Forensic Field Sampler & GSR Kits

Forensic Gunshot Residue Field Kits

3-Disc GSR Field Kit. A control disc is added to the two sampling discs to enhance certainty of the analysis. Prod. No. 16256-3.

4-Disc GSR Field Kit. Suitable for sampling palm and back separately on both hands. Prod. No. 16256-4.

5-Disc GSR Field Kit. A control disc is added to the four disc sampling kit to make it compatible with FBI requirements. Prod. No. 16256-5.

A complete line of high quality GSR field sampling kits, containing certified SEM pin stubs with double coated adhesive carbon tabs in plastic tubes. The certified SEM pin stubs have very low amounts of Pb, Sb and Ba, not detectable by SEM/EDX. The caps hold the GSR sample disc for easy and secure GSR collection. The discs are ready to use and the tubes are pre-labeled for the sampling areas. The sturdy transport box is tamper evident sealed.

Each kit comes complete with:

• Certified SEM pin mounts with adhesive carbon discs in pre-labeled tubes
• Pair of powder-free nitrile gloves
• Evidence label
• Chain of custody label on box
• A sturdy cardboard transport box (4-1/2"W x 3-3/4"D x 3"H)
• Tamper evident seal
• Instruction sheet

Forensic Gunshot Residue Lab Kit

16111 & 16111-9

Ten 12.7mm SEM pin mounts in clean, glass storage tubes (25mm OD x 55mm high) held in a compact transport box with labels. GSR Kit is designed to avoid any contamination of the GSR samples. The Forensic Gunshot Residue Lab Kit is available with either standard 12.7mm pin mounts with 8mm pins (16111) or with the shorter 6mm pins (16111-9). Also available as a lab kit without pin mounts and tabs.

Forensic Field Sampler

16250, 16255, 16255-C, 16250-9, 16255-9, 16255-C-9

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.

Numbered Gunshot Residue Sampler

16251

Numbered, certified aluminum mount that has a double-coated adhesive carbon tab applied to hold sample in a clean, glass vial 25mm OD x 55mm high (1" x 2.17"). Packed in a box of 100. Numbers can be chosen as 100 consecutive numbers between 0 and 9999 (greatest numbers). Please inform customer service about the numbering sequence when ordering this product.

PELCO Tabs™ Carbon Conductive Tabs, Double Coated

See PELCO Tabs™ Carbon Conductive Tabs, Double Coated link.

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

product no. 16084-20

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.

"Spectro Tabs Brand", Double Coated

product no. 16084-4 & 16084-5

Construction and thickness is similar to the PELCO Tabs™ Carbon Conductive Tabs above. The EDX Analysis clearly shows a higher purity surface for those applications that require critical composition study; only minor impurities of Al and Si may be found.

Secure-Lock Tamper Resistant Labels

An inexpensive way to safeguard lab shipments, sealed documents or small containers.

16250

An inexpensive way to safeguard lab shipments, sealed documents or small containers.
Once applied these economical, peel-and-stick labels cannot be removed in one piece! Instead, they are formulated to break apart when stressed, giving clear evidence that tampering has occurred.
