Small-Size Shed Cell Collector

Description

The Small-Size Shed Cell Collector is designed for efficient collection of trace shed cells from both smooth and uneven surfaces. It features a low-viscosity pressure-sensitive adhesive film mounted on an elastic EVA plastic block, enclosed in a protective transparent plastic case to prevent contamination. The collector is sterilized via ethylene oxide and handled under strict clean conditions to ensure DNA-free sampling. Ideal for forensic investigations and DNA laboratories, it allows safe, contamination-free collection, transport, and DNA extraction of trace cells.

Key Features:

• Thin adhesive film easily fits into centrifuge tubes for DNA extraction

• Elastic EVA block ensures close contact with surfaces of varying flatness, maximizing cell collection

• Protective plastic case prevents contamination during storage and transport

• Ethylene oxide sterilization eliminates residual DNA, ensuring a DNA-free product

• Label on the case allows proper documentation of evidence information

Technical Parameters / Packaging:

• Plastic case size: 44 × 42 × 13 mm

• EVA plastic block: 30 × 10 × 10 mm

• Adhesive film: 10 × 10 mm, low-viscosity pressure-sensitive adhesive

• DNA sterilization: Full production under cleanroom conditions; ethylene oxide sterilization post-assembly

Usage Instructions:

1. Remove EVA block from the case.

2. Use tweezers to peel off the red strip label, exposing adhesive.

3. Press adhesive onto the target surface to collect shed cells.

4. Place EVA block back into the protective case and close it.

5. Fill in sample information on the case label.

6. In the lab, remove adhesive film with tweezers, place into a centrifuge tube, and proceed with DNA extraction.

Application Range:
Used in forensic scene investigation, laboratory DNA analysis, and trace cell collection from both smooth and irregular surfaces.
