NIII TEST vacuum sterile tubes with sodium heparin filler are designed for the study of plasma, heparinised blood, used for counting blood cells.
Vacuum tubes simplify the procedure of blood collection for medical personnel. They guarantee the safety of patients and doctors, excluding direct contact with blood, as they contain ready-made chemical additives depending on the type of research and are colour-coded according to international standards.
The characteristics of vacuum tubes are determined by the type of filler, the size of the tube and the volume of the blood sample taken.
