FLUID CONTROL DEVICE WITH MULTI-CHANNEL FOR SIMULTANEOUSLY PERFORMING PROCESSES SUCH AS EXTRACTING, SEPARATING, REFINING AND ENRICHING

PURPOSE: A fluid control device with a multi-channel is provided to simultaneously control fluid in plural fineness channels by transporting various kinds of fluid in a substrate having polymer material. CONSTITUTION: A fluid control device with a multi-channel includes a substrate tray(10), a plurality of rollers(21), a roller slider, a slider shaft, a stepping motor, and a pressure motor(30). The substrate tray(10) fixes a polymer substrate having at least two fineness channels. A plurality of rollers(21) move in a longitudinal direction and pressure the substrate according to each fineness channel of the polymer substrate mounted on the substrate tray(10). The roller slider fixes the rollers such that the rollers can be rotatably transported. The slider shaft guides a transportation direction. The stepping motor rotates the slider shaft so as to provide transportation force to the slider shaft. The pressure motor(30) give a pressure to the roller.
