Thixotropic gel can be found in some tubes, including Becton-Dickinson's SST tube with the red-gray marbled top and PST tube with the green-gray marbled top.The density of this synthetic gel is between that of red cells and plasma or serum, and it settles between the two during centrifugation, forming a barrier.This barrier facilitates retrieval of the liquid portion without cellular contamination.
