The GRA300 is designed for use by Departments that anticipate submitting evidence for Scanning Electron Microscopy (SEM). The GRA Series of kits feature special alloy aluminum mounts that contain no barium, antimony or lead-the most common constituents in cartridge residue. GRA tests are specific and sensitive for collection of gunshot residue using SEM techniques, and are economical and not complex.
GRA300 comes complete with:
1 - Factory sealed, tamper-evident Kit Envelope, 6" x 9"
1 - Instruction Sheet
1 - GRA Information Form
1 - Pair, Disposable Nitrile Gloves
