Abstract
The invention provides a method for moving a fluid sample within an open channel flow device by centrifugal force and specially adapted apparatus for practicing the method of the invention. The inventive method is a mechanically simple method for moving a fluid in a platform by changing the orientation of a platform relative to the direction of applied forces when the centrifuge rotor is at rest in order to move a fluid sequentially through a plurality of chambers, wherein movement of the fluid is controlled by the location or size of the passages connecting chambers relative to the direction of forces acting on the fluid.
