DEVICE FOR INJECTING VARIOUS REACTANTS SUCCESSIVELY AND SYNCHRONOUSLY IN PARALLEL

摘要

PROBLEM TO BE SOLVED: To provide a minute circulation device which can excellently be controlled synchronously in parallel. SOLUTION: This minute circulation device for injecting a series of movable reaction chambers (102, 103) and immiscible segmented beads (101) into micro- channels (21-26) synchronously in parallel is provided with an injecting means (10) for injecting a liquid for the chambers (102, 103) and another liquid for the beads (101) alternately in parallel and a first controlling means for controlling the propagation of one of the liquids in one channel. The first controlling means can stop the propagation of one of the liquids in a region (31) by making good use of the action of one of the liquids according to the physical and chemical characteristics.
