Product Overview
Lavender Top EDTA K3 Vacuum Blood Collection Tubes are designed for the collection of whole blood samples for clinical laboratory use. Each tube contains liquid tripotassium ethylenediaminetetraacetic acid (K₃EDTA) as an anticoagulant. These tubes feature an internationally recognized lavender cap and are commonly used in complete blood counts (CBC), white blood cell analysis, blood typing, and molecular diagnostics. The pre-set vacuum ensures accurate blood volume, while the liquid K₃EDTA provides consistent anticoagulation and excellent sample preservation.
Key Features
Efficient Anticoagulation
The liquid K₃EDTA disperses evenly inside the tube, preventing clot formation and preserving cell morphology for reliable results.
International Color Code
The lavender-colored cap aligns with global laboratory standards, making the tubes easy to identify and sort.
Accurate Vacuum Draw
Each tube is vacuum-sealed to draw a consistent blood volume, ensuring standardized sample processing.
Durable Tube Materials
Available in high-strength PET plastic or medical-grade glass, both offering excellent sealing and pressure resistance.
