Embodiment Construction

[0039] figure 1 A centrifuge rotor 10 according to the invention is shown with a lower part 12 and a cover 14 . In principle, the centrifuge rotor 10 is made of metal, preferably a metal containing aluminium.

[0040] In the lower part 12 there are holes 16 for receiving sample vessels (not shown). Additionally, the lower portion 12 has a shaft support 18 for accommodating a suitable laboratory centrifuge 100 (e.g., 5430R laboratory centrifuge, not shown) drive shaft (see Figure 4 ).

[0041] Furthermore, the lower part 12 has a first locking device 20 known to the skilled person (for example from FA-45-48-11 fixed-angle rotor), the rotor also includes a rotor nut 22, and the centrifuge rotor 10 is fixed on the drive shaft through the rotor nut 22.

[0042] The cover 14 has a second locking device 24 known to those skilled in the art (for example FA-45-48-11 fixed-angle rotor), the second locking device 24 has an actuating element 26 through which the user (not shown) ...

Abstract

The invention relates to a centrifuge rotor (10) in which the seal (34) between the lower part (12) and the cover (14) of the centrifuge rotor (10) is substantially improved. Said seal (34) used according to the invention is more efficient and durable. It also facilitates the opening and closing process.

Description

technical field [0001] The invention relates to a centrifuge rotor with a seal. Background technique [0002] Centrifuge rotors are used in centrifuges, especially in laboratory centrifuges, to use the inertia of mass to separate the components of a sample centrifuged therein. For this purpose, higher and higher rotational speeds are used to achieve high separation rates. A laboratory centrifuge is a centrifuge whose rotor is preferably at least 3000 revolutions per minute, preferably at least 10000 revolutions per minute, especially at least 15000 revolutions per minute, usually placed on a table. In order to be able to place them on a bench, they especially have a form factor of less than 1m x 1m x 1m, so that their installation space is limited. Preferably, the device depth is limited to a maximum of 70 cm. [0003] In most cases, samples are centrifuged at a certain temperature. For example, samples containing proteins and similar organic substances must not be overh...
