Isohelix™ Dri-Capsules

The capsules are highly efficient with a non-toxic coating containing a high grade silica gel with a color indicator to display continued active stabilization.

All components are rigorously batch and DNA tested to defined and stringent quality standards prior to assembly within the highest specification multi-laminate moisture barrier foil, which maintains and guarantees the Dri-Capsules performance over the long term and in varying temperatures and humidities.


  • Long term stability at room temperature
  • Reduces DNA cross contamination
  • Non-toxic and inert coating, very easy to handle
  • Ideal for remote and field sample collection

Long term stability studies show that the stability of DNA samples on SK-1S swabs stored with Isohelix™ Dri-Capsules is maintained over a period of at least 3 years. The ongoing study is expected to confirm an increased period of stabilization well in excess of the 3 years tested so far.
