Evacuated Blood Tubes
Capped sterile tubes with an internal vacuum that are commonly used to collect venous blood specimens; products are available in various materials, with various stopper types, and anticoagulants.
Evacuated blood tubes are sealed, single-use, capped tubes used with suitable collection needles and tubing for the safe and sterile collection of blood samples from human or animal subjects. They are partially evacuated to facilitate blood draw when the collection needle punctures the cap. The closure caps may be color-coded, depending on the tube additives or specific purpose.
Evacuated blood tubes are typically made of plastics such as polypropylene or PET to minimize the risk of breakage, although glass evacuated blood tubes are also available. Available as plain, empty tubes, many are pre-loaded with additives or preservatives that stabilize the blood sample or contain gel separators to facilitate the separation of blood cells from serum or plasma.
Evacuated blood tubes are widely employed in hospital blood collection (phlebotomy) departments and in other clinical, veterinary, and research settings. Once filled, evacuated blood tubes can be securely stored or transported for subsequent analysis of serum, plasma, or whole blood by clinical chemistry, blood counts, or other tests.
Types of Evacuated Blood Collection Tubes
• Red top: plain tubes without additives; for serum samples
• Purple top: contain EDTA anticoagulant; for clinical hematology procedures
• Green top: contain heparin; for plasma samples
• Gray top: with added fluoride or oxalate; for glucose determinations
• Blue top: with sodium citrate; for coagulation testing
• Other additives and colored closures
Greiner Bio-One Hematology K2 EDTA Evacuated Tubes
For routine immunohematology testing
Greiner Bio-One VACUETTE™ K2EDTA Blood Collection Tubes
VACUETTE™ EDTA Blood Collection tubes are used for determinations in EDTA whole blood for haematology. Available with K2EDTA, K2EDTA Separator and K3EDTA. VACUETTE™ K2EDTA tubes contain dipotassium K2EDTA which blocks the coagulation cascade.
Greiner Bio-One VACUETTE™ K3EDTA Blood Collection Tubes
VACUETTE™ EDTA Blood Collection tubes are used for determinations in EDTA whole blood for haematology. Available with K2EDTA, K2EDTA Separator and K3EDTA. VACUETTE™ K3EDTA tubes contain tri-potassium K3EDTA which blocks the coagulation cascade.
Greiner Bio-One VACUETTE™ CAT Serum Clot Activator Blood Collection Tubes
VACUETTE™ CAT Serum Clot Activator tubes, used for determinations in serum, are coated with micronized silica particles that activate clotting when the tubes are gently inverted.
Greiner Bio-One Blood Collection Tubes
Can be used for CSF determinations
Greiner Bio-One Trace Element Studies Evacuated Tube
Designed for testing of trace elements
Greiner Bio-One K2EDTA GelTubes
For plasma preparation in molecular diagnostics. Greiner Bio-One K2EDTA GelTubes is also used for detection of viruses, parasites and bacteria.
Greiner Bio-One VACUETTE™ CAT Serum Separator Clot Activator Blood Collection Tubes
VACUETTE™ CAT Serum Separator Clot Activator tubes are evacuated blood collection tubes used for serum determinations. They contain clot-activating micronized silica particles and a gel separator that, once centrifuged, forms a stable barrier separating the serum from fibrin and cells.
Greiner Bio-One VACUETTE™ Heparin Blood Collection Tubes
VACUETTE™ Heparin Blood Collection Tubes have a green top and contain spray-dried lithium, sodium or ammonium heparin on the inner walls and are usedin clinical chemistry, immunology and serology. The anticoagulant heparin activates antithrombin, which blocks the clotting cascade and thus produces a whole blood/plasma sample.

For determinations in clinical chemistry and immunochemistry. Greiner Bio-One Plasma Tubes with Lithium Heparin and Gel includes a safety pull cap.
Greiner Bio-One Coagulation Tubes with Sodium Citrate Solution
For routine hemostasis testing
Greiner Bio-One Serum No Additive Tubes
With non-ridged pull caps
Greiner Bio-One Glycolytic Inhibitor Tubes
Suitable for analysis of blood glucose and lactate.
Greiner Bio-One Chemistry Tubes
Blood Collection Tubes are made out of virtually unbreakable PET plastic
