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.

hat is the difference between EDTA K2 and K3 in blood collection tubes?
EDTA K2 and 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.

Why are EDTA tubes widely used in hematology tests?
EDTA tubes are widely used in hematology tests because EDTA prevents blood coagulation by chelating calcium ions. This ensures accurate results for complete blood counts (CBC) and blood cell morphology studies, making it essential for reliable diagnostics in clinical settings.

How long can blood samples be stored in EDTA K2 K3 tubes?
Blood samples in EDTA K2 K3 tubes can typically be stored for up to 24 hours at room temperature. For longer storage, refrigeration is recommended, but it’s best to process samples as soon as possible to ensure accuracy.
