Embodiment Construction

[0034] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0035] Such as figure 1 , 2 , 3, 4, 5 are a kind of automatic nucleic acid extraction instrument of the present invention, and it comprises fuselage 100, workbench 200, swing mechanism 400, transmission mechanism 300, suction nozzle head 500, pressure gun 600, controller. The workbench 200 is provided with a test tube placement hole 201, a nozzle placement hole 202, a filtration hole 203, a cracking hole 204, a product collection hole 205 and a waste nozzle recovery tank 206. These execution stations are mainly used for corresponding Place test tubes, pipette tips, filter columns, etc. with reagents, and the swing mechanism 400 is used to drive the reciprocating movement of the workbench 200 in the width direction of the fuselage 100 (ie, the Y direction in the figure). The transmission mechanism 300 is used to drive the suction gun head 500 and the p...

Abstract

The invention discloses a full-automatic nucleic acid extraction machine which comprises a machine body, a workbench, a swing mechanism, a suction-injection gun head, a pressurization gun, a transmission mechanism and a controller, wherein the machine body at least comprises a rack; a test tube placing hole position, a suction nozzle placing hole position, a filter hole position, a cracking hole position, a finished product collection hole position and a waste suction nozzle recycling slot are formed in the workbench; the swing mechanism is used for driving the workbench to reciprocate relative to the rack; an opening at the upper end part of the suction-injection gun head is connected with an injection pump, and the lower end part is matched with a suction nozzle; an opening at the upper end part of the pressurization gun is communicated with a pressurization device, and an air outlet is formed in the lower end part; the transmission mechanism is used for driving the suction-injection gun head and the pressurization gun to move along the length direction and height direction of the machine body; and the controller is used for controlling the transmission mechanism and the swing mechanism. The nucleic acid extraction machine disclosed by the invention can realize automatic suction and injection of samples and reagents, thus improving the working efficiency; and moreover, during filtration, positive pressure is applied to a filtering tubular column by the pressurization gun, the filtering time is shortened, and the nucleic acid extraction efficiency is further improved.

Description

[0001] technical field [0002] The invention relates to the technical field of nucleic acid extraction, in particular to an automatic nucleic acid extraction instrument. [0003] Background technique [0004] Nucleic acid extraction technology is widely used in the fields of biology and medicine. Obtaining high-purity nucleic acid from biological samples is a prerequisite for accurate nucleic acid testing, especially for biological samples extracted in polluted environments. Particularly important. [0005] In view of the importance of the nucleic acid extraction process and its universal applicability, almost all nucleic acid purification laboratories related to biomolecules and medical treatment are equipped with nucleic acid extraction instruments, which are used to replace traditional manual experimental extraction methods, Avoid sample contamination and improve the purity of the extracted nucleic acids. With the continuous development of new technologies in the biol...
