When the sample-filled tube is subjected to centrifugation the gel migrates and forms a physical barrier between the plasma and most of the cellular elements.

. In both cases the occlusion was caused by inappropriate gel barrier formation after centrifugation 2000 g for 10 min at room temperature of the primary tubes. Gel-barrier mottled redgray gold or cherry red-top tubes contain clot activator and gel for separating serum from cells but include no anticoagulant. SST Becton Dickinson AutoSep Terumo and Microvette Sarstedt all of which contain an inert barrier eg gel for cleaner separation of serum from coagulum during centrifugation.
