Product Description
EDTA anticoagulant tube purple cap, ethylenediamine tetraacetic acid (EDTA, molecular weight 292), and its salt are amino polycarboxylic acids that can effectively chelate calcium ions in blood samples. Cheating calcium or removing the calcium reaction site will block and terminate the endogenous or exogenous coagulation process to prevent the coagulation of blood samples.
What Are K2 EDTA Blood Collection Tubes?
K2 EDTA tubes are vacuum-sealed blood collection tubes that contain two potassium ions chelated with EDTA. The primary purpose of these tubes is to collect whole blood samples for hematological analysis while preventing clot formation. The purple cap colour indicates that the tube contains EDTA and is specifically designed for tests requiring whole blood or plasma.

Features of K2 EDTA Tubes
Anticoagulant Properties: K2 EDTA effectively prevents blood from clotting by binding to calcium ions, which are necessary for the coagulation cascade.
Colour-Coded Identification: The purple cap colour makes it easy to identify K2 EDTA tubes in a clinical setting.
Volume Options: K2 EDTA tubes are available in various volumes, typically ranging from 2 mL to 10 mL, depending on the specific requirements of the laboratory tests.
Material Composition: These tubes are usually made from polyethylene terephthalate (PET), ensuring durability and resistance to breakage.
Sterile and Single-Use: K2 EDTA tubes are sterile and intended for single-use to prevent contamination and ensure sample integrity.
How does K2 EDTA work as an anticoagulant?
K2 EDTA works by chelating calcium ions in the blood, which are essential for the coagulation process. By binding to these ions, it prevents the activation of clotting factors, keeping the blood in a liquid state.
What is the difference between K2 and K3 EDTA tubes?
The main difference lies in the number of potassium ions present. K2 EDTA contains two potassium ions, while K3 EDTA contains three. K2 EDTA is generally preferred for routine hematology tests due to its lower hyperosmolarity.
