Abstract
A blood collection device is provided with a phase partitioning device which includes a standpipe connected to a reservoir filled with a sealant material having a specific gravity intermediate the specific gravities of separated light and heavy phases of blood. Components of the heavy phase of blood enter the reservoir during phase separation and centrifugation to force sealant upwardly in the standpipe and out into the tube above the line of separation.
