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.
