Tri-Tech Forensics GSR (Gun Shot Residue) Kit, 4 Stubs & 12 Swabs - Case of 10

The Tritech GSR-AA/SEM SBI Kit comes with case of 10. There are basically two types of analysis which can be conducted upon collected residues. The first type of analysis is conducted by scanning electron microscopy (SEM) upon residues which have been collected on sticky metal stubs. The second type of analysis is conducted by atomic absorption (AA) analysis upon residues which have been collected on cotton-tipped swabs. The GSR-AA/SEM is a combination kit. The use of this kit allows your crime laboratory to perform a quick screen using AA and then, if warranted, a more definitive analysis by SEM. Kit Conponents 1 ea.
