Abstract

The invention discloses a nucleic acid extraction device for a nucleic acid extraction instrument, which comprises a device body and a door panel; a door panel is rotatably installed on one side of the device body; a placement device is arranged in the device body, and the bottom end of the placement device is symmetrically rotated and installed There are support rods, and two sets of support rods are arranged in parallel, and the bottom ends of the support rods are rotatably installed in both sides of the bottom end of the device body; the middle part of the bottom end of the support rods is provided with a coil spring, and the coil springs are sleeved on the rotating shaft , the two ends of the coil spring are respectively against the bottom end of the square groove and the square block, and the two sets of coil springs are arranged symmetrically; the square block is fixedly installed in the middle of the bottom end of the support rod; A baffle is fixedly installed symmetrically, and a pressing device is provided on the side of the baffle away from the placement device. The device of the present invention makes the nucleic acid extractor vibrate continuously through the rotation of the pressing rod and the characteristics of the coil spring, so that the mixed liquid can be mixed quickly and evenly, and the oscillating effect is good and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nucleic acid extraction device for a nucleic acid extraction instrument. Background technique [0002] Nucleic acid is a biological macromolecular compound synthesized by many nucleotides, and is one of the most basic substances of life. Nucleic acid widely exists in all animal and plant cells and microorganisms. Nucleic acid in organisms is often combined with protein to form nucleoprotein. Different nucleic acids have different chemical compositions and nucleotide arrangement sequences. [0003] The current nucleic acid extraction reaction system is generally below 1ml, but many experiments need to extract free nucleic acid from a large number of samples, which requires a large volume of experimental samples of the reaction system. The stirring of the sample mixture is usually carried out by manually shaking the nucleic acid extractor to stir the sample mixture. M...
