Abstract

The invention discloses a biomolecule extraction device which comprises a casing. At least one group of actuating mechanism capable of eccentrically oscillating a sample to be extracted and a control system capable of controlling the actuating mechanism to move is arranged in the casing. The actuating mechanism can automatically and eccentrically oscillate the sample to be extracted, thereby greatly improving the experiment efficiency. The invention adopts the optimal scheme that the actuating mechanism not only comprises a power frame component, but also comprises a heating component for heating the sample to be extracted on a rotary frame. While being eccentrically oscillated, the sample is heated to be more conducive to the extraction of biomolecules (such as DNA (Deoxyribonucleic Acid)). As the biomolecule extraction device can oscillate while being heated, the temperature is reduced while overheating, so that the test efficiency is greatly improved.

Description

technical field [0001] The present invention relates to a device for extracting biomolecules based on magnetic field force, in particular to a device for extracting and taking biomolecules from samples through multifunctional integration methods such as high-speed rotation mixing, heating, and cooling combined with a certain reagent. Background technique [0002] Life science is an experimental science. A large number of biological experiments and clinical diagnosis are inseparable from sample preparation. The extraction and purification of biomolecules are widely used in sample preparation. With the development of biotechnology, the number of samples processed in clinical diagnosis and biological experiments is increasing, and the demand for automation is becoming more and more urgent. [0003] Most of the existing simple biomolecule extraction devices only have the function of magnetic bead adsorption, that is, the magnetic frame, and do not integrate the functions of magn...
