ABSTRACT:
This invention is an apparatus for the separation of liquid such as serum or plasma from centrifugated solid particles such as red cells, and for the separation of the liquid into containers for use in an auto-analyzer, and/or storage as well as preservation and distribution of the remainder of the separated liquid samples into other containers.
A single component device is utilized for the separation and distribution of the upper layer of the liquid prepared by centrifugal motion. The apparatus comprises a flexible tubing, a stopper and a capillary tube passing through the system. There is provided the means for the storage of the remainder of liquid, after the adequate amount of samples are obtained and placed in containers for use in an auto-analyzer, and for the easy distribution or transfer of the liquid in the main tube, into other tubes or containers without the need of other apparatus. Several embodiments are illustrated.
