Product Overview

The EDTA K2 Gel Vacuum Blood Collection Tube is a widely used consumable in clinical laboratories and research institutions. Pre-loaded with K₂EDTA anticoagulant and a gel separator, the tube effectively prevents blood coagulation and forms a stable barrier during centrifugation, ensuring the separation of plasma from blood cells. It provides high-quality plasma samples, making it ideal for molecular diagnostics, virology tests, and genetic studies.

Key Features

• Stable Anticoagulation: K₂EDTA, evenly sprayed on the tube wall, rapidly chelates calcium ions, preventing clotting.
• Efficient Plasma Separation: The gel forms a clear barrier after centrifugation, reducing contamination and ensuring pure plasma.
• Material Options: Available in both PET plastic and glass tubes to meet different laboratory requirements.
• Accurate Blood Collection: Pre-set vacuum ensures precise and consistent blood volume.
• Wide Range of Sizes: Volumes available from 2ml to 15ml, suitable for multiple applications.

The Use of Different Vacuum EDTA + Gel Tubes

Instructions for Use

1. Follow the correct order of drawing to avoid cross-contamination.
2. After collection, gently invert the tube 8–10 times to mix the blood with the anticoagulant.
3. Centrifuge according to laboratory protocols; the gel will form a stable separation barrier.
4. Use the plasma directly for testing or store under recommended conditions.

Applications

1. Clinical Testing

Suitable for complete blood counts (CBC), plasma biochemistry, and blood cell morphology analysis, ensuring accuracy and reproducibility.

2. Molecular Diagnostics

Widely applied in viral nucleic acid testing (HIV, HBV, HCV, SARS-CoV-2, etc.), where gel separation minimizes cellular contamination and enhances test sensitivity.

3. Genetic Testing & Precision Medicine

Ideal for DNA/RNA extraction, sequencing, tumor gene detection, and pharmacogenomic studies, supporting personalized medicine.

4. Hematology & Research

Used in blood cell studies, plasma protein analysis, and immunology research, providing reliable samples for clinical and laboratory investigations.

Precautions

• Check tube integrity before use; do not use if vacuum is lost or damaged.
• Avoid vigorous shaking to prevent hemolysis.
• Mix samples immediately after collection to prevent micro-clot formation.
• Single-use only; dispose of according to medical waste protocols.
• Use within the validity period to ensure anticoagulant performance.
