Centrifuge syringe

A centrifuge syringe (1) comprising a syringe barrel (2) and a syringe plunger (3) axially displaceable in the syringe barrel (2), whereby a receiving volume (4) enclosed by the syringe barrel (2) and the syringe plunger (3) is formed for a body fluid, preferably blood (5),

• wherein the syringe barrel (2) comprises a receiving opening (12) for taking up the body fluid into the receiving volume (4),
• characterized in that
• the syringe plunger (3) has a plunger sealing section (8) and a plunger rod (9) undetachably formed on the plunger sealing section (8), wherein the syringe plunger (3) has a passage (15) extending axially through the plunger sealing section (8) and the plunger rod (9) for a fluid connection between the receiving volume (4) and a removal opening (16) at the end of the plunger rod (9) which faces away from the receiving volume (4), and
• wherein the syringe plunger (3) is of such a length that, if the syringe plunger (3) is in a position in the syringe barrel (2) with a minimum receiving volume (4), the removal opening (16) is arranged essentially at an end of the syringe barrel (2) opposite the receiving volume (4) or protrudes from the syringe barrel (2),
• the centrifuge syringe (1) being designed such that a body fluid, preferably plasma (6) after centrifugation, can be transferred from the receiving volume (4) into a withdrawal container connected to the removal opening (16) by reducing the receiving volume (4).
