K3 EDTA Blood Collection Tubes are a critical component in modern clinical laboratories and diagnostic centers, widely used for the collection of whole blood specimens, particularly in hematological testing. These tubes contain tripotassium salt of ethylenediaminetetraacetic acid (EDTA), which acts as an effective anticoagulant by binding to calcium ions in the blood. Calcium is essential for the clotting cascade, and by chelating it, K3 EDTA prevents coagulation, ensuring the preservation of the sample’s cellular components for accurate analysis.
 
K3 EDTA Blood Collection Tubes are typically identified by their distinctive purple or lavender-colored caps, which provide easy visual identification in high-volume laboratory settings. Available in various volumes ranging from 2 mL to 10 mL, these tubes cater to different test requirements. The standard sizes include 13×75 mm and 16×100 mm dimensions, ensuring compatibility with most automated blood collection and analysis systems. Both PET plastic and glass materials are used in manufacturing these tubes, offering durability and resistance to breakage during handling and transportation.
