Abstract
A dispersed phase (O) supplied inside a bulkhead member (17) through a supply port (14) enters a gap (20) between a plate (16) and a base (18) through a supply port (19) of the base (18) and the dispersed phase (O) having entered the gap (20) then enters a continuous phase (W) through a boundary section (21) by virtue of pressure applied by a pressurizing means such as a pump. Then, the dispersed phase is made into a particle having a predetermined diameter by a microchannel (24) in passing through this boundary section (21), thereby forming an emulsion (E) in which the dispersed phase (O) of the predetermined diameter is dispersed in the continuous phase (W).
Claims4
A device for producing emulsions of a dispersed phase in a continuous phase comprising:
- a plate;
- a base having a supply port for the dispersed phase and with a protruded bar, said protruded bar contacting said plate to form a gap to which said dispersed phase is supplied through said supply port, said protruded bar forming a boundary section between the dispersed phase and the continuous phase, said protruded bar having a plurality of protrusions forming microchannels in intervals between protrusions;
- wherein the dispersed phase is brought into contact with the continuous phase via the micorchannels.
