TWO-PHASE FLOW STABILIZING CHIP

摘要

PROBLEM TO BE SOLVED: To stabilize a two-phase flow formed in the flow channel in a microchip. SOLUTION: Grooves different in cross-sectional area are respectively formed to the surfaces of two substrates and the groove forming surfaces of both substrates are laminated to form a flow channel having a protruded cross section, which comprises flow channel parts different in cross-sectional area, in the chip. When two kinds of solvents different in properties are allowed to flow to the flow channel from an introducing port. The interface of the two-phase flow is rotated by 90°to become parallel to the bonded surface of the chip and the two-phase flow is stabilized. COPYRIGHT: (C)2006,JPO&NCIPI
