Microparticle sorting apparatus, microchip and microchip module

摘要

Disclosed herein is a microchip including a substrate and a sample flow path within the substrate. The sample flow path includes a changing flow path and a microtube connected to the changing flow path. The changing flow path is configured to change a cross sectional shape of the sample flow path from a quadrangular shape at a first end to a circular shape at a second end. The microtube is connected to the second end of the changing flow path and is disposed within the substrate.
