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 K3 EDTA Blood Collection Tubes?K3 EDTA blood collection tubes that contain three 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.The Use of Different K3 EDTA Blood Collection TubesVolume/mlSize/mmAdditiveSeparatorMaterialCap ColorClosure2ml13X75EDTA K2 / EDTA K3/PET/GLASSPurple Cap TubeSafety Cap Rubber or Rubber Stopper3ml13X75EDTA K2 / EDTA K3/4ml13X75EDTA K2 / EDTA K3/5ml13X75EDTA K2 / EDTA K3/6ml13X100EDTA K2 / EDTA K3/7ml13X100EDTA K2 / EDTA K3/8ml16X100EDTA K2 / EDTA K3/9ml16X100EDTA K2 / EDTA K3/10ml16X100EDTA K2 / EDTA K3/If You Need a Customized customized Blood collection tube, Please Contact UsFeatures of K2 EDTA TubesAnticoagulant Properties: K3 EDTA effectively prevents blood from clotting by binding to calcium ions, which are necessary for the coagulation cascade.Color-Coded Identification: The purple cap color makes it easy to identify K3 EDTA tubes in a clinical setting.Volume Options: K3 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 durable PET plastic, ensuring resistance to breakage and maintaining sample integrity.Sterile and Single-Use: K3 EDTA tubes are sterile and intended for single use to prevent contamination and ensure sample integrity.What is the purpose of using K3 EDTA in blood collection?K3 EDTA works by binding to calcium ions in the blood, which are necessary for the coagulation process. This prevents clotting and preserves the integrity of blood samples for accurate testing.What is the purpose of using K3 EDTA in blood collection?K3 EDTA works by binding to calcium ions in the blood, which are necessary for the coagulation process.
