PROBLEM TO BE SOLVED: To provide a bucket for centrifugal separators for a low speed operation in which a permissible rotation speed can be raised.SOLUTION: The bucket for centrifugal separators is formed by bending a metal plate, and includes a plate holder and an attaching unit. The plate holder holds a plate that has a plurality of sample holes for putting samples therein, and an outer peripheral wall extending to a position which is lower by a predetermined length than the bottom surface of the sample holes in the outer peripheral part. The attaching unit is installed to a swing rotor of the centrifugal separator so as to rotate at an angle corresponding to a centrifugal force. The plate holder has a bottom plate having a sample region opposing to the bottom surface of the sample holes, and an outer peripheral wall region opposing to the outer peripheral wall. Projecting portions preventing the bottom plate from curving are formed only in a part of the sample region in the bottom plate. Moreover, the projecting portion is extruded to the direction of the bottom surface of the sample hole so as to have a height of a predetermined length or more. |
