Problems solved by technology

[0003] Nucleic acid extractors are usually used to extract nucleic acids. Nucleic acid extractors generally use magnetic beads to absorb nucleic acids, and finally separate nucleic acids from magnetic beads to complete nucleic acid extraction. Therefore, the degree of collection of magnetic beads is proportional to the degree of nucleic acid extraction. Because magnetic beads The particles are small, and the magnetic beads are distributed everywhere in the test tube when th

Description

technical field [0001] The invention belongs to the technical field of nucleic acid extraction, and in particular relates to a nucleic acid extraction device. Background technique [0002] In the nucleic acid extraction operation of the magnetic bead method, whether the mixing of the magnetic beads and the free nucleic acid is sufficient, and whether the magnetic rod is completely adsorbed to the magnetic beads are crucial to the nucleic acid extraction effect, especially the magnetic bead mixing operation and magnetic bead adsorption of large-volume samples. Particularly important. For the routine small-capacity nucleic acid extraction work, when extracting nucleic acid, the magnetic rod and the free nucleic acid are mixed evenly through the up and down reciprocating motion of the magnetic rod, the rotary motion of the magnetic rod sleeve, and the suction and discharge of the pipette. The magnetic beads adsorb nucleic acid, and then the magnetic rod adsorbs the magnetic be...
