Abstract

The invention discloses a nucleic acid extractor. The nucleic acid extractor comprises a case, a material tray, a plurality of suction heads, a liftable incubation mechanism, a magnetic adsorption assembly, a hanging basket and a guide rail, the material tray is provided with a plurality of detachable reagent plates, each reagent plate is provided with a sample tank, a lysis solution tank, a washing solution tank, an eluent tank, a waste solution tank and a reaction tank, and the reaction tanks is arranged at the rear ends of the reagent plate. The suction head is used for transferring a sample, a lysis solution, a washing solution, an eluent, a waste solution and nucleic acid, the incubation mechanism can heat the liquid in the reaction tank, and the magnetic forces of at least two magnets of the magnetic adsorption assembly are crossed, so that the magnetic force borne by the magnetic beads is increased, the magnetic adsorption time is shorter, and the effect is better. The hanging basket is ingenious in design structure, the centrifuge tubes can be taken out conveniently, and the centrifuge tubes are prevented from interfering with replacement of the reagent plate. The steps ofnucleic acid cracking, washing, elution, waste liquid treatment, nucleic acid transfer and the like are all completed in the extractor, so that the workload of personnel is reduced, and the nucleic acid extraction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a nucleic acid extractor. Background technique [0002] Nucleic acid extractor is an instrument that completes sample nucleic acid extraction. Nucleic acid extraction is widely used in disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial detection, food safety detection, animal husbandry and molecular biology research, etc. kind of field. Therefore, more and more people pay attention to biological detection. At present, the nucleic acid extraction steps are cumbersome and require a variety of equipment to be completed together. Nucleic acid extraction instruments have emerged as the times require. However, the current nucleic acid extraction instruments can only complete part of the extraction steps and have a huge structure. , the operation is cumbersome, which is not conducive to the work o...
