Cat#: SGC-50
Sales Price$167.00

Easy-to-use capsules for stabilizing DNA on SK-1S buccal swabs for 3+ years.

Isohelix Dri-Capsules were developed to quickly and efficiently dry SK-1S swabs to maintain complete molecular biology integrity while avoiding DNA cross contamination risks. 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.  

To use, simply insert the capsule into the 5ml collection tube, included with each SK-1S swab, along with the used swab and seal the tube securely with the cap provided. Long term stability studies show that DNA samples on SK-1S swabs stored with Isohelix Dri-Capsules are stabilized for over 3 years

Dri-Capsules can also be purchased as a kit with 50 SK-1S swabs.
