Abstract
A microfluidic device can include an upstream passage, a sample passage, a bifurcating passage, and a combining passage. The upstream passage can be configured to provide a focusing stream. The sample passage can be configured to provide a sample stream. The bifurcating passage can include a specified bifurcating flow resistance. The combining passage can be configured to create a combined stream from the focusing stream and the sample stream, where the focusing stream can direct the sample stream away from the upstream passage and toward the bifurcating passage. A first portion of the combined stream can be discharged through the bifurcating passage. The main discharge can be configured to discharge a second portion of the combined stream. The main discharge can include a main discharge resistance that is selectable to vary the main discharge resistance relative to the bifurcating flow resistance.
