Each kit will do up to 50 tests and you only need a tiny sample. The tests are two that are utilized by forensic police.
The Marquis E-Testing Kit is a spot test reagent used by forensic police to make preliminary identifications on pills and powders. In chemistry circles, it is know as Marquis reagent, and consists mostly of concentrated sulphuric acid and formaldehyde.
The Mandelin E-Testing Kit is another spot test reagent used by forensic police to help identify pills and powders. It mostly consists of sulphuric acid and a chemical that reacts specifically with many more illicit substances than Marquis reagent.
