The Medical Lavender EDTA Vacuum Blood Collection Tube is designed for precise and consistent blood sampling in clinical laboratories, diagnostic centers, and hospitals. Featuring EDTA as the anticoagulant and a standardized lavender-colored cap, this tube is widely used for hematology testing where the preservation of cellular morphology is critical.
Manufactured under strict quality control standards, this EDTA vacuum blood collection tube ensures stable anticoagulation, accurate sample volumes, and reliable performance across routine and advanced laboratory applications.
A lavender-top EDTA tube is a vacuum blood collection device pre-filled with a measured amount of EDTA anticoagulant. EDTA works by binding calcium ions in the blood, effectively preventing clot formation while maintaining the integrity of blood cells.
The lavender cap serves as an internationally recognized identifier for EDTA-treated tubes, helping laboratory professionals quickly select the correct tube during blood collection and processing. This type of tube is specifically intended for tests that require whole blood or plasma with minimal cellular distortion.

The precisely dosed EDTA ensures complete anticoagulation without affecting cell size or shape, supporting consistent test results.
Each tube is manufactured with controlled vacuum pressure to ensure proper blood draw volume, reducing pre-analytical variability.
Produced using medical-grade plastic or glass, the tube offers excellent chemical resistance and durability during handling and centrifugation.
The rubber stopper provides reliable sealing to prevent leakage and contamination, while allowing smooth needle penetration.
The transparent tube body allows easy inspection of the sample volume and condition.
The Medical Lavender EDTA Vacuum Blood Collection Tube is commonly used for:
Complete Blood Count (CBC)
White blood cell differential analysis
Hemoglobin and hematocrit testing
Blood typing and cross-matching
Molecular diagnostics requiring EDTA-preserved samples
Its ability to preserve cellular structure makes it an essential consumable in hematology laboratories.
Perform venipuncture using standard blood collection procedures.
Allow the vacuum to draw blood until the preset volume is reached.
After collection, gently invert the tube 6–8 times to mix the blood with the EDTA anticoagulant.
Avoid vigorous shaking to prevent hemolysis or platelet activation.
Store and process samples according to laboratory testing requirements.
Proper mixing is essential to ensure uniform anticoagulation and reliable test outcomes.

EDTA tube is a type of blood collection tube that contains ethylenediaminetetraacetic acid (EDTA) as an anticoagulant. EDTA works by binding to calcium ions in the blood, which prevents clotting and helps preserve the sample for laboratory analysis.
The primary purpose of using EDTA tubes is to collect blood samples for various laboratory tests, particularly those related to blood cell counts and blood typing. EDTA helps maintain the integrity of the blood sample by preventing coagulation and ensuring reliable test results.
EDTA works by chelating calcium ions in the blood, which are essential for the coagulation process. By binding these ions, EDTA prevents clot formation.
Sinymedical offers K2 and K3 EDTA tubes, which differ in the number of potassium ions they contain, catering to various laboratory needs.
K2 EDTA tubes contain dipotassium EDTA, while K3 EDTA tubes contain tripotassium EDTA, differing in concentration and specific applications.
Both types effectively prevent clotting, but the choice between them may depend on specific laboratory protocols and test requirements.
Yes, K2 EDTA tubes are suitable for most hematological tests, including complete blood counts (CBC) and blood typing.
K3 EDTA tubes are often used in specialized applications where a higher concentration of potassium is needed, such as certain molecular assays.
Store EDTA tubes at room temperature (4-25°C) and avoid exposure to extreme temperatures or direct sunlight to maintain their effectiveness. It is important to check the expiration date on the tubes and avoid using expired products
EDTA tubes can be purchased from various medical supply companies, laboratory equipment suppliers, and online retailers for high-quality EDTA tubes.
