EDTA

VACUETTE® EDTA tubes are used for determinations in EDTA whole blood for haematology, immunohaematology or for the molecular biological identification of viruses, parasites and bacteria after centrifugation and plasma for clinical chemistry.

EDTA tubes from Greiner Bio-One are available in three versions: K2E K2EDTA, K2E K2EDTA Separator and K3E K3 EDTA.

The additive potassium EDTA (ethylenediaminetetraacetic acid) contained in the tube interferes with calcium and thus blockades the coagulation cascade.
