Single sample nucleic acid enclosed extractor

Abstract

The invention provides a single sample nucleic acid enclosed extractor. The single sample nucleic acid enclosed extractor comprises a cabin with safety door, the inner top surface of the cabin is provided with a magnetic bead moving mechanism, the inner bottom surface of the cabin is provided with a test tube group, an accommodating tube is processed on the test tube group, and a magnetic bar protective jacket is placed in the accommodating tube; the sidewall of the cabin is provided with a fan and a ventilation port for supplying air outside; the magnetic bar protective jacket is provided with a clamp hole; the inner top surface of the cabin is provided with a test tube cover moving mechanism, and a magnetic bar central axis in the magnetic bead moving mechanism, a test tube cover opening mechanical arm central axis in the test tube cover moving mechanism and a test tube central axis in the test tube group are in the same vertical plane. The single sample nucleic acid enclosed extractor avoids cross contamination among samples, the test tube is sequentially enclosed after each step, interference between test tubes is avoided, so that high-quality and high-purity extraction result can be obtained, and nucleic acid extraction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of nucleic acid extraction, and relates to a nucleic acid extraction instrument, in particular to a single-sample nucleic acid closed extraction instrument. Background technique [0002] Acid extraction and purification is almost accompanied by the entire molecular biology research process, from the initial target gene extraction to PCR product purification or "gel recovery", as well as the extraction of plasmids in gene cloning and other experimental processes, are inseparable from nucleic acid extraction and purification, nucleic acid extraction Work is basically repetitive labor without any technical content. [0003] Nucleic acid extraction and purification is the starting point of molecular biology research, so nucleic acid extractors are widely used, including genomics research, such as extraction of DNA or RNA from animals, plants, microorganisms or viruses; molecular diagnosis of clinical samples, CDC; animal ...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the automatic nucleic acid extractors use the magnetic bead method to extract nucleic acid. During the extraction process, the test tube mouth is open, and they are all test tube groups designed for multi-sample extraction. The test tube group is an open extraction The test tubes on the platform and the test tube set are not covered with test tube covers, which is easy to cross-contaminate during the nucleic acid extraction process, and the final extraction results are also placed in open test tubes

Moreover, these extraction devices are bulky, costly, and require a large amount of consumables
