Improvacuter 4ml EDTA K3 vacuum blood collection tubes are designed for precise and efficient hematology testing. These tubes utilize Ethylenediaminetetraacetic acid (EDTA K3) as an anticoagulant, effectively preventing blood coagulation by chelating calcium ions. The dry or liquid EDTA K3 coating on the inner tube wall ensures a consistent concentration of 1.2-2.0 mg (0.00411-0.006843 mol/L) of dry EDTA per 1 ml of blood, conforming to ISO 6710 standards.
Designed for seamless integration with automated hematology analyzers, these tubes feature a pierceable rubber stopper, eliminating the need to open the tube. Simply invert the tube gently 180 degrees after blood collection for thorough mixing. The tubes are 13x75 mm in size with a 4ml capacity and are identified by their distinctive purple cap. These high-quality tubes ensure reliable and accurate results for your hematology analyses. They are specifically designed for whole blood samples.
