It is about the tubes used to obtain blood products through centrifuge in order to cure open and closed injuries to heal hard and soft tissues and to diagnose in all fields of medicine and dentistry. Platelet Rich Fibrin (PRF) obtained in the tubes the surface of which contacts blood and made from pure titanium or titanium alloys has a better structure of fibrin than that is obtained through classical methods. The efficiency of the high speed centrifuge is increased with this designed tube and Platelet Rich Fibrin can be removed from the tube without spoiling it.
