FAQ
Why is preservation by desiccation better than a liquid preservative?
Drying the sample eliminates the need for liquid to be added to the sample. This allows for clean, easy collection process without the chance of spilling a solution and shipping is much easier without a tube of liquid, allowing for very flat packages that save money.
Why is a CollectEject Swab better than other swabs?
The cotton head of a CollectEject Swab has the advantage of being highly absorbent compared to other materials, but the layer design instead of a spun cotton enables a complete DNA extraction. The swab head ejects with a plunger.
