Abstract: The present invention relates to a container for centrifugation which is mounted in a centrifuge. More specifically, the present invention relates to a container for centrifugation which, when applying a centrifugal force to a biological complex fluid such as blood or bone marrow and performing centrifugation by means of a difference in the specific gravity of respective components, configures a valve body, for defining a boundary layer between deposited materials and suspended materials which have been centrifugally separated, to be capable of reciprocation but prevented from rotation, and which widely secures a path through which the suspended materials separated from the deposited materials move, thereby rapidly separating and recovering a desired component layer. The container for centrifugation comprises: a main body (100); and a cover (200). The main body (100) comprises: a first chamber (110) in which a material to be centrifugally separated is received; a second chamber (120) which is positioned on one side of the first chamber (110), and in which suspended materials, centrifugally separated from the material in the first chamber (110), are received after being decanted from the first chamber (110); and a coupling part (130) which is configured to surround the outer sides of the upper ends of the first chamber (110) and the second chamber (120). The cover (200) covers the top of the main body (100) and has, between the first chamber (110) and the second chamber (120), a fluid communication path (P) for the decanted suspended material. The first chamber (110) comprises therein valve bodies (140, 140', 140", 140"') which are disposed to be able to linearly reciprocate along the longitudinal direction of the first chamber (110) so as to be positioned at a boundary layer between materials to be centrifugally separated, and which have, on the bottom surfaces thereof, through-holes (145, 145', 145", 145"') through which the material to be centrifugally separated is separated and moves. The cover (200) comprises: a ring part (230) which forms the rim of the cover (200) and is configured to be coupled to the coupling part (130) at the rim of the cover (200); a recess part (220) which is configured to be recessed and is connected to the inside of the ring part (230); and a protrusion part (210) which is configured to protrude and is connected to the inside of the recess part (220) so as to form the fluid communication path (P) such that the suspended material is discharged from the first chamber (110) to the second chamber (120). The protrusion part (210) has an inlet port (212), which protrudes therefrom, for injecting the material to be centrifugally separated into the first chamber (110). The recess part (220) comprises: an air vent for discharging inside air as the material to be centrifugally separated is injected into the first chamber (110); and a discharge port for discharging the suspended material introduced into the second chamber (120). The ring part (230) consists of: 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 to the planar ring part (232) and has a stepped portion. The outer ring part (231) has a ring hook (231-1) formed on the inner circumferential surface thereof. The outer end of the coupling part (130) extends upward and forms a coupling hook (131) having a shape corresponding to the outer circumferential surface so as to be coupled to the ring hook (231-1) of the inner ring part (231).
