CPC classification number: G01N1/34 , G01N35/1009
Abstract: A sample purification apparatus includes a container for separating a mixed sample based on a specific gravity difference with the use of a heavy solution, a heavy solution introduction portion for introduction of the heavy solution into the container, a flow-out portion provided vertically above the heavy solution introduction portion in the container, the flow-out portion arranged so that a supernatant of a solution in the container due to the introduction of the heavy solution is flowed out to the outside of the container, and a collector provided vertically below the discharge portion in the container, the collector collecting a component in the mixed sample, the component being lighter in specific gravity than the heavy solution from the supernatant flowed out from the flow-out portion.

Abstract: A sample purification apparatus includes a container for separating, with a heavy solution, a mixed sample based on a specific gravity difference 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. The container includes a flow-out port provided in an uppermost portion of the container and a flow-out path that guides the supernatant flowed out through the flow-out port to the collector. the container has a horizontal cross-sectional area which gradually decreases upward starting from a prescribed height of the container to a height where the flow-out port is located.
