Description

technical field [0001] The invention relates to a medical analysis device, in particular to an automatic nucleic acid extraction instrument. Background technique [0002] In the detection of modern molecular biology, molecular diagnosis and detection technology based on nucleic acid are increasingly showing a vital role in many fields. In molecular detection, the primary problem is to quickly and efficiently extract and isolate the required nucleic acids from biological samples. Nucleic acid extraction is the starting point of downstream detection and genotyping, and is one of the most critical basic methods of molecular biology. It has widely penetrated into various life fields such as biology, genetics, and medicine. The quality and integrity of extracted and separated nucleic acids will It directly affects the subsequent detection efficiency and accuracy, and plays a key role in connecting the past and the future. [0003] Operations such as precipitation and centrifuga...
