Nucleic acid purification system with anti-pollution effect

Abstract

The invention relates to the technical field of nucleic acid extraction, and discloses a nucleic acid purification system with an anti-pollution effect, the nucleic acid purification system comprises a main body, the main body is internally provided with a test area and a filter area, and the top of the main body is connected with a telescopic cylinder through a fixing frame. According to the nucleic acid purification system with the anti-pollution effect, the main body, the test area, the filter area, thse fixed rod, the connecting plate, the sealing plate, the fixed ring, the test glove, the external thread ring, the air inlet pipe, the dust filtering cover, the fan, the sterilization pipe, the UV ultraviolet lamp, the sterilization filter and the exhaust pipe are matched with one another, so that the under the combined action of the fan, the UV ultraviolet lamp and the sterilization filter, the sterile air is continuously introduced into the test area, so that the test area is always in a positive pressure state, bacteria are prevented from entering the test area, the effect of reducing the possibility that an extracted sample is polluted by the outside world is achieved, and the problem that the extracted sample is easily polluted by the outside world when nucleic acid is extracted by using a chromatographic column method is solved.

Description

technical field [0001] The invention relates to the technical field of nucleic acid extraction, in particular to a nucleic acid purification system with anti-pollution effect. Background technique [0002] The nucleic acid purification system can use supporting nucleic acid extraction reagents to complete the extraction of sample nucleic acid. Common nucleic acid extraction methods include chromatography column method, pyrolysis method, nano magnetic bead method, etc., among which the chromatography column method is the most commonly used in the market. Nucleic acid extraction method, which can adsorb DNA through special silica-based adsorption materials, while RNA and protein can pass through smoothly, and then use high salt and low pH to bind nucleic acid, and use low salt and high pH value to elute to separate and purify nucleic acid. [0003] When using the chromatography column method to extract nucleic acids in the laboratory, it is necessary to continuously mix differ...
