● Purpose: it is used for rapid blood sample collection in biochemical, immune and other clinical medical testing centers. The coagulant added in the blood collection vessel is different from other chemical coagulation methods in terms of its impact on the test results. The coagulant is evenly sprayed on the inner wall of the blood collection vessel. Without the help of any heating facilities (such as water temperature tank, etc.), it adopts pure Physicalization to make the blood solidify rapidly. After blood collection, stand still for 15-30 minutes. After the blood is completely coagulated, centrifuge on the machine to obtain ideal and high-purity serum.
