GeneFix is an easy to use saliva collection device that stabilizes DNA and viral RNA in tubes pre-filled with a non-toxic stabilization buffer. FDX collectors are supplied with 2D FluidX barcoded tubes for identification.

FDX-01 is developed for 1ml of saliva. The collector has a simple screw-on funnel for saliva delivery directly into the buffer. Once in the buffer, DNA is stabilized for 5 years and viral RNA is stabilized for 5 days at room temperature, with high yields maintained.

The 2D FluidX barcoded tubes are specially designed to be rackable and robotic compatible and can be used in auto de-capping machines. These leakproof tubes are fully specified for sample transport and storage. 

Below is a demonstration of how to use the GeneFix Saliva Collectors:



  • Special FluidX tube is 2D barcoded for identification
  • Rackable and robotic compatible; can be used in auto de-capping machines
  • Integrated DNA/RNA stabilization buffer preserves high yields of DNA and viral RNA
  • DNA stabilized for 5+ years and viral RNA for 5 days at room temperature
  • Unique funnel design prevents spillages or buffer flow back
  • Total DNA yield in adults is 180ng/µl
  • Ready for transport; collection tube specified to 95kPa for leakproof mailing



  • Saliva DNA and viral RNA collection and stabilization
