Method of mixing two liquids in a converging device comprising a microchannel chip

摘要

A microchannel chip (10), includes: a first channel (16) where a first liquid is transported from one end side to an opposite end side; a port section (14) to which a second liquid is supplied from outside for accumulating the second liquid; and a second channel (18) connecting the first channel and the port section through a first opening provided in a side of the first channel and a second opening provided in the port section, wherein the second channel checks flowing out of the second liquid accumulated in the port section to the first channel by a Laplace pressure valve until the first liquid arrives at the first opening, and the second channel converges the second liquid into the first liquid after the first liquid reaches the first opening, and a converging device using the same.
