Embodiment Construction

[0029] Please refer to Figure 1 ~ Figure 3 , a preferred embodiment of the present invention provides a magnetic rod sleeve 100 . The magnetic rod sleeve 100 includes a side wall 110 and a bottom plate 120 . The side wall 110 and the bottom plate 120 define a cavity 111 with an opening for accommodating a magnetic bar. The magnetic rod sleeve 100 also includes a stirring structure 130 for stirring the reagent solution and a docking structure for docking with the power mechanism 310 of the nucleic acid extraction instrument. The stirring structure 130 is disposed on the side wall 110 and / or the bottom plate 120 . The docking structure is disposed on the side wall 110 . The magnetic rod sleeve 100 cooperates with the magnetic rod, and is opposed to the power mechanism 310 of the nucleic acid extractor through the docking structure, thereby rotating under the drive of the power structure, and stirring the reagent solution through the stirring structure 130, thereby achieving ...

Abstract

The invention relates to magnetic rod pipe sleeves, a multi-link assembly and a nucleic acid extraction instrument. The nucleic acid extraction instrument comprises the multi-link assembly, a fixing device and a power mechanism, wherein the power mechanism drives the magnetic rod pipe sleeves to rotate and is connected with the fixing device. The magnetic rod pipe sleeves, the multi-link assembly and the nucleic acid extraction instrument have the beneficial effects that the magnetic rod pipe sleeves on the multi-link assembly are driven by the power mechanism to rotate at high speed relative to a support plate; the rotation speeds of the magnetic rod pipe sleeves can be adjusted by adjusting the speed of the power mechanism, so that the requirement of flow of high-viscosity magnetic beads can be met; stirring structures stir reagent liquid at high speed by driving the magnetic rod pipe sleeves to rotate at high speed, thus eliminating the phenomenon of splash of the reagent liquid, widening the uniformly mixed area, fully adsorbing, washing and eluting the magnetic beads, greatly increasing the nucleic acid yield and also reducing the nucleic acid extraction instrument production cost.

Description

technical field [0001] The invention relates to the technical field of nucleic acid extraction, in particular to a magnetic rod sleeve, a multi-connection component and a nucleic acid extraction instrument. Background technique [0002] Extracting cells, as well as biologically active substances such as proteins and nucleic acids, plays an important role in modern molecular biology research, clinical disease diagnosis, blood transfusion, food safety testing and other fields. Among them, nucleic acid is a biologically active substance compound synthesized by many nucleotides, which is one of the most basic substances of life. Nucleic acid is widely present in all animals, plant cells, microorganisms, and organisms. According to different chemical composition, nucleic acid can be divided into ribonucleic acid, referred to as RNA and deoxyribonucleic acid, referred to as DNA. DNA is the main material basis for storing, replicating and transmitting genetic information, and RNA...
