Biological Evidence Collection Swab III

Biological Evidence Collection Swab III prevents DNA contamination, ensures high transfer efficiency, and simplifies two-step dry/wet sampling with protective caps.

Description

The Biological Evidence Collection Swab III is engineered with precisely controlled manufacturing parameters to ensure a specialized fiber winding structure, enhancing DNA transfer and release efficiency. Its performance equals or exceeds that of flocked swabs. Each swab features a dual-tip design with clearly marked “Dry” and “Wet” ends for two-step sample collection.

Key Features:

  • Prevents exogenous DNA contamination with sterile, DNA-free raw materials and automated production under strict cleanroom conditions.

  • Dual protective caps keep swab tips suspended, avoiding contact with external surfaces or evidence bags.

  • DNA transfer and release efficiency match or exceed imported flocked swabs due to optimized microstructure fiber winding.

  • Free from chemicals that could damage DNA, including hypochlorite residues, ensuring high-quality DNA purification.

  • Stringent quality control including STR testing guarantees no exogenous DNA contamination.

  • Two-step dry/wet swab design simplifies handling and prevents sample mix-ups.

  • Ventilated protective cap enables rapid air-drying of wet swabs for safe storage.

Technical Parameters:

  • Packaging: 40 swabs per box

  • Swab type: Dual-tip, dry/wet

  • Fiber: Specially wound cotton for optimal DNA transfer and release

  • Protection: Individual dual protective caps

  • Quality control: STR-tested, exogenous DNA-free

Usage Instructions:

  1. Use the wet swab for initial sampling, followed by the dry swab for secondary collection.

  2. After collection, cover both swab tips with protective caps.

  3. Store swabs in evidence bags; wet swab dries quickly through ventilated cap.

Application Range:
Forensic, clinical, and laboratory DNA collection from surfaces, materials, or biological evidence where contamination prevention and high DNA recovery are critical.
