Abstract
A hybrid metal/composite centrifuge is described which can be designed and manufactured for large sizes which have traditionally been of metal construction only. The hybrid metal/composite centrifuge combines an “all composite”, fully disposable, centrifuge rotor with a reusable metal center tube which retains the rotor bearings. This design combines a fully disposable composite rotor, for example made of an incinerable plastic material, with a removable and reusable metal centertube.
Claims6
A centrifuge comprising:
- a composite rotor made entirely from incinerable material, the rotor includes a first opening at one end and a second opening at an opposite end;
- and
- a metal centertube that supports the composite rotor, the metal centertube includes a first end that extends through the first opening and a second end that extends through the second opening;
- a first bearing mounted on the centertube at the first end and a second bearing mounted on the centertube at the second end for rotatably supporting the metal centertube, and the centertube is removably mounted on the rotor.
1 more element
A centrifuge comprising:
- a composite rotor made entirely from incinerable material, the rotor includes an upper, outer rotor shell that is sealed along a base edge thereof to a lower rotor base along a seam to define an interior space in which centrifugal separation occurs;
- a first opening is formed centrally in the outer rotor shell and a second opening is formed centrally in the lower rotor base opposite the first opening;
- and
- a metal centertube that supports the composite rotor, the metal centertube includes a first end that extends through the first opening and a second end that extends through the second opening;
- a first bearing mounted on the centertube at the first end and a second bearing mounted on the centertube at the second end for rotatably supporting the metal centertube, and the centertube is removably mounted on the rotor.
