EDTA Vacutainer Enamel Pin
Ethylenediaminetetraacetic acid (EDTA) is an anticoagulant used in blood collection tubes and tissue culture analysis. EDTA chelates the calcium present in the blood specimen, arresting the coagulation process and preserving blood cell morphology. So grab your lavender tube, and lets do some CBCs!
