The Sterile 2ml Vacuum Tube with EDTA K2 is a high-quality blood collection device designed for accurate hematology testing and laboratory diagnostics. Manufactured using medical-grade materials and strict quality control standards, this tube ensures reliable anticoagulation and sample stability for clinical and research applications.
This product is widely used in hospitals, diagnostic laboratories, research institutions, and clinical trial centers that require precise blood analysis and consistent test results.
Reliable Anticoagulation Performance
The tube contains K2EDTA anticoagulant, which effectively chelates calcium ions to prevent blood clotting. This ensures that blood samples remain in whole blood form, preserving cellular integrity for accurate hematology analysis.
Vacuum Collection System
Each tube is pre-evacuated to draw a precise blood volume automatically, reducing operator variability and improving sampling consistency. The vacuum design also enhances workflow efficiency in clinical settings.
Sterile and Medical-Grade Materials
The tube is manufactured from medical-grade PET or glass and sterilized to eliminate contamination risks. This makes it suitable for clinical diagnostics and sensitive laboratory testing.
2ml Volume for Micro-Sampling
The 2ml capacity is ideal for pediatric sampling, small-volume blood draws, and research applications where minimal blood volume is required.
Leak-Proof Cap and Clear Labeling Area
The secure cap design prevents leakage during transport, while the smooth label area allows easy patient and sample identification.

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.
