Precision Forensic Testing has developed a Gun Shot Residue (Powder Pattern Analysis) lecture and laboratory which uses the same techniques used in processing evidence in crime laboratories. 

In addition to learning the correct technique, students learn the methods and science behind developing gunshot residue patterns on fabric samples which have been shot from an unknown distance.  In the laboratory exercise, students will use known standards (included with the kit) to determine the distance of the firearm from the fabric.

The lecture includes a case study to further emphasize the importance of performing Gun Shot Residue analysis.  As with other Power Points produced by PFT, teacher notes are included to assist in lecturing.

The chemicals necessary to perform GSR analysis are included with the kit*.  The amount of chemicals included are sufficient to perform five laboratory sessions (20 sheets each session).  Additional chemicals are available to refill your kit.

*Standard laboratory chemicals such as Methanol and Acetic Acid are not included.
*MSDS are included with the kits.

Each kit includes:

• 20 fabric samples for performing laboratory exercise*
• 2 mist spray bottles for chemical application
• Lead standard
• Four chemicals essential to performing GSR Analysis
• Power Point Presentation for teaching Gun Shot Residue Analysis
• Power Point Presentation for teaching Lab Techniques
• Teacher Notes
• Lab printout with worksheets

*additional fabric samples available for purchase separately.
