[0002] With the progress and development of molecular biology, high-throughput nucleic acid extraction technology has become a hot topic in the research of biological related fields. Magnetic bead method for nucleic acid extraction has been widely used due to its advantages of simple operation and high degree of automation. In the process of magnetic bead method for nucleic acid extraction, a magnetic bar is provided on the magnetic frame, and the reaction tube is usually placed between the magnetic bars of the magnetic frame or on the hollow magnetic bar.
