– Gun Shot Residue Presumptive Test Kit

Innovating Science chemistry kit is used to determine whether a surface has been exposed to discharged firearm, which is indicated by a two-test process in which a rapid color change verifies the presence of nitrates and lead. For conducting multiple experiments, the kit has materials for 30 tests, including diphenylamine sulfuric acid solution, sodium rhodizonate, lead nitrate, and alcohol swabs. The kit has an instructions and safety data sheet (SDS) packet for product information and handling procedures. The kit is suitable for age 13 and older with adult supervision, and meets the requirements for Department of Transportation (DOT) small quantity exemption 173.4, and conforms to 49 Code of Federal Regulations (CFR) 173.4 for domestic highway or rail transport only.What’s in the Box? (1) diphenylamine sulfuric acid solution (5.0mL) UN1830 (1) sodium rhodizonate (0.025g) (1) lead nitrate 0.05M aqueous solution (5.0mL) (20) alcohol swabs Instructions and safety data sheet (SDS) packetWhenever a bullet is fired, not everything is combusted. The force of the explosion can cause some of the material to be ejected from the gun anywhere that the heat and gas, caused by the firing of the bullet, can escape from the gun. Once expelled from the gun, the material can settle on the shooter’s hands, clothing, hair, or on parts of the crime scene itself.The presumptive gunshot residue test is actually two tests. The first test is the diphenylamine test, which detects the presence of nitrates, which are a common compound used in ammunition.
