Title:
CENTRIFUGE SAMPLE CONTAINER, CENTRIFUGE ROTOR USING SAME, AND CENTRIFUGE
Document Type and Number:
WIPO Patent Application WO/2019/106933
Kind Code:
A1
Abstract:
Provided is a centrifuge in which the total number of sample containers that can be loaded into a rotor is increased compared to the prior art by utilizing a flat sample container which does not have a perfectly circular cross-section shape. In a centrifuge sample container 40 having a cylindrical body part 41 and a bottom part 42 that closes the bottom end side of the body part, the body part 41 has a cylindrical shape having two parallel flat surfaces, and includes an opening 44 having an elliptical shape when viewed from above. The bottom part 42 is formed by a semi-cylindrical part 42a and semi-hemispherical parts 42b connected to the sides of the semi-cylindrical part. A height H of the sample container is greater than a length L2 in the short axis direction of the opening, and a curvature radius R1 of the outer surface of an arc part of the elliptical shape, a curvature radius R2 of the outer surface of the semi-cylindrical part, and a curvature radius R3 of the outer surface of the semi-hemispherical parts are equal. A flange part 43 that expands toward the outside in the radial direction is formed on the opening 44 portion of the body part 41.
