Production of quality blood collection tubes

The production of blood sampling tubes in Banyan Danesh Daru Mad Company is done with the best quality and its delivery is free all over Iran.

For the production of blood collection tubes, the best high quality materials must be used and then these materials are formed into a tube and in some cases a protective cap is also used to ensure the quality of the blood collection tubes, Daro Mad Company tests them and the protocol Safety measures are well followed.

Production of blood collection tubes with quality and direct order

The process of producing blood collection tubes is produced according to the needs of laboratories, for example, blood collection tubes with EDTA coating are used for laboratories, and they are also produced with different sizes and shapes.

6ml gel clot tube
8ml tube with gel clot
Tube of 9ml gel clot

In any case, for the production of blood collection tubes, all standards must be followed in order to deliver sanitary blood collection tubes to the laboratories because they are very useful in answering tests.

The tests that are performed on the blood collection tube include:

Pressure test, thermal test, chemical test

What is the structure of blood collection tubes?

As one of the medical products, blood collection tubes are very sensitive and are used to collect the patient’s blood sample and must be made with the highest quality.

The physical structure of the blood collection tube: it must be made of quality and resistant materials so that it has a significant durability.

Gel that accelerates blood coagulation: Gel that accelerates blood coagulation should be used inside blood collection tubes so that the blood does not clot.

Blood collection tube capacity: Blood collection tubes are made in different sizes to collect enough blood samples and perform the necessary tests.

Coloration of blood collection tube lids: The blood collection tube lids have special colors that we will explain below.

Transparency: The inside of the blood collection tubes should be visible.

6- Transparency: Quality blood collection tubes should be very transparent so that you can easily see inside and make sure that the blood sample is completely inside the tube.

Color list of vacuum blood sampling tubes

Purple blood collection tube: the substance in the tube is EDTA and is used to determine the blood group (CBC, G6PD, Retic

Light blue blood collection tube: the substance in the tube is 1 unit of trisodium and 9 units of blood. It is also used for coagulation test.

Light green blood collection tube: the substance in the tube is lithium heparin and it is used in the metabolic test (BMP, CMP).

Royal blue blood collection tube: The substance in the tube contains disodium EDTA or empty and is used to determine nutrients.

Golden blood collection tubes: the material inside the tube is a gel that separates and activates blood coagulation and is used for biochemical and serological tests.

Red blood collection tube: the inside of the tube activates blood coagulation and is used for lipid tests

Dark green blood sampling tube: inside the tube contains sodium heparin and is used for blood gases.

Gray blood collection tube: Contains sodium fluoride inside the tube and is used for blood sugar testing

Black blood collection tube: contains 1 unit of trisodium citrate and 4 units of blood used for ESR test

Yellow blood collection tube: ACD is located in yellow blood collection tubes and is used for blood bank studies

The type of blood collection tubes

Blood collection tubes are made of polyethylene terephthalate (PET), polypropylene (PP), polyester, polyacrylic, polytetrafluoroethylene and polystyrene, etc.

PET and PP play the most important role in the production of blood collection tubes and are widely used. PET tubes are unbreakable and maintain a vacuum for a long time.

PP tubes have less permeability than PET

The outer wall of the tubes is made of PET because it is very transparent and the inside of the tubes can be seen

Surfactant materials are used to cover the inner layer, of course, the surfactant may be separated by contact with blood and interfere with the performed tests. To solve this problem, the manufacturers integrate the surfactant tubes with plastic.

Why are blood collection tubes made with colored lids?

The color of the lid of blood collection tubes has special reasons because each color has a specific function and this is recognized by medical nurses, for example, blood collection tubes with purple lids are often used for CBC. (production of blood collection tubes)

Also, the colored door is used as a kind of protection that does not threaten its infectious risks

The difference between a vacuum tube and a vacuum tube

Vacuum means vacuum and the difference between vacuum tube and non-vacuum is exactly here, that is, vacuum tubes have a vacuum exactly equal to the volume of blood that needs to be filled and they do not fill more than the standard volume. (production of blood collection tubes)

These types of tubes do not need to be filled with a syringe and receive blood directly from the needle and are filled. Another noteworthy advantage of these tubes is easy and safe maintenance, so that the risk of contaminating blood samples due to not opening the door until the moment of performing the tests is almost zero. (production of blood collection tubes)

But in non-vacuum tubes, these advantages do not exist, and the laboratory operator manually enters the blood collection tube from the syringe after receiving the blood from the patient.

Advantages of vacuum blood collection tube:

High speed in blood sample collection
Reducing the error in the collected sample volume
Increasing the quality of the collected sample
Ease and simplicity of use

Disadvantages of vacuum blood collection tubes:

Higher price compared to non-vacuum tubes
The need for special machinery for production and filling
