Serum gel tubes contain an inert barrier gel that is present in the bottom of the tube. During centrifugation the barrier gel moves upward to the serum - clot interface, where it forms a stable barrier separating the serum from fibrin and cells. VACUETTE® Serum Tubes with Gel improve the serum yield and enable serum to be left in the primary tube. Vacuette Lithium Heparin Tube The wall of the VACUETTE® Heparin tubes is coated with spray-dried lithium, ammonium or sodium heparin. The additives are anticoagulants, which block the coagulation cascade and prevent coagulation of the blood sample. Plasma gel contain an inert barrier gel that is present in the bottom of the tube. During centrifugation the barrier gel moves upward to the plasma - cell interface, where it forms a stable barrier separating the plasma from cells. VACUETTE® Plasma Tubes with Gel improve the plasma yield and enable plasma to be left in the primary tube. Vacuette Flouride Oxalate Tube Both sodium fluoride and iodoacetate are used in VACUETTE® Glucose Tubes as glycolysis inhibitors to preserve glucose when combined with an anticoagulant such as EDTA, potassium oxalate or heparin. The tubes are suitable for determining glucose and lactate. Vacuette EDTA Tube
