PROBLEM TO BE SOLVED: To provide a separation container set which has a double structure comprising an outer container and an inner container and achieves both reduction of the residual liquid amount and suppression of overflow.SOLUTION: A separation container is for separating a separation object from a liquid sample and includes a cylindrical inner container whose upper and lower ends are opened, and a bottom-closed cylindrical outer container whose upper end is opened and whose lower end is closed. The inner container can be inserted into the outer container. The separation container has a clearance between the outer and inner containers from the lower end of the inner container to the upper end of the outer container in a state of inserting the inner container into the outer container. The clearance comprises a capillary region which is formed in a direction from the lower end to the upper end, and a liquid reservoir region which is formed on the capillary region by being connected to the capillary region. Both reduction of the residual amount and suppression of overflow can be achieved by the clearance.COPYRIGHT: (C)2014,JPO&INPIT【課題】残液量の低減と、オーバーフローの抑制の両方を実現する、外容器と内容器とを備える二重構造の分離容器セットを提供する。【解決手段】本発明の分離容器は、液体試料から分離対象物を分離するための分離容器であって、上端と下端が開口した筒状の内容器と、上端が開口し下端が閉口した有底筒状の外容器を含む。内容器は、外容器の内部に挿入可能である。そして、分離容器は、外容器に内容器を挿入した状態で、内容器の下端から外容器の上端にわたって、両者の間に間隙を有し、前記間隙は、その下端から上端方向に向かって形成された毛管領域と、前記毛管領域の上方向に前記毛管領域と連結して形成された液だめ領域とを含む。前記間隙によって、残存量の低減とオーバーフローの抑制の両方が実現できる。【選択図】図3
