PROBLEM TO BE SOLVED: To provide a centrifuge which improves rigidity of a sample container for the centrifuge using a rotor of a swing type and improves a life of the sample container.SOLUTION: A centrifuge swings a sample container 30 in accordance with rotation and performs centrifugal operation while causing the sample container to seat on a notched part of a rotor main body, and the sample container includes a bucket 51 which houses the container into which a sample is taken and a cover part 31 which has a swinging shaft and tightly seals the bucket, and grooves 80 extended in the longitudinal direction are formed on an outer circumferential surface of the bottom surface side rather than a seating surface 54c of the bucket. The grooves 80 are formed by cutting processing of a ball end mill or the like and are provided at a regular interval in the circumferential direction by two or more lines. By introducing the grooves, weight increase of the bucket is suppressed and, at the same time, the sample container having high rigidity which can endure deformation can be provided.SELECTED DRAWING: Figure 4 |
