GeneFiX™ Saliva DNA/RNA Collection
GeneFiX™ is an easy to use DNA and RNA saliva collection device that stabilizes DNA long term in 2ml and now the latest 1ml saliva sample options.

GeneFiX™ Saliva DNA/RNA Collection Device
The collector is pre-filled and has a simple screw-on funnel for simple saliva delivery directly into the non-toxic stabilization buffer. The saliva collection tube clearly indicates the volume of saliva required after which the funnel is removed and cap replaced. Various tube options are now available for both manual and HT or Automated Rackable formats. The unique patented*¹ funnel design prevents flow back and can also be used with our assisted option using foam swabs to collect saliva from babies, elderly or any donor unable to use the funnel. The device is fully specified for sample transport and storage.
GeneFiX™ Xtra DNA Collect
The ‘Xtra DNA Collect’ is designed to collect 3ml of Saliva thus improving yields over the standard GeneFix and 1ml and 2 ml collectors. It is packaged in the same tube yet filled with 1ml of a higher concentration buffer to allow for extra dilution of the saliva. It has most of the benefits of our standard collector and will appeal to scientists requiring maximal yields even in cases where patient sampling times may be extended. Currently in house and ongoing studies show full 2 year stabilization but we feel confident this will be extended over time.
GeneFiX™ Assisted Saliva
The Assisted Collection kit includes two foam swabs to allow collection from infants, elderly or otherwise impaired donors. Various tube options are now available for both manual and HT or Automated Rackable formats. The unique patented*¹ funnel design prevents flow back.The device is fully specified for sample transport and storage.
