Centrifuge sample container and centrifuge rotor and centrifuge using it

摘要

By realizing a flat sample container whose cross-sectional shape is not a perfect circle, a centrifuge with a larger total number of sample containers that can be mounted on the rotor will be realized. In the sample container 40 for a centrifuge having a tubular body portion 41 and a bottom portion 42 that closes the lower end side of the body portion, the body portion 41 has a cylindrical shape having two parallel planes and is oval when viewed from above. The bottom portion 42 is formed by a semi-cylindrical portion 42a and a quadrilateral spherical portion 42b connected to the side thereof. The height H of the sample container is made larger than the length L2 in the minor axis direction of the opening, and the radius of curvature R1 of the outer surface of the oval arc portion, the radius of curvature R2 of the outer surface of the semicylindrical portion, and the outer surface of the quadrilateral spherical portion The radius of curvature R3 is the same curvature. Further, a flange portion 43 extending radially outward is formed in the opening 44 portion of the body portion 41.
