ABSTRACT:
The present invention provides a device for rinsing out a substance present in a zone (d) with a liquid rinsing agent in several rinsing steps and for transferring the rinsing agent emerging from the zone (d) in the last rinsing step to a cuvette (K), wherein the zone (d) is present on a rotor (R) of variable speed of rotation, radially inwardly of the zone (d) on the rotor (R) there is provided a pump chamber (PK) for the rinsing agent which is connected with the zone (d) via a valve chamber (VK2) which fills, under the action of centrifugal force, above a predetermined speed of rotation, from the pump chamber (PK) and empties below the predetermined speed of rotation into the zone (d) and the zone (d) is connected with the cuvette (K) via a pipe (4) which, in one section, the axis of which has a component directed radially outwardly, is directed into a waste chamber (AK).
