Obtain accurate and efficient plasma results with our high-quality 9ml Improvacuter vacuum blood collection tubes containing sodium heparin. These tubes are ideal for biochemical analyses requiring plasma, offering several key advantages over serum: faster turnaround time, increased sample volume, independent results from coagulation status, results closely reflecting in vivo blood conditions, and reduced risk of hemolysis and thrombocytosis.
Each tube is pre-coated with dry sodium heparin (12-30 IU/ml) on the inner wall, preventing blood clotting upon collection. After blood collection, gently invert the tube 5-8 times. Centrifuge immediately at 1300g for 10 minutes.
