Title:
METHOD AND DEVICE FOR GENERATING EMULSION IN MICRO-CHANNEL CHIP
Document Type and Number:
Japanese Patent JP2022175985
Kind Code:
A
Abstract:
To provide an improved method and device for generating an emulsion, the method for separately supplying a continuous phase liquid and a dispersed phase liquid to a micro-channel chip.SOLUTION: In a micro-channel chip 10, dispersed phase liquid holding units 102, 103 are connected with an emulsion forming unit 120 through a dispersed phase liquid channel 117; a continuous phase liquid holding unit 101 is connected with the emulsion forming unit 120; the emulsion forming unit 120 is connected with an exhaust port 150 through an emulsion channel 130. A method includes, with an external liquid sending driving force, in the emulsion forming unit 120, generating an emulsion including droplets formed of the dispersed phase liquid and a continuous phase formed of the continuous phase liquid, and causing the emulsion to enter the emulsion channel 130. A surface of a wall surface of a dispersed phase liquid channel 117 is formed of an inorganic material and/or an organic material not containing a fluorine compound and not treated with a fluorine compound.SELECTED DRAWING: Figure 1
