Fig. 1

Final sizes of PRF clots produced utilizing 3 different centrifugation tubes in each of 3 different centrifugation devices (a) total of 9 tested groups). (A) Final PRF clot weight sizes depicted when different groups of tubes are used. (B) Final PRF clot weight sizes depicture when different centrifugation systems were utilized. Notice that in general, the IntraSpin centrifugation device produced slightly large clots (roughly 15%), whereas the glass tubes (Process for PRF, Salvin) produced the largest PRF clots (roughly 200–250% larger than those produced with plastic silica-coated IntraSpin tubes).
