After proper centrifugation, serum can be left in contact with the gel barrier of SST tubes for up to 5 days with proper storage. Blood from a single donation or sample can be separated into different components: proteins, red blood cells, white blood cells, clotting factors, etc., and used for their individual purposes. Serum blood collection tubes promise to provide unpolluted and undifferentiated original blood samples for medical testing.After centrifugation, serum can be effectively separated from blood cells and fibrin.There are three types of serum tubes: plain tube with red cap, a red cap precoagulation tube, and a yellow cap coagulation gel activator tube. Serum Separator Tubes (Gold Top) Serum separator tubes contain a clot activator and a separation gel. Normally, i keep blood at room temperature for around 3-4 hours.
