CENTRIFUGAL SEPARATION CONTAINER, CENTRIFUGAL SEPARATION DEVICE, AND CENTRIFUGAL SEPARATION METHOD USING SAID CONTAINER AND DEVICE

摘要

A storage portion forming a storage space 10, includes an inclined inner wall portion 20 that is connected to a base portion so that the diameter of the inclined inner wall portion gradually decreases; a concave portion 22 is formed at a part of the inclined inner wall portion; and the concave portion 22 includes a concave portion side surface 22b that is connected to a concave portion bottom surface 22a. The concave portion 22 is formed at a position, where the concave portion crosses an interface S between the specimen centrifuged during rotation and air, in a radial direction with respect to the central axis; and the maximum width of the concave portion 22 in a circumferential direction around the central axis is included in a range of 2 mm to a length of 20% of the whole circumference.

1. A centrifugal separation container that is used in a method of centrifugally separating a first specific gravity component and a second specific gravity component, of which a specific gravity of the second gravity component is higher than a specific gravity of the first specific gravity component, contained in a specimen injected into a storage space by rotating a container about a central axis of the container as a rotation axis, the centrifugal separation container comprising:
a storage portion that forms the storage space, wherein the storage portion includes an inclined inner wall portion of which a diameter gradually decreases from an upper end toward a lower end thereof and the lower end is connected to a base portion, a concave portion is formed at a part of the inclined inner wall portion, the concave portion includes a concave portion side surface that is connected to a concave portion bottom surface with a width of the concave portion gradually decreases toward the concave portion bottom surface from the inclined inner wall portion, the concave portion is formed at a position, where the concave portion crosses an interface between the specimen centrifuged during rotation and air, in a radial direction with respect to the central axis, and the maximum width of the concave portion in a circumferential direction around the central axis is included in a range of 2 mm to a length of 20% of the whole circumference passing through the concave portion having a center on the central axis.
