Product Overview
The 9ML EDTA Vacuum Blood Collection Tube for Laboratory is a reliable solution for collecting and preserving blood samples in clinical and research settings. Pre-loaded with a precise concentration of EDTA (either dipotassium or tripotassium), the tube effectively chelates calcium ions in the blood, preventing coagulation and preserving the original state of the sample. It is widely used for complete blood counts, blood typing, molecular biology tests, and other diagnostic applications.
Design Features and Structural Advantages
The tube is made from high-clarity PET or crystal glass, providing excellent transparency to monitor the sample’s condition. It features a medical-grade butyl rubber stopper with outstanding sealing performance and puncture recovery, compatible with most standard blood collection needle systems. The purple (lavender) safety cap follows international color coding for easy identification. Inside, the EDTA anticoagulant is precisely measured to match the 9 mL draw volume, ensuring accurate results without interference from incorrect anticoagulant ratios.

Working Principle and Anticoagulation Mechanism
EDTA (Ethylenediaminetetraacetic acid) binds to calcium ions in the blood, forming stable chelates. This process blocks the conversion of prothrombin to thrombin and inhibits fibrin formation, effectively preventing clotting while preserving cell morphology. This is particularly important for hematology tests, blood smear preparation, and component analysis. For molecular biology applications, EDTA helps minimize nucleic acid degradation, improving the accuracy of DNA and RNA testing.
Clinical and Research Applications
The 9ML EDTA Vacuum Blood Collection Tube for Laboratory is used in a wide range of fields:
Hematology: Red blood cell, white blood cell, and platelet counts, along with differential analysis.
Blood Typing and Crossmatching: For pre-transfusion compatibility testing.
Molecular Biology: Suitable for DNA and RNA extraction, as well as PCR amplification.
Immunology: Flow cytometry, immunophenotyping, and related assays.
Sample Preservation: Maintains stability for delayed testing or long-distance transportation under proper storage conditions.
Instructions for Use and Precautions
Pre-collection Check: Verify the tube’s expiration date, vacuum status, and absence of cracks or defects.
Blood Collection: Use a compatible blood collection needle and holder, filling to the 9 mL mark.
Mixing: Gently invert the tube 8–10 times immediately after collection to mix the blood with the anticoagulant. Avoid vigorous shaking to prevent hemolysis.
Storage: Store samples between 4°C and 25°C and test within the recommended time frame for the specific analysis.
Single Use: Dispose of the tube according to medical waste handling protocols after use.
Summary
The 9ML EDTA Vacuum Blood Collection Tube for Laboratory combines high-clarity materials, precise anticoagulant formulation, excellent sealing, and stable vacuum performance to deliver dependable results for both clinical diagnostics and research. Its proven effectiveness in hematology, molecular biology, and immunology testing has earned the trust of laboratories and healthcare facilities worldwide.
