquid sample, at least one second means for forming a measuring chamber radially outwardly from the associated sample chamber when the sample analysis element is mounted on the base for the measurement of characteristic parameters during the rotation of a rotor head for the detection of components of a sample, at least one third means comprising means defining a plurality of interconnected hollow space and forming a liquid channel connecting the sample chamber with the measuring chamber and configured for an analysis to be carried out, and an analysis reagent in storage stable dry form positioned in the liquid chamber radially between the sample chamber and the measurement chamber for being mounted and removed with the analysis insert element and at least partly dissolvable by a sample to effect combination and mixing with a sample in response to the effect of centrifugal force before arriving at the measurement chamber.
