A centrifuge syringe for separating components of a fluid sample having different sedimentation densities is disclosed. The centrifuge syringe allows for the withdrawal of a sample through a sterile needle into the syringe. The syringe contains a movable plunger containing a restriction and which may contain a density gradient separation solution. The plunger is connected to a handle which is detachable to allow centrifugation. After centrifugation, the handle is reattached to the plunger, and the specimen is removed from the syringe.
