MICRO-FLUID DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a micro-fluid device constituted so as not only to markedly enhance the efficiency of the mutual mixing or reaction of different liquids but also to achieve miniaturization. SOLUTION: The micro-fluid device 100 is equipped with a micro-fluid element 10 constituted so as to perform the mixing or chemical reaction of different kinds of liquids supplied from at least two liquid supply ports 15a and 15n in a fine flow channel 28 to discharge the mixture or chemical reaction product of the liquids from the liquid discharge port 18 provided on the downstream side, a liquid feed system for feeding the different kinds of the liquids to the respective liquid supply ports 15a and 15n of the micro-fluid element 10 and a drain system for taking out the liquid discharged from the liquid discharge port 18 of the micro-fluid element 10. This micro-fluid device 100 is provided with an ultrasonic oscillation element 41 constituted so that a fine flow channel 28 is formed by almost parallel opposed wall surfaces 11a and 12a and the liquids flowing through the gap between the almost parallel opposed wall surfaces 11a and 12a are irradiated with ultrasonic waves reflected by the almost parallel opposed wall surfaces 11a and 12a to form a specific flow Fs crossing a liquid flow direction.
