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:
-
Use the wet swab for initial sampling, followed by the dry swab for secondary collection.
-
After collection, cover both swab tips with protective caps.
-
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.
