4N6FLOQSwabs™ devices utilize proprietary flocked-swab technology to maximize DNA collection and elution efficiency. The perpendicular Nylon® fibers act like a soft brush, which improves collection of cellular material. Unlike traditional fiber wound swabs, 4N6FLOQSwabs™ devices have no internal absorbent core to disperse and entrap the specimen—the sample stays close to the surface for faster and more efficient elution.
