Abstract
A centrifuge rotor (10) includes a closure (32) between a lower part (12) of the centrifuge rotor (10) and a cover (14). The centrifuge rotor has been improved such that proper single-handed operation is made possible. In particular, the closure (32) can be closed and detached again using just one hand. The cover (14) includes a circular cut-out (20) for fastening the centrifuge rotor (10) in a centrifuge. The cover (14) is attached to the lower part (12) by levers having a concave shaping (66). The cover (14) and the levers cooperate to provide a visual indication whether the cover is properly closed.
Claims14
A centrifuge rotor (10), comprising:
- a lower part (12);
- and
- a cover (14),
- wherein the centrifuge rotor (10) has a rotational axis (D),
- wherein the cover (14) can be placed onto the lower part (12) along the rotational axis (D) in a closing direction (S) and can be removed along the rotational axis (D) in a detaching direction (L),
- wherein, when the cover (14) is closed, there is a closure (32) between the lower part (12) and the cover (14), and
- wherein at least one element selected from the group consisting of the lower part (12) and the cover (14) comprises at least one first undercut (34), in which, when the cover (14) is closed, at least one projection (36) engages, which is arranged on another element from the group consisting of the cover (14) and the lower part (12),
- wherein the projection (36) is arranged on a lever (24) having a fulcrum (38), and wherein the fulcrum (38) is arranged on the cover (14)
- wherein the cover (14) comprises a circular cut-out for fastening the centrifuge rotor (10) in a centrifuge,
- wherein the lever (24) has a concave shaping (66) which continues the circular cut-out and points towards the rotational axis (D), and
- wherein the lever (24) is arranged such that, when the cover (14) is closed, the concave shaping (66) does not project inwards into the circular cut-out.
