LIQUID HANDLING DEVICE, LIQUID HANDLING METHOD, AND LIQUID HANDLING SYSTEM

摘要

This liquid handling device has a first flow passage and a second flow passage. The first flow passage is a flow passage through which first droplets containing a plurality of objects to be sorted can move, and includes a first branching portion. The second flow passage has a droplet dividing portion and a second branching portion. The droplet dividing portion is disposed on the downstream side of the first branching portion, and divides the first droplets containing a prescribed object to be sorted, to generate second droplets containing at most one object to be sorted. The second flow passage is a flow passage through which the second droplets can move. The second droplets can be sorted in the second branching portion. The cross-sectional area of the first flow passage is greater than the cross-sectional area of the second flow passage at an exit of the droplet dividing portion.
