Automatic Vacuum Blood Collection Tube Assembly line


Automatic Vacuum Blood Collection Tube Assembly line

Our new complete solution AUTO RI-BCT- can be used to manufacture and package both vacuum and non-vacuum blood collection tubes,” says Sales Director Chintak Patel. The machine can therefore dispense all common additives, such as gel, EDTA.K2, EDTA.K3, lithium herapin, trisodium citrate, and many more. The system stands out with its modular design and can be extended with further stations if necessary. It covers every required process step all the way to packaging, in polystyrene trays, for example.

Brief Overview:


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. Tubes are available with a safety-engineered stopper, with a variety of labeling options and draw volumes. The color of the top indicates the additives in the vial

A range of Vacutainer tubes containing blood


The Vacutainer needle is double-ended: the inner end is encased in a thin rubber coating that prevents blood from leaking out if the Vacutainer tubes are changed during a multi-draw, and the outer end which is inserted into the vein. When the needle is screwed into the translucent plastic needle holder, the coated end is inside the holder.

When a tube is inserted into the holder, its rubber cap is punctured by this inner needle and the vacuum in the tube pulls blood through the needle and into the tube. The filled tube is then removed and another can be inserted and filled the same way. The amount of air evacuated from the tube predetermines how much blood will fill the tube before blood stops flowing.

Each tube is topped with a color-coded plastic or rubber cap. Tubes often include additives that mix with the blood when collected, and the color of each tube's plastic cap indicates which additives it contains.

Blood collection tubes expire because over time the vacuum is lost and blood will not be drawn into the tube when the needle punctures the cap

Types of tubes

Vacutainer tubes may contain additional substances that preserve blood for processing in a medical laboratory. Using the wrong tube may make the blood sample unusable for the intended purpose. These additives are typically thin film coatings applied using an  nozzle.

The additives may include anticoagulants (EDTA, sodium citrate, heparin) or a gel with density between those of blood cells and blood plasma. Additionally, some tubes contain additives that preserve certain components of or substances within the blood, such as glucose. When a tube is centrifuged, the materials within are separated by density, with the blood cells sinking to the bottom and the plasma or serum accumulating at the top. Tubes containing gel can be easily handled and transported after centrifugation without the blood cells and serum mixing.

The meanings of the various colors are standardized across manufacturers

The term order of draw refers to the sequence in which tubes should be filled. The needle which pierces the tubes can carry additives from one tube into the next, so the sequence is standardized so that any cross-contamination of additives will not affect laboratory results

Vacutainer technology was developed in 1947 by Joseph Kleiner, and is currently marketed by Becton Dickinson (B-D).The Vacutainer was preceded by other vacuum-based phlebotomy technology such as the Keidel vacuum.

The plastic tube version, known as Vacutainer PLUS, was developed at B-D in the early 1990s by E. Vogler, D. Montgomery and G. Harper amongst others of the Surface Science Group as US patents 5344611, 5326535, 5320812, 5257633 and 5246666

Vacutainers are widely used in phlebotomy in developed countries due to safety and ease of use. Vacutainers have the advantage of being prepared with additives, allowing easy multi-tube draws, and having a lower chance of hemolysis. In developing countries, it is still common to draw blood using a syringe or syringes.

Blood collection tubes are among the basic medical supplies taken by disaster relief programs to affected areas


Fully automatic vacuum blood collection tube turnkey project:

Collection in transport systems

  • No Additive Tube – This tube is used for collecting blood and storing it for biochemistry, serology and other tests. It provides non-contaminated serum samples for clinical tests, keeping the serum stable for an extended period of time.
  • Serum blood collection tube – This tube aims at giving high-quality serum sample for medical technologies. It has 3 kinds of tubes: no additive tube with & without clot activator and brick red cap.
  • Hemo Repellent Coated tube – blood collection and storage for biochemistry tests, silicon are used. It is appropriate for a broad range of operation, quick in coagulation. These blood cells don not stick to the side of the tube.
  • Gel + BCA – such tubes are used for clinical and biochemical immunology. There’s a barrier gel present inside the tube at the bottom. After the centrifugation, the gel can easily separate the serum from the cells without causing additives exchange between blood cells and serum.
  • Whole blood collection tube – this tube provides good quality of blood sample for the laboratories. It has 2 kinds of tube (ETDA) (ETDA.K2/K3 and ESR tube.
  • ETDA tube is used for haematology and also as various kinds of blood cell test instruments.
  • ESR tube is used for blood collecting and anticoagulation rate test.
  • Plasma blood collection tube – plasma blood collection tubes give a high quality plasma sample for medical laboratories.
