Title (EN) CENTRIFUGE ROTOR HAVING STRUCTURAL STRESS RELIEF
(FR) ROTOR DE CENTRIFUGEUSE PRESENTANT UNE CARACTERISTIQUE DE DETENTE
Abstract:
(EN) A centrifuge rotor with a body (10) having a spin axis (12) and a plurality of bores (22) formed therein, each of which is adapted to support a centrifuge container (30). The rotor includes a load reducing (52) feature to decrease the loading between the rotor body and the centrifuge container, during centrifugation. The load reducing feature includes separating a portion of an annular shoulder (42) of a centrifuge container from the rotor body. The portion of the annular shoulder that is separated is disposed between the spin axis and the bore associated with the centrifuge container.
(FR) Rotor de centrifugeuse dont le corps (10) possède un axe de rotation (12) et une pluralité de cavités (22) conçues chacune pour loger un réservoir (30) de centrifugeuse. Ce rotor présente une caractéristique (52) de diminution de charge servant à diminuer la charge entre le corps du rotor et le réservoir (30) pendant la centrifugation. On réalise cette caractéristique de diminution de charge au moyen de la séparation d'une partie d'un rebord annulaire (42) d'un réservoir et du corps du rotor. La partie séparée du rebord annulaire est placée entre l'axe de rotation et la cavité associée au réservoir de centrifugeuse.
