Product Overview
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.
Key Features
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.

Applications
Complete Blood Count (CBC)
Hemoglobin and Hematocrit Testing
Blood Typing and Crossmatching
Erythrocyte Sedimentation Rate (ESR)
Hematology research and clinical diagnostics
The EDTA K2 tube is widely used in hospital laboratories, independent labs, blood banks, and research institutions due to its accuracy and consistency.
Instructions for Use
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.
