Claims
- 1. A centrifuge system comprising:a rotor; a container assembly which comprises a container, a lid on a top of said container, and a member positioned between said lid and an upper portion of said container; and means for holding said container about said rotor, wherein said member abuts a first surface and a second surface of said holding means, wherein said holding means supports said member, and said member supports said lid, and wherein said member transfers a centrifugal force from said lid to said holding mean, and thus prevents said centrifugal force from being transferred to said upper portion of said container.
- 2. The system according to claim 1, wherein said holding means is a swinging bucket.
- 3. The system according to claim 1, wherein said member includes a first lip that engages an edge of said lid, and a second lip that engages said surfaces of said holding means.
- 4. The system according to claim 1, wherein said upper portion of said container includes a shoulder, and said member has a sloping portion substantially conforming to a contour of said shoulder.
- 5. The system according to claim 1, wherein said member includes an aperture for receiving said lid, and a flange that engages an edge of said lid.
- 6. The system according to claim 1,wherein said container includes a neck having (a) an aperture for providing access to said container, and (b) a first threaded surface, and wherein said lid includes a second threaded surface that engages said first threaded surface.
- 7. The system according to claim 1, wherein said container is non-cylindrical.
- 8. The system according to claim 1,wherein said container comprises a bag, an d a neck having (a) an aperture for providing access to said bag, and (b) a first threaded surface, and wherein said lid includes a second threaded surface that engages said first threaded surface.
- 9. The system according to claim 8, wherein said container assembly comprises a weld for attaching said neck to said bag.
- 10. The system according to claim 1, wherein said container is made of a plastic selected from the group consisting of polyethyleneterephthalate, polypropylene, and polycarbonate.
- 11. A container assembly for use in a bucket of a centrifuge, said bucket having first and second surfaces, said container assembly comprising:a container having a neck and an upper portion; a lid for scaling said container; and a member disposed between said lid and said upper portion, and having a contour for abutting said first surface and said second surface of said bucket, wherein said member, when said container assembly is installed in said bucket, supports said lid and transfers a centrifugal force from said lid to said bucket, and thus prevents said centrifugal force from being transferred to said upper portion of said container.
- 12. The assembly according to claim 11, wherein said member includes a first lip for engaging an edge of said lid, and a second lip for engaging an edge of said bucket.
- 13. The assembly according to claim 11, wherein said upper portion of said container includes a shoulder, and said member has a sloping portion substantially conforming to a contour of said shoulder.
- 14. The assembly according to claim 11, wherein said member includes an aperture for receiving said lid, and a flange that engages an edge of said lid.
- 15. The assembly according to claim 11,wherein said neck includes (a) an aperture for providing access to said container, and (b) a first threaded surface; and wherein said lid includes a second threaded surface that engages said first threaded surface.
- 16. The assembly according to claim 11, wherein said container is non-cylindrical.
- 17. The assembly according to claim 11,wherein said container comprises a bag; wherein said neck includes (a) an aperture for providing access to said bag, and (b) a first threaded surface; and wherein said lid includes a second threaded surface that engages said first threaded surface.
- 18. The assembly according to claim 17, further comprising a weld for attaching said neck to said bag.
- 19. The assembly according to claim 11, wherein said container is made of a plastic selected from the group consisting of polyethyleneterephthalate, polypropylene, and polycarbonate.
- 20. A bridge for supporting a lid on a container that is disposed within a centrifuge rotor, said rotor comprising first and second intersecting surfaces, said bridge comprising:a first lip for engaging an edge of said lid; and a second lip for engaging an edge of said rotor at the intersection of said first surface and said second surface of said rotor when said container is placed within said rotor, wherein said rotor supports said bridge, and said bridge supports said lid, and wherein said bridge transfers a centrifugal force from said lid to said rotor, and thus prevents said centrifugal force from being transferred to an upper portion of said container.
- 21. The bridge according to claim 20, further comprising a substantially horizontal portion having an aperture, wherein said first lip is a flange disposed about an end of said aperture.
- 22. The bridge according to claim 20, further comprising a sloping portion substantially conforming to a contour of a shoulder of said container, wherein said second lip is adjacent to an edge of said sloping portion.
- 23. The bridge according to claim 20, wherein said bridge is substantially reverse U-shaped.
- 24. The bridge according to claim 20, wherein said bridge is made of polypropylene.
