The fully automatic nucleic acid extractor developed by the R&D department of Shanghai Xiongtu Biotechnology Co., Ltd. can be used for extracting and purifying sample nucleic acids using magnetic bead or membrane adsorption methods. By selecting the corresponding reagent kit, high-purity nucleic acids can be automatically separated and purified from various sample materials such as blood, tissues, and cells. It has the advantages of strong compatibility, fast extraction speed, high extraction recovery rate, and easy operation, and is a powerful "assistant" for molecular biology laboratory testing and experimentation. It can be widely applied in fields such as scientific research, molecular diagnosis, and detection of animal and plant diseases.
