BD Vacutainer® K2 EDTA Tube, Lavender Hemogard Closure, 100 per Box

BD Vacutainer® K2 EDTA Tubes are made from polyethylene terephthalate (PET) and spray-coated EDTA (ethylenediaminetetraacetic acid). Tubes are used for whole blood hematology determinations, immunohematology testing, and blood donor screening. EDTA is used to anticoagulate whole blood for haematological investigations as the cellular components of the blood are particularly well preserved by EDTA. It works as an anticoagulant as it forms complexes with metal ions such as calcium, therefore inhibiting the coagulation cascade.
