ABSTRACT:
An arrangement of separation device is provided such that after centrifugation, for example, the heavy materials at the bottom of the separation container may be directly removed from the bottom without first having to decant or otherwise remove the lighter fraction at the upper end of the container. The arrangement may include, for example, a conventional tube-type container modified to have an opening in the bottom. A specially configured plug or stopper is utilized in combination with the container bottom opening to seal the opening closed, which plug is configured to complete the bottom end of the container and to provide an access septum for needle penetration in the bottom of the container. The arrangement of the plug prevents displacement thereof, once it is properly positioned, and includes specifically, a locking detent to prevent the plug from being displaced inwardly upon insertion of a needle into the plug.
