VERFAHREN UND VORRICHTUNG ZUM TRENNEN UND ISOLIEREN VON BLUT- ODER KNOCHENMARKSKOMONENTEN.

摘要

Centrifugal apparatus for separating components of a biological mixture such as blood, comprising a plurality of co-rotating containers spaced from and distributed evenly about the centrifugal axis, a first co-rotating liquid system for containing the biological mixture, said first liquid system comprising a primary source reservoir in each container, at least one primary receiving reservoir connected to said source reservoir through a respective primary conduit, and primary pumping means for letting at least a portion of said biological mixture flow from the primary source reservoir to said primary receiving reservoir during centrifuging, the apparatus further comprising a co-rotating secondary liquid system for compensating the decrease in weight of each of the containers resulting from the outflow of the portion of the biological mixture from the primary source reservoir in order to keep the apparatus in balance during pumping. The density of the secondary liquid is larger than that of the heaviest component of the mixture which is to be separated.
