Hard-base shed cell collectors are forensic tools for trace sample extraction, using rigid bases to recover cells from uneven/rough crime scene surfaces.
Core Content
-
Design: Sturdy plastic base with textured sampling surface + ergonomic grip for controlled pressure.
-
Usage: Press on target (tool grooves, wood); scrape linearly; transfer cells to collection tube.
Key Features
-
Uneven surface fit: Rigid base maintains contact where soft swabs struggle.
-
Targeted sampling: Accesses narrow crevices/textured materials precisely.
-
High retention: Textured surface traps trace cells for reliable DNA recovery.
-
Sterile: Single-use packaging prevents cross-contamination.
Application Scope
-
Crime scenes: Tools, wooden surfaces, textured metals for touch DNA.
-
Vehicle forensics: Tire treads, gear shifts, dashboard crevices.
-
Burglary cases: Door locks, window frames, broken glass edges.
