<p>This invention is directed to a centrifuge tube formed from molded plastic and includes a body shaped as a bellows-folded helix having a closed bottom and a syringe tip at its top. The bottom may be pierced following centrifuging of the contents by a double tipped needle so that the tube may also serve as a positive syringe to expel any desired portion of the collected solids for subsequent examination.</p> |
