Tube holder for centrifuge rotor

摘要

A test tube holder for insertion into a cylindrical test tube cavity in a centrifuge rotor to support a plurality of relatively small test tubes within the rotor cavity. The holder includes a body whose shape is substantially that of a cylinder or a longitudinal section thereof. The body has a plurality of small cavities for holding test tubes, the smaller cavities being spaced apart in a direction along the longitudinal dimension of the body. Each of the smaller cavities is arranged at an angle relative to the longitudinal dimension of the body, and each has a mouth opening onto an exterior surface of the body. The test tube holder further includes means for orienting the holder in the centrifuge rotor test tube cavity so that the mouths of the smaller cavities face the rotational axis of the centrifuge rotor when the test tube holder is inserted into said centrifuge rotor test tube cavity.
