Abstract

The invention discloses a device for automatically extracting biological component on the basis of electromagnetic propulsion grinding and centrifugal separation, relating to the technical field of the automatic processing of biological samples. The device comprises a centrifugal mechanism, an electromagnetic propulsion module and a lifting mechanism, wherein the centrifugal mechanism is in a horizontal rotor structure; a series of centrifugal racks is evenly distributed around the axis on a centrifugal rotor body and can freely rotate between the horizontal direction and the vertical direction around the self axis; an operation bottle can be filled with certain amounts of biological samples and is provided with a grinding knocking body; and the operation bottle is fixed on the centrifugal racks and moves along with the centrifugal racks. When the automatic extraction device works, the operation bottle is inserted into the electromagnetic propulsion module, the grinding knocking body quickly moves back and forth under the driving of electromagnetic force and grinds; and then the operation bottle is extracted for centrifuging. The automatic extraction device has the advantages of compact structure and few moving components and can be widely applied to the automatic operation of extracting biological components, such as nucleic acid, protein and the like in the biological samples, such as animals, plants, microorganisms and the like.

Description

technical field [0001] The invention relates to the technical field of biological sample processing automation, in particular to an automatic extraction device for biological components based on electromagnetically driven grinding and centrifugal separation. Background technique [0002] In the field of molecular biology research and experiments, the separation and extraction of specific biological components such as nucleic acids and proteins from biological samples is a very common operation and the basis for all subsequent research and experiments.
