Drop Ex





Drop Ex

Drop-Ex Plus is the latest Explosive Detection and Identification Kit. Drop-Ex is actually an extension of the popular DROP-EX Kit and detects the widest possible range of explosive types, due to its ability to detect the additional explosive categories for improvised explosives: Chlorate and Peroxide-based explosives.


Peroxide-based explosives are powerful explosive substances that can be prepared from several over the counter materials. This well–known explosive type is currently in use by terrorist groups. This explosive material is usually known by its abbreviation TATP (Tri Acetone Tri Peroxide).
This system is based on the same reagents in Expray™, but in a dropper bottles, for ease of use during field and laboratory investigation. The first sample can be tested using Drop-Ex 1, 2 and 3. The test for chlorates, bromides and the peroxide based explosives must be a separate test using Drop-Ex A and Drop-Ex B.

Detection Range of the Kits

Drop-Ex # 1 for Group A
(Nitroaromatics) – this type of explosives includes TNT, Tetryl, TNB, DNT, picric acid and its salts.


Drop-Ex # 2 for Group B
(Nitrate esters and nitramines) – this type of explosives includes Dynamite, Nitroglycerine, RDX, C4, PETN, Semtex H, Nitrocellulose and smokeless powder. NOTE: Most plastic types of explosives belong to this group.


Drop-Ex # 3 for Inorganic nitrates – the nitrates based explosives include ANFO (ammonium nitrate-fuel oil), commercial and improvised explosives based on inorganic nitrates, black powder, flash powder, gun powder, potassium nitrate, and ammonium nitrate.


Drop-Ex A for Chlorates and Bromates – this type of explosives includes potassium chlorate and sodium chlorate. Drop-Ex # A is used for detection of chlorates and bromates and can be used by itself.


Drop-Ex B for Peroxide-based explosive compounds – includes TATP (Tri Acetone Tri Peroxide) and HMTD


Drop-Ex # B requires that Drop-Ex # A be used first. If you are not sure what type of explosive you are testing for, you will need two samples.
