Rolling Lifts for Trace Evidence

Description

The Forensic Science Rolling DNA Collector is specially designed for efficient collection of trace epithelial cells from various forensic samples. Its high-adhesion sticky roller effectively picks up shed cells from surfaces, enriching cellular material and improving DNA recovery rates. The collector consists of a roller and handle; after removing the protective film, roll the device over the sample surface. Post-collection, the roller can be removed with tweezers and placed directly into a centrifuge tube for DNA extraction.

Product Features:

1. High Adhesion Roller:

   • Sticky roller surface enhances collection of trace epithelial cells from forensic evidence.

2. Easy-to-Use Design:

   • Roller and handle structure allows smooth rolling across surfaces for efficient sample pickup.

3. Direct DNA Extraction:

   • Collected roller can be placed directly into centrifuge tubes for downstream DNA analysis.

4. Versatile Application:

   • Suitable for oral epithelial cells (cups, cans, masks) and skin cells (sweat prints, gloves, mice, handles, phones, clothing, shoes).

5. Protective Film:

   • Roller comes with removable protective film to prevent contamination prior to use.

Usage Notes:

• Remove protective film by gently pulling toward handle.

• Keep roller perpendicular to surface during collection to prevent dislodging.

• Use tweezers to transfer roller directly into tube for DNA extraction without affecting results.
