Micro-DNA Flocked Swab: Efficient Elution & Protection

Posted on by
The micro-DNA collection flocked swab is a specialized tool for micro-scale DNA sampling, prioritizing efficient cell elution and sample protection for forensic and research use.

Core Content

  • Design: Ultra-fine 3D flocked nylon head (max cell capture) + thin, flexible shaft; compatible with microcentrifuge tubes.
  • Usage: Swab trace micro-DNA surfaces; immerse head in elution buffer; vortex briefly for high cell recovery; store at 2–8°C.

Key Features

  • High elution efficiency: Releases 90%+ captured cells, outperforming traditional cotton swabs for micro-samples.
  • Sample protection: Flocked structure minimizes cell damage during collection and elution.
  • Micro-scale focus: Ideal for low-volume samples like single-cell or trace touch DNA.
  • Sterile: Single-use packaging prevents cross-contamination in sensitive sampling.

Application Scope

  • Forensic micro-sampling: Trace DNA on small surfaces (jewelry, tool tips, electronic components).
  • Molecular research: Single-cell DNA collection or microbe sampling in lab experiments.
  • Clinical diagnostics: Low-volume biological samples for genetic testing or pathogen detection.

Rapid-Dry Flocked Swabs: Trace DNA Collect & Preserve

Posted on by
Rapid-dry flocked swabs are specialized for trace DNA collection, with fast-drying tech ensuring long-term sample preservation for forensic analysis.

Core Content

  • Design: Ultra-fine 3D flocked nylon head (max cell capture) + breathable shaft; enables 15-30min air-dry time.
  • Usage: Swab trace DNA surfaces (touch, saliva); air-dry fully; store in moisture-proof bag with desiccant.

Key Features

  • Rapid drying: Minimizes microbial growth and DNA degradation post-collection.
  • High trace yield: Flocked head traps 40-60% more cells than standard cotton swabs.
  • Long-term preservation: Stable DNA storage for 12+ months at room temp when dried.
  • Forensic-ready: Sterile, single-use, supports chain-of-custody protocols.

Application Scope

  • Crime scenes: Touch DNA on weapons, electronics, door handles, clothing.
  • Cold cases: Re-sampling old evidence for previously undetected trace DNA.
  • Forensic labs: Processing low-level DNA samples for profiling and court evidence.
