Dual-Tip Forensic Swabs: DNA Collection & Storage

Posted on by
Dual-ended forensic swabs have two specialized heads, optimizing DNA collection and preservation from crime scene biological evidence efficiently.

Key Content

  • Heads Design: Flocked nylon (trace DNA) and foam/cotton (liquid/large samples) for diverse evidence.
  • Usage: Swab targets, snap handle to place heads in separate tubes, label and transport at 2–8°C.

Core Features

  • High efficiency: One tool for two samples, cutting processing time.
  • Low contamination: Sterile packaging and separate tubes reduce risks.
  • Enhanced yield: Flocked head recovers 30–50% more trace DNA.
  • Court-admissible: Meets chain-of-custody standards.

Application Scope

  • Violent crimes: Weapons, clothing in assaults/homicides.
  • Property crimes: Burglary tools, stolen items, entry points.
  • Cold cases: Re-sampling old evidence for hidden DNA.
  • Disaster ID: Personal items/remains in mass casualties.
