Process and device for the control and mixing of a fluid current subjected to centrifugal force |
摘要 |
A process and a device for the centrifugal control and mixing of a limited volumes of fluid, especially in the rotor of a centrifugal analyzer, has at least one baffle chamber, in a flow canal for the fluid the volume of which is greater than the volume of fluid. It is so shaped that, when the device is rotated at a sufficiently high first speed of rotation, the fluid remains in it. An outlet canal is connected to the baffle chamber the fluid. 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 the outlet canal consist of a material which is wettable by the fluid and, in combination therewith, have cross-section which forces the fluid out of the baffle chamber; by boundary surface force when the device is rotated at a second, slower speed.
