Key Features

1. Accurate Anticoagulation:

EDTA K2 or K3 works by chelating calcium ions, effectively preventing coagulation and maintaining cell integrity for precise test results.

2. PET Tube Construction:
Made from high-quality polyethylene terephthalate (PET), the tube offers excellent transparency, impact resistance, and leak-proof performance, ensuring safety during sample handling and transport.

3. Spray-Dried EDTA Coating:
The inner wall of the tube is coated with spray-dried EDTA K2 or K3, rather than a liquid form, which minimizes dilution and maintains the original blood composition for reliable test accuracy.

4. Secure Closure System:
The cap is made of medical-grade butyl rubber with a high-quality plastic shell, designed to maintain vacuum stability and prevent contamination. It also supports smooth piercing and resealing during sample processing.

What is the difference between EDTA-K2 and EDTA-K3 in blood collection tubes?
EDTA-K2 and EDTA-K3 are both anticoagulants used in blood collection tubes. EDTA-K2 is in liquid form, while EDTA-K3 is in powdered form. Both prevent blood coagulation by chelating calcium ions, ensuring accurate hematology test results. The choice depends on specific laboratory requirements.

Can EDTA-K2/EDTA-K3 tubes be used for serum tests?
No, EDTA-K2/EDTA-K3 tubes are not suitable for serum tests. They are designed for whole blood tests, particularly hematology studies. For serum tests, tubes without anticoagulants, like red top tubes, are recommended.
