Abstract:

[PROBLEMS] To control bubble removal or mixing in a flow channel. [MEANS FOR SOLVING PROBLEMS] Bubble transfer between flow channels (1,2) is controlled by a measure including disposing first flow channel (1) for flow of a first fluid of liquid or gas and second flow channel (2) for flow of a second fluid of liquid with, interposed therebetween, gas exchange zone (5) through which while no liquid can pass, a gas component can be transferred, and including providing a pressure difference between the flow channels (1,2) with the gas exchange zone (5) interposed therebetween. By rendering the pressure of the second flow channel (2) higher than that of the first flow channel (1), any Bubble transfer from the first fluid to the second fluid is prevented, or bubbles within the second fluid are transferred into the first fluid to thereby attain deaeration.
