A syringe device and methods for device for separating liquids of different densities are provided where the syringe device includes a hollow syringe barrel, a perforated plunger seal with a seal hole, and a hollow plunging tube with a closed bottom with at least one tube hole.

Syringe system for fluid separation

A whole blood separator device has a sleeve. The sleeve has a sleeve body. The sleeve body has an enlarged first proximal end portion and an enlarged second distal end portion and an intermediate cylindrical tube portion connecting the first proximal end portion and the second distal end portion. The sleeve body is configured to fit inside a test tube and receive whole blood which can be separated by centrifugation into a plasma layer in the proximal end portion, a buffy coat layer in the intermediate portion and a red blood cell portion in the distal portion. The whole blood separator device wherein at least the proximal end portion has an open end. Preferably, the distal end portion also has an open end.

Whole blood separator device and method of use

Whole blood separator device

A syringe device for separating liquids of different densities is provided with a hollow syringe barrel, a perforated plunger seal with a seal hole, and a hollow plunging tube with a closed bottom with at least one tube hole. The perforated plunger seal has an outer perimeter that resides flush against an interior surface of the hollow syringe barrel. The tube hole is in operational relationship with the seal hole. Optionally, a relief hole is provided on a top portion of the hollow plunging tube to allow a user to create vacuum pressure as necessary.
