The present invention relates to a centrifuge tube for use in the centrifugation of biological materials, wherein the diameter of the centrifuge tube is improved to enable minute centrifugation, and in which a thin, weak, and narrow portion of the centrifuge tube, to which a strong force is to be applied, is provided with a support piece to enable centrifugation to be performed without causing a deformation in the centrifuge tube. The centrifuge tube of the present invention enables the centrifugation of materials using differences in the specific gravities of the materials to be easily performed without using a reagent or the like. The centrifuge tube of the present invention has a closure made of a material such as a rubber, polyethylene, polypropylene, silicon or the like, such that a needle may penetrate through the closure and the centrifuge tube can be protected from contamination caused by bacteria, and centrifugation of biological materials can be performed in a closed space. |
