LIQUID SUPPLY METHOD, CENTRIFUGAL SEPARATION METHOD, LIQUID SUPPLY DEVICE AND CENTRIFUGAL SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/042177
Kind Code:
A1
Abstract:
Provided is a liquid feed method and the like which use a centrifugal method, and which can stabilize the laminar flow within micropassages provided to microdevices and the like. By layering two or more different liquids having different densities in order from the liquid having smaller densities, moving towards the outside in the radial direction of the centrifugal rotor, within micropassages positioned in the direction of rotation of the centrifugal rotor, the density gradient within the micropassages is varied into a stepped form. A density gradient is formed within the micropassages, and by matching the direction of gradient of the density and the the direction in which the centrifugal force acts, a secondary flow generated by a Coriolis force is suppressed using the centrifugal force that acts on the liquid, making it possible to stabilize the laminar flow.
