Apparatus for collection, separation and isolation of blood

摘要

Disclosure is made of a novel apparatus for the collection, separation and isolation of serum or plasma from blood obtained from mammalian capillary sources. The apparatus comprises a tubular blood collection component and an airtight closure therefor. The closure member includes a reservior and means of dispensing a thixotrope into the blood collection chamber, under centrifugal force, to effect a physical separation and isolation of the desired serum or plasma. The apparatus is advantageously employed to minimize loss of blood gases during separation and holding.
