StoolFiX™ Gut Microbiome Stabilization

The New StoolFiX Gut Microbiome Collection and Stabilization pre-filled tubes use the latest Isohelix™ DNA Stabilization chemistry, fully optimized for fecal microbiome DNA.

To minimize sample handling, the Isohelix DNA swabs are used to collect and transfer the sample into prefilled tubes containing the StoolFiX™ buffer. Once sealed the buffer protects the DNA integrity and maximizes yield for months at room temperature.

The robust tube is well suited to shipping, combining the collection, transportation and storage of samples into one tube.


  • Ambient Stability – Maintains Integrity Long Term
  • Isohelix™ Swab Matrix – Maximizes DNA Yield
  • Minimized Handling – Improves Reliability and Compliance
  • Transport Tested – At-home sampling
