The modified version of the Cobalt Thiocyanate is a more specific field test for Cocaine and will distinguish between Cocaine HCl and Cocaine Base. Cocaine HCl will develop a Blue solution in the 1st ampoule as well as a sticky Blue residue adhering to the inside of the tube. The 2nd ampoule will remain Blue. No base caines (procaine;dibucaine;tetracine) will develop the sticky blue residue in the 1st ampoule. Cocaine Base will not dissolve in the 1st ampoule and will develop a Pink solution with Blue adhering to the particles of Cocaine Base introduced to the tube. 10 tests/box.
Like all our NARK narcotic field tests, the Modified 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.
