A vacutainer blood collection tube is a sterile glass or plastic test tube with a colored rubber stopper creating a vacuum seal inside of the tube, facilitating the drawing of a predetermined volume of liquid. Vacutainer tubes may contain additives designed to stabilize and preserve the specimen prior to analytical testing.
Most blood collection in the US, UK, Canada and Hong Kong is done with an evacuated tube system. Two common systems are Vacutainer (Becton, Dickinson and company) and Vacuette (Greiner Bio-One). The equipment consists of a plastic adapter, also known as a tube or needle holder/hub, a hypodermic needle and a vacuum tube.
A venipuncture performed using a vacutainer. A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid from the body for analysis. Blood flows throughout the body, acting as a medium that provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disposal ...
A large SST II vacutainer. Serum-separating tubes, also known as serum separator tubes or SSTs, are test tubes used in clinical chemistry tests requiring blood serum.
Phlebotomy is the process of making a puncture in a vein, usually in the arm, with a cannula for the purpose of drawing blood. [1] The procedure itself is known as a venipuncture, which is also used for intravenous therapy.
Butterfly needle. A winged infusion set—also known as "butterfly" or "scalp vein" set—is a device specialized for venipuncture: i.e. for accessing a superficial vein or artery for either intravenous injection or phlebotomy.
The Keidel vacuum tube was a type of blood collecting device, first manufactured by Hynson, Wescott and Dunning in around 1922. [1] This vacuum was one of the first evacuated systems, predating the more well known Vacutainer. [1]
An example of such a product is the "Accuspin System Histopaque-1077" sold by Sigma Aldrich. The cost of this product is significantly higher than basic Ficoll and Ficoll-Paque products. It is also possible to have the Ficoll-Paque separating system included in the Vacutainer used to collect the blood. Such Vacutainers increase the convenience ...
