Description

Technical Field

[0001] This utility model belongs to the technical field of nucleic acid extraction devices, and in particular relates to an oscillation structure for a nucleic acid extraction device. Background Technology

[0002] The oscillating structure of the nucleic acid extraction device can effectively promote the rupture of cells and the release of nucleic acids in the sample by generating high-frequency vibrations. It is mainly used to accelerate sample mixing and reaction, and ensure efficient release and separation of nucleic acids. The structure uses mechanical vibration or rotational motion to make the sample fully contact the lysis solution, thereby promoting cell lysis and nucleic acid release.

[0003] The oscillation structure of existing nucleic acid extraction devices often uses a combination of multiple power sources to achieve nucleic acid extraction. For example, circular rotation mixing requires one power source to provide kinetic energy, while vertical reciprocating oscillation requires another power source to provide kinetic energy. Using multiple power sources increases the cost of use, resulting in unsatisfactory performance.

[0004] To address these issues, we provide an oscillating structure for a nucleic acid extraction device. Utility Model Content
