ABSTRACT OF THE DISCLOSURE A device is provided for the control and mixing of a fluid current subjected to centrifugal force in an element rotating about an axis, especially the rotor of a centrifugal analyser, the amount of fluid to be con- trolled having a limited volume wherein, in a flow canal for the fluid, there is provided at least one baffle chamber, the volume of which is greater than the maximum volume of fluid and is so shaped that the fluid, in the case of a rotation of the element with a sufficiently high first speed of rotation, remains in it and an outlet canal is connected to the baffle chamber which canal is so con- structed and arranged that at least a part thereof lies closer to the axis of rotation than the fluid surface during the rotation with the first speed of rotation, the walls of which consist of a material wettable by the fluid and the cross-section of which is so constructed that the fluid, in the case of a second speed of rotation, which is smaller than the first speed of rotation, is forced by boundary surface force into the outlet canal; a process is also provided for the control and mixing of a current of fluid subjected to centrifugal force in an element rotating about an axis in the above device, wherein the fluid is driven with a speed of rotation which results in a centrifugal acceleration, which is greater than the gravitational acceleration, into the baffle chamber and, after the expiry of the desired period of residence in the -2- baffle chamber, the speed of rotation is reduced to such an extent that the fluid, driven by boundary sur- face force, fills the outlet canal connected with the baffle chamber, the device and process are particularly useful in chemical and clinical analysis of fluids, for example, body fluids in clinical investigations.
