Abstract
An automatic system which combines a three-branch sorter with three independently-controlled valves and corresponding collection platforms. The subgroups of droplets are alternatively sorted into three channels followed by being pumped out into PCR tubes on the platforms. Experimentally, this system can realize an accurate collection with a large working range for both pure positive samples and mixed samples with negative ones. This technology effectively dispenses a large number of droplets into small subgroups with quantitative number, which builds the basis for digital droplet microfluidics.
