This is NOT a primary test. Nitric Acid is designed to differentiate between Heroin/Morphine. Agencies looking to confirm the presence of Heroin should use the specific test #NARK20011 Mecke’s Modified Reagent. 10 tests/box.
Like all our NARK II narcotic field tests, the Nitric Acid 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.
