GeneFix DNA Saliva Collectors

GeneFix DNA Saliva Collectors

GeneFix is an easy to use DNA saliva collection device that stabilizes DNA long term in an integrated stabilization buffer. The collector is pre-filled and has a screw-on funnel for simple saliva delivery directly into the buffer. The assisted option includes foam swabs for donors who have difficulty with saliva delivery. With leak-proof collection tubes, GeneFix is fully specified for sample transport and storage. Options with 2D barcoded tubes specially designed to be rackable and robotic compatible are also available. 

The buffer in GeneFix DNA Saliva Collectors can also stabilize viral RNA for a few days at room temperature.
