forensic field sampler

Forensic Field Sampler

A high purity certified 12.7mm SEM pin stub specimen mount (see 16253, below) with and without an adhesive carbon conductive tab, mounted into the plastic cap of a glass specimen vial (25mm OD x 55mm high). The Forensic Field Sampler has been designed to collect forensic evidence with minimum interference and/or contamination coming from the sampler. Comes in 3 versions: without adhesive carbon tab, with adhesive carbon tab ready to use, and covered carbon tab (plastic cover needs to be removed prior to use). Available with standard 12.7mm SEM pin mount with 8mm pin or short 12.7mm SEM pin mount with 6mm pin (ZEISS/LEO)

Applications for SEM or light microscopy investigation:

  • Gunshot residue (GSR)
  • Fiber collection
  • Particle sampling
  • Glass fragments
  • Paint chips
  • Powder samples

Ideally suited for SEM specimen preparation on the most commonly used SEM pin stub, facilitating easy carbon coating for SEM/EDX investigation.

The Forensic Field Sampler can be safely stored in the glass specimen vial and can be easily shipped since the cap holds the sampler stub in place. Evidence material is held by the adhesive carbon tab.

carbon conductive tabs SEM mounts not included.

PELCO Tabs™ Carbon Conductive Tabs, Double Coated

The simplicity of application and smooth, clean surfaces of PELCO Tabs™ Carbon Conductive Tabs are a significant improvement compared to many of the other common adhesives that have been used in SEM mounting. Both tab sides have a thick conductive adhesive (conductive inner tab is 35µm and the adhesive is 45µm on each side for a total thickness of 125µm [5 mils]) with a liner on both sides, a transparent liner and white liner respectively. They are ready for immediate use. The top protective liner does not have to be removed until the sample is ready to be mounted. This reduces possible contamination. Outgassing is negligible.

Application of the tab to a mount or surface should be done slowly and carefully to maintain surface smoothness.

The conductive adhesive is a carbon filled acrylic, free of solvents. It can be removed from the specimen mount with ethyl acetate, ethanol, isopropanol, alcohols or our 3M™ Adhesive Remover 80924 which is solvent-free. Temperature maximum is 60°C (140°F). High purity carbon tabs may contain very small impurities of Al and Si; see EDX Spectra.
This product may also be used for gunshot residue analysis.
Many laboratories use these tabs for SEM in a large diversity of applications. Refrigeration will increase shelf life but a warm up period of one hour is then required before use.
The PELCO Tabs™ consist of a carbon fiber mat impregnated with carbon filled acrylic adhesive. There is no internal carrier film.

PELCO Image Tabs™, 260µm (10mil) Carbon Conductive Tabs, Double Coated

Back by popular demand, the thicker PELCO Image Tabs™ is a return to the stiff 260µm (10mil) thick smooth conductive tab. Though not as conductive or sticky as the current 10mil PELCO Tabs™, PELCO Image Tabs™ are suitable as a photographic background and are repositionable. This tab is also suitable for Jet Scan applications where the tab must be removed and archived. The PELCO Image Tab's™ surface is less prone to bubbling and cracking when metal coated under vacuum and thus better than the 125µm (5mil) PELCO Tab™ as a photographic background for small particles like pollen and insect parts.

Both sides of the 200µm thick conductive polycarbonate base have 30µm thick conductive adhesive. Total thickness is 260µm with a liner on both sides. Protection for handling, storage and shipping is provided on one side by the transparent liner sheet and on the other side by the white liner cover.

The conductive adhesive is a carbon-filled acrylic, free of solvents. It can be removed from the specimen mount with ethyl acetate, ethanol, isopropanol, alcohols or our 3M™ Adhesive Remover 80924 which is solvent-free. Temperature maximum is 60°C (140°F). Small impurities of Ni, Cu, Si, Sb, S, Na, P and very small impurities of Fe and Mg can be found. Refrigeration will increase shelf life but a warm-up time of 1 hour is then required before use.
