ABSTRACT:
A blood collection tube is provided with a blood phase partitioning device disposed in the upper portion or adjacent the low density blood phase end of the tube. The device carries blood phase barrier gel-like material which flows through a restricted orifice in the device to meter or reduce the flow rate of the material into the blood during centrifugation to suitably delay the formation of the complete phase barrier until complete blood phase separation has taken place.
