ABSTRACT:
A fluid collection device is provided which includes a container for receiving a liquid, such as blood, which is centrifugally separable into relatively light and heavy phases, and a phase partitioning device in the container. The partitioning device includes a bag filled with a thixotropic gel-like sealant having a specific gravity between the specific gravities of the separated light and heavy phases. During centrifugation, the components of the cellular phase cause collapse of the bag and the flow of sealant through an outlet in the bag. The sealant flows to the interface between the two phases during centrifugation and provides a barrier between the separated phases.
