Abstract

The invention discloses a vacuum centrifugal machine, and belongs to the technical field of centrifugal machines. The vacuum centrifugal machine comprises a centrifugal machine body, a rotor and a vacuum pump. A centrifugal cavity is formed in the centrifugal machine body. The rotor is arranged in the centrifugal cavity and provided with a plurality of containing grooves. Hanging baskets are clamped in the containing grooves and used for containing to-be-centrifuged samples and can centrifuge the multiple samples at the same time without mutual interference. The distances between the hanging baskets and the rotating axis of the rotor are the same, so that the centrifugal effect of all the samples is consistent, the centrifugal efficiency is high, and installing and using are convenient. The vacuum pump is connected with the centrifugal machine body and used for pumping and draining gas in the centrifugal cavity, so that the temperature in the centrifugal cavity is lowered, the degeneration of the samples is prevented, and the quality of the centrifuged samples is ensured. The vacuum centrifugal machine is high in efficiency, the quality of the samples is not affected before and after centrifuging, the centrifugal effect is good, and the internal structure and installation are simple.

Description

technical field

[0001] The invention belongs to the technical field of centrifuges, in particular to a vacuum centrifuge. Background technique

[0002] A centrifuge is a device that separates mixtures of different specific gravity by centrifugal force. Among them, the rotor is an important component, the sample to be centrifuged is fixed on the rotor, and the centrifugation of the sample is completed by the high-speed rotation of the rotor. At present, the structure of the rotor is a split type, which is composed of a rotor body, a hanger pin, a collar and other components. The hanger pin is installed on the rotor and fixed by the collar. The structure is complicated, and it takes time and effort to disassemble. In addition, when the above-mentioned centrifuge rubs against the air during high-speed rotation, a large amount of heat is generated, which causes the temperature in the centrifuge cavity to rise rapidly. Since different samples to be centrifuged have different sen...
