Abstract

In a container for centrifugal separation that includes a container main body including a retention part in which a sample is retained, and in which a component of the sample in the retention part is centrifugally separated by rotating the container main body about its center axis, as a rotation axis, material having thixotropic properties has been applied to an entire bottom surface of the retention part.

First claim

What is claimed is:

1 . A container for centrifugal separation comprising:
a container main body including a retention part in which a sample is retained, wherein a component of the sample in the retention part is centrifugally separated by rotating the container main body about its center axis, as a rotation axis, and wherein material having thixotropic properties has been applied to an entire bottom surface of the retention part.

2 . The container for centrifugal separation, as defined in claim 1 , the container comprising:
a lid unit to be set toward an opening of the retention part of the container main body, wherein the material having thixotropic properties has been applied also to an inner surface of the lid unit facing the retention part.

3 . The container for centrifugal separation, as defined in claim 1 , wherein the material having thixotropic properties has specific gravity in the middle of specific gravities of two components that are centrifugally separated from each other.

4 . The container for centrifugal separation, as defined in claim 1 , wherein the thickness of a coating formed by application of the material having thixotropic properties is greater than or equal to 5 μm and less than or equal to 1000 μm.

5 . The container for centrifugal separation, as defined in claim 1 , wherein the bottom surface of the retention part includes a funnel-shaped inclined surface.

6 . The container for centrifugal separation, as defined in claim 1 , wherein the material having thixotropic properties is gel.

7 . The container for centrifugal separation, as defined in claim 1 , wherein a trap part in which a component having relatively high specific gravity is stored when centrifugal separation has been performed on the sample is provided at an opening edge part of the container main body.

8 . The container for centrifugal separation, as defined in claim 7 , wherein the material having thixotropic properties has been applied to an inner surface of the trap part.

9 . A method for producing the container for centrifugal separation, as defined in claim 1 , wherein the material having thixotropic properties is applied by spin coating.
