Centrifuge rotor having a predetermined region of failure

摘要: A centrifuge rotor (10) is characterized by a portion of the undersurface (22B) thereof being removed to define predetermined number bosses (26) each with sample receiving cavity (30) therein. relatively thin skirt (38) extends between at least one pair adjacent (26). The has defined thereon localized region (12) which exhibits stress therein that greater than present in any other when operating speed. may have weight (42) thereon. be either separate from or formed integrally (38). Additionally alternatively, riser (46) form hole(s), notch(es) groove(s), on skirt. Over operation time, probability failure will occur only enhanced.
