Abstract: The present invention relates to a container for centrifugation which is mounted in a centrifuge, and more specifically, to a container for centrifugation in which when centrifugation is performed by means of a difference in the specific gravity of respective components by applying a centrifugal force to a biological complex fluid such as blood or bone marrow, a valve body for defining a boundary layer between deposited materials and suspended materials which have been centrifugally separated is configured to be capable of reciprocation but prevented from rotation, and a path through which the suspended materials separated from the deposited materials move is widely secured, thereby rapidly separating and recovering a desired component layer. Provided is a container for centrifugation comprising: a main body 100 including a first chamber 110 in which a material to be centrifuged is received, a second chamber 120 in which a suspended material centrifuged from the material in the first chamber 110 is decanted from the first chamber 110 and received and which is positioned on one side of the first chamber 110, and a coupling part 130 formed to surround the first chamber 110 and the outside of the upper end of the second chamber 120; and a cover 200 which covers an upper portion of the main body 100 and forms a fluid communication path P of the decanted suspended material between the first chamber 110 and the second chamber 120, wherein the inside of the first chamber 110 has valve bodies 140, 140', 140", and 140'" which are disposed to linearly reciprocate in a longitudinal direction of the first chamber 110 to be positioned on a boundary layer between the centrifuged materials and have through-holes 145, 145', 145", and 145'" formed on the bottom surface and through which the material to be centrifuged is separately moved, the cover 200 is configured by a ring part 230 which forms the rim of the cover 200 and is formed to be coupled to the coupling part 130 at the rim of the cover, a recess part 220 which is connected to the inner side of the ring part 230 to be formed in a recessed shape, and a protrusion part 210 which is connected to the inner side of the recess part 220 and formed in a protruding shape to form a fluid communication path P so that the suspended material is discharged from the first chamber 110 to the second chamber 120, in the protrusion part 210, an inlet port 212 is formed to protrude from the protrusion part 210 for injecting the material to be centrifuged to the first chamber 110, the recess part 220 has an air vent for discharging inner air by injecting the material to be centrifuged to the first chamber 110 and a discharge port for discharging a suspended material introduced into the second chamber 120, the ring part 230 includes an outer ring part 231, a planar ring part 232 connected to the outer ring part 231, and an inner ring part 233 which is connected with the planar ring part 232 and has a stepped portion, wherein a ring hook 231-1 is formed on an inner peripheral surface of the outer ring part 231, and an outer end portion of the coupling part 130 has a coupling hook 131 which is extended upward and corresponds to an outer peripheral surface so as to be coupled with the ring hook 231-1 of the inner ring part 231.
