The Siny Medical All Type Vacuum Blood Collection Tubes offer a complete solution for accurate and safe blood sample collection. Available in EDTA, Sodium Heparin, Serum Separator, and ESR types, these tubes are designed to meet various laboratory and clinical diagnostic needs with precision and reliability.
Each tube is manufactured under CE-certified quality standards, ensuring consistent vacuum pressure, precise anticoagulant volume, and airtight sealing for contamination-free collection. Ideal for hematology, biochemistry, and immunology tests, Siny vacuum tubes provide stable samples and dependable performance, making them the preferred choice for hospitals, research centers, and diagnostic laboratories worldwide.
A vacuum blood collection tube is a device used to collect blood samples, which consists of a hollow plastic tube and a rubber plug attached to the tube. A certain negative pressure is established inside the vacuum collection vessel in advance to automatically suck blood into the tube. During blood collection, medical personnel inserts a needle into a hole in the rubber plug, and blood is vacuumed into the tube to complete the blood collection process. The advantage of vacuum sampling is that it is easy to operate, fast, and can reduce pollution and error.

Siny offers four main tube types EDTA tubes for hematology, Sodium Heparin tubes for plasma analysis, Serum Separator tubes for biochemical testing, and ESR tubes for erythrocyte sedimentation rate tests. Each type ensures accurate results through precise anticoagulant formulation and vacuum-sealed design.
The Siny tubes are CE, ISO, and FDA certified, ensuring compliance with international quality and safety standards. These certifications guarantee superior product reliability, sterility, and precision suitable for global medical and laboratory applications.
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.
