Our FlexSTAR workflow increases both the quality and productivity of genomic DNA isolation with its (+/Plus) integration, offering simplified, pure gDNA isolation from primary sample tube to DNA storage tube.

  • Load up to 30 samples from a variety of primary tube sizes directly onto the instrument
  • Includes protocols for 0.5 to 10ml whole blood
  • Includes our saliva protocols allow you to process up to 30, 4ml saliva tubes at a time
  • Plus protocols for buffy coats derived from 10ml (30 at a time) or 20ml (15 at a time)
  • Automated sample transfer from primary tubes with linear and 2D barcode scanning and LIMS/LIS integration 
  • Additional protocols for cultured cells, packed cells, PBMC, and more

Ask us about our pre-barcoded tube units to reduce hands-on time, as well as our new SBS Tri-coded storage tubes.






The FlexSTAR+ (FlexSTAR workflow with (+/Plus) integration) is our fully automated solution for gDNA extraction and isolation from large volumes of blood, saliva,  buffy coats, and more. Our FlexSTAR+ is the first and only totally automated system utilizing Qiagen’s FlexiGene chemistry to isolate genomic DNA free of RNA and other contaminants.  The FlexSTAR+ also offers full sample tracking and LIS interfacing.  This proven precipitation chemistry produces pure, high molecular weight gDNA ready for immediate use and long-term storage.

Principle & Procedureimage1
  1. Lysis buffer is added to the sample (e.g. blood) and cell nuclei and mitochondria are pelleted by centrifugation
  2. The pellet is resuspended and incubated in denaturation buffer containing a chaotropic salt and QIAGEN Protease – efficiently removing contaminants (e.g. proteins)
  3. DNA is precipitated by the addition of isopropanol, recovered by centrifugation, washed in 70% ethanol, dried, and resuspended in hydration buffer (10mM Tris·Cl, pH 8.5)
