Abstract
A chamber chipis provided with a pre-branching chamber, branching chamber, and a guiding fluid passagefor these chambers. The branching chamberhas a separation wallwhich defines two branching compartmentsA andB. A wall surface of the branching chamber positioned at a side of the rotary shafthas a spread angle θe from an outlet end sectionof the guiding fluid passagewhich is an obtuse angle. The rotation of the chamber chipabout the rotary shaftcauses a liquidto flow from the pre-branching chamberthrough the guiding fluid passageinto the branching chamber. By a Coriolis force acting in an opposite direction to a rotation direction R, Rabout the rotary shaft, the liquidis selectively supplied to any one of the branching compartmentsA andB.
