The present invention provides a method of transferring beads in a fluidic chip comprising an internal fluid circuit through which various reactants, in which at least one of the reactants are beads, may be moved by use of centrifugal force, the method comprises the steps of: providing beads (8) having a density equal to, or lower than, ml in a section (7, 15) of the fluid circuit, the section comprising at least a first outlet (16, 13); providing a first liquid medium to the section, the liquid medium having a density d2, such that d2>ml; and applying a centrifugal force such that the beads migrate in the opposite direction of the centrifugal force. |
