Not a specific field test for Cocaine only. This reagent will identify Cocaine; Procaine and Tetracaine with Blue flakes in the 1st ampoule. These same Blue flakes will slightly dissolve after breakage and agitation of the 2nd ampoule. The #NAR10013 Modified Cobalt Thiocyanate Reagent is a more specific test for Cocaine. 10 tests/box.

Like all our NARK narcotic field tests, the Cobalt-Thiocyanate Reagent is meant for presumptive field drug testing.

NOTE: ALL TEST RESULTS MUST BE CONFIRMED BY AN APPROVED ANALYTICAL LABORATORY! The results of this test are merely presumptive. NARK® only tests for the possible presence of certain chemical compounds. Reactions may occur with, and such compounds can be found in, both legal and illegal products. This test must be administered following its specific instructions and may be used in conjunction with other reagents in the NARK® II Sequential Testing System.
