Embodiment Construction

[0015] figure 1 A centrifuge rotor 2 is disclosed and a cover 4 is depicted being placed on the centrifuge rotor 2 by a user's hand (not shown). The centrifuge rotor 2 has a row of holes or compartments 6 evenly distributed around the periphery of the rotor, into which test tubes (not shown) inclined outwardly at the bottom can be inserted. Overall, the rotor is rotationally symmetrical about a vertical axis 8 and has in the center a vertical central hole 9 through which the rotor 2 can be inserted onto a centrifuge drive shaft (not shown in the figures) Centrifuge.

[0016] The compartment 6 is accessible for the test tubes through a large circular opening 10 at the top of the rotor 2 . They are situated on the radially outer wall of a bowl-shaped chamber 11 which extends annularly around a central axis 12 .

[0017] Arranged on the bottom side of the shaft 12 is the hole 9 for the drive shaft of the centrifuge rotor. Towards the top, the shaft 12 projects cylindrically t...

Abstract

The present invention relates to a lid for closing a centrifuge rotor, characterized by a positively locking rotation-activated closing mechanism, which, prepositioned on the centrifuge rotor, moves automatically into a closed position by virtue of the intrinsic weight of the lid.

Description

technical field [0001] The invention relates to a cover for closing the rotor of a centrifuge. Background technique [0002] A centrifuge is a device that subjects a container to centrifugal force. In the laboratory, for example, suspensions in test tubes can be treated in such a way that suspended solid matter settles to the bottom of the test tube. Typically, centrifuges have a rotary drive with a vertical drive shaft on which a rotor can rest. A plurality of compartments are usually provided in the rotor, into which the containers to be centrifuged can be inserted. The multiple rotors of a centrifuge are often interchangeable so that the contents of a container in one of the rotors are centrifuged while the other has just been loaded with containers, or may be ready for further processing with already centrifuged containers. [0003] For example, since the test tube is pushed into the rotor so that the top is open, operational reliability is achieved by, among other th...
