GeneFiX RNA Saliva Collection

GeneFiX™ is a new easy to use RNA saliva collection device that stabilizes RNA from the moment of collection for 2 weeks. 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. The unique funnel design prevents flow back and can also be used with our new assisted option using foam swabs, and the device is fully specified for sample transport and storage.
