1. A sample purification apparatus that purifies a mixed sample, the sample purification apparatus comprising:
a container for separating, with a heavy solution, the mixed sample based on a specific gravity difference, the container having a central axis direction; and
a collector that collects a component in the mixed sample lighter in specific gravity than the heavy solution by receiving a supernatant flowed out from the container,
wherein
the container includes
a flow-out port provided at an uppermost end of the container in the central axis direction, wherein the flow-out port is located on the central axis, and
a flow-out path that guides the supernatant flowed out through the flow-out port to the collector, and
the container has a horizontal cross-sectional area which decreases upward starting from a prescribed height of the container to a height where the flow-out port is located.
