The large shed cell collector with EVA base is a forensic tool for wide-area sampling, using a flexible EVA base to recover shed cells from large surfaces efficiently.
Core Content
-
Design: Spacious textured sampling surface + lightweight EVA base (flexible to fit curved/large areas like furniture, vehicle seats).
-
Usage: Press EVA base firmly on target area; glide in overlapping strokes; transfer cells to collection card/tube.
Key Features
-
Wide sampling area: Covers 20-30 cm² per use, cutting time for large-surface evidence.
-
EVA base advantage: Flexible yet durable, maintains contact pressure on uneven surfaces.
-
High cell yield: Textured surface traps more shed cells than small collectors for large traces.
-
Forensic-ready: Sterile packaging, compatible with DNA extraction workflows.
Application Scope
-
Crime scenes: Large surfaces (car interiors, sofas, floors) for shed epithelial/blood cells.
-
Mass casualty events: Sampling large personal items or debris for victim identification.
-
Property crimes: Wide-area evidence on stolen furniture, electronics casings.
