The forensic cotton swab with dual sampling heads is a specialized tool for forensic evidence collection, enabling efficient dual-sample gathering with sterile cotton tips.
Core Content
-
Design: Dual cotton sampling heads (high-absorbent) on a sturdy plastic shaft; individually sealed in sterile packaging.
-
Usage: Use one head for primary sample collection, the other for duplicate/secondary sampling; place each in separate preservation tubes.
Key Features
-
Dual sampling: Two heads allow simultaneous or sequential collection without extra tools, saving time.
-
Sterile assurance: EO-sterilized cotton tips and packaging prevent cross-contamination of evidence.
-
High absorbency: Cotton material effectively captures liquid and trace biological samples (blood, saliva).
-
Cost-efficient: Reduces tool count while maintaining quality for multiple evidence points.
Application Scope
-
Crime scenes: Collecting bloodstains, saliva, or epithelial cells from weapons, clothing, or surfaces.
-
Forensic labs: Providing duplicate samples for parallel DNA testing and result verification.
-
Field investigations: Limited-tool scenarios needing dual samples (e.g., remote crime scenes).
