Integral one piece centrifuge tube

摘要

A substantially enclosed centrifuge tube having a small fill or access port at one end. In its preferred form there is integrally formed adjacent the fill port a neck or stem which is fused to hermetically seal the centrifuge tube to provide a permanent and complete seal of the centrifuge tube. A plug is securely mounted within the centrifuge rotor above the centrifuge tube when placed in the rotor to provide solid support adjacent the complete exterior surface of the tube. The interior of the plug is shaped to conform and mate with the upper end of the centrifuge tube. The use of a removable capping means placed on the centrifuge tube is eliminated. Access to the tube subsequent to the centrifugation run requires puncturing or cutting of the tube.
