PROBLEM TO BE SOLVED: To prevent a component extracted by centrifugation from remaining stuck in a storage part without cost increase in a container for centrifugation for centrifuging the components of a specimen in the container by rotation with the central axis of the container as a rotational axis.SOLUTION: A container 1 for centrifugation includes a storage part 11 for storing a specimen within a container body 10 having a substantially columnar shape in appearance. In the top surface of the container body 10, there is provided an opening 12 for injecting the specimen into the storage part 11. In the container 1 for centrifugation, at inner surface positions in the storage part across a boundary surface between a specimen 32 present on the outer peripheral side of the container and air present on the central axis side thereof during the rotation of the container, there are formed three-dimensional structures (grooves 20) each including a corner part which are extended from a central axis C toward an outer periphery.COPYRIGHT: (C)2016,JPO&INPIT【課題】容器の中心軸を回転軸として回転させられることにより容器内の検体の成分を遠心分離するための遠心分離用容器において、コスト増加を招くことなく、遠心分離により抽出した成分が貯留部内で張り付いたままにならないようにする。【解決手段】外観が略円柱形状の容器本体10内部に検体を貯留する貯留部11を備えるとともに、容器本体10の上面に検体を貯留部11内に注入するための開口12が設けられた遠心分離用容器1において、容器の回転時に容器の外周側に存在する検体32と中心軸側の空気との境界面を跨ぐ貯留部の内面位置に、中心軸Cから外周方向に延伸する角部を含む立体構造(溝20)を形成する。【選択図】図8
