The EDTA K2 Blood Collection Tube with purple cap is a vacuum tube pre-filled with dipotassium ethylenediaminetetraacetic acid (EDTA K2), used for clinical blood sample collection and hematological analysis. The purple cap adheres to international color-coding standards, indicating its use for anticoagulated blood collection. This tube is designed to preserve the morphology and integrity of blood cells, making it essential for routine laboratory diagnostics.
Effective Anticoagulation
EDTA K2 works by binding calcium ions in the blood, efficiently preventing clot formation and ensuring high-quality specimens for complete blood counts (CBC) and other hematologic tests.
Preservation of Cell Morphology
The tube prevents distortion of red and white blood cells, maintaining the original cellular structure for accurate analysis.
Instrument Compatibility
Compatible with most automated hematology analyzers, supporting seamless laboratory operations.
High-Quality Material
Made from medical-grade PET for enhanced chemical stability and transparency. Each tube is designed to ensure safety and reliability in high-throughput environments.

The EDTA K2 tube is widely used in hospital laboratories, independent labs, blood banks, and research institutions due to its accuracy and consistency.
Tap the tube gently before use to distribute the additive evenly.
After blood collection, invert the tube 8–10 times gently to ensure proper mixing with the anticoagulant.
Do not centrifuge EDTA tubes for plasma separation. If plasma is required, use gel-containing tubes.
Perform testing within 2 hours for optimal results.

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.
