Automated Nucleic Acid Extraction Workstation SAW-48


The Automated Nucleic Acid Extraction Workstation SAW-48 (referred to as "SAW-48" below) produced by Jiangsu Bioperfectus Technologies Co., Ltd. is an in-vitro diagnostic medical device that integrates cutting-edge mechanical, electronic, and software technologies. SAW-48 integrates sample loading, nucleic acid purification, and PCR setup functions in one instrument. The typical run duration is less than 45 minutes for 1-48 samples. Based on experienced magnetic separation technology, SAW-48 provides high throughput automation combined with high performance. It will promote laboratory productivity to meet changing needs. With non-contact dispensing of samples, reagents, and PCR reagents, it will be safe and simple for the operators and save time and money for the laboratory.


  • Integrated stationWalk-away system from primary sample tube to PCR ready-to-go tube, including sample loading, nucleic acid purification, and PCR setup operations
  • Customizable Workflow: Pre-programmed protocols tailored to different requirements
  • Fast Speed: 1-48 samples with the whole process in 45 minutes
  • User-friendly design: visual interface with functions real-timely shown in software
  • Better contamination control: UV light, HEPA filter, and the electrostatic filter will help prevent the inside environment from aerosols. Scientific zoning, a pipette device equipped with a leak-proof design, and filter pipette tips will enhance the anti-cross-contamination level.
