Sterile Water 3mL Ampoules (100 per box)

Sterile water ampoules are used to apply on a swab to collect DNA from various surfaces.

When applying the sterile water to the DNA swab, NEVER touch the tip of the water ampoule to the swab and apply no more than 4 drops to the DNA swab to avoid over saturation.  The swabs must be packaged in a porous container, swab box, envelope, or paper bag.
