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.

Key features

  • Designedfor rapid absorption and superior sample release, enabling increased assay sensitivity and performance for both reference and casework samples
  • Pre-scored breaking point allows for easy breaking of the swab into tubes for processing
  • Certified free of DNase, RNase, and amplifiable human DNA; uses only selected non-inhibitory components
  • Available in a variety of ergonomic designs, configurations, and customizable collection kits
  • ETO-treated (Ethylene Oxide)

Designed specifically for reference sample collection:
The unique 4N6FLOQSwabs™ DNA Collection Reference Sample product line is specifically designed for faster absorption and more efficient sample release as compared to traditional swabs.

  • Validated for direct PCR amplification, therefore single source samples collected with 4N6FLOQSwabs™ devices can be easily processed using the Applied Biosystems® Prep-n-Go™ Buffer, eliminating the need for extraction steps
  • Available in different formats to enhance sample preservation to meet the varied needs of forensic and paternity laboratories
