  • Method and apparatus for separating blood fractions
    Patent number: 3932277
    Abstract: Method and apparatus for filtering and permanently separating the serum fraction from the cell fraction of centrifuged blood and the like. A separator head is passed through the serum and is positioned at the interface of the serum and the heavier red cells. As the separator head is positioned serum passes through a self-sealing passage in the separator head and into a collection tube that positions the separator head. Upon withdrawal of the collection tube the passage in the separator head closes sufficiently to effectively block the passage and the serum can be poured from the collection tube. The collection tube can be reinserted to pour off measured volumes of the serum.
