Abstract
A fluid collection apparatus is disclosed which is useful in separating blood serum or plasma from blood cellular and particulate matter. The apparatus comprises an elongated hollow body closeable at both ends with a self sealing septum near one end. The septum includes a central cavity extending axially from one end of the septum and terminates in a web portion. The septal web portion is pierced by a composite piston member which includes a passageway equipped with a filter. Fluid, therefore, flows through the filter, the piercing means and into the hollow body. A flange on the composite piston extends laterally of the hollow body and sealingly engages the inner wall of a tube filled with a sample of mixed materials. Upon withdrawal of the apparatus, the composite piston remains sealed in the sample containing tube. The web portion of the hollow body reseals on withdrawal of the piercing means to prevent leakage. The uncontaminated, self-sealed, hollow body-septum portion of the apparatus may be capped for shipment.
