Blood centrifuge with exterior mounted, self-balancing collection chambers

[Subject] The thrown-away type centrifuge or separation assembly object which is equipped with the collection chamber which receives and holds the fluid which should carry out [solution means] centrifugal separation and in which this chamber has a perimeter edge, an inner periphery edge, a cross-sectional area circular as a whole, and a conic outside collection portion. A collection chamber is manufactured with the material of the fabricated typical comparatively hard plastic or others. That balance should be made easy for rotation of a smooth centrifuge, in order to attach a thrown-away type centrifuge to the rotor of a centrifuge, an attachment assembly object is included as a part of the present invention. A chamber has the further port that 連通 near the outside portion of the chamber which offers the fluid 連通 state over a pipe, and this port, It is considered as single 管腔, and when it is a form of the discontinuity implementation for which a single pipe is used for filling and extraction, since it is filling, 入口管腔 is used, and since it is extraction of the separated ingredient, when it is a form of implementation of continuous filling and extraction for which one or more 出口管腔 are used, it can be considered as a large number pipe 腔.
