For Sale to Law Enforcement Only! A presumptive field test designed to identify the semi-synthetic opiates of Heroin (white, brown, and black tar). A distinct Green color will develop after the breakage and agitation of the 2nd ampoule. Due to brown and black tar Heroin having a dark resin, place very small amounts of the substance in the pouch. If the Green color is not easily seen, turn the pouch upside down, allow the dark liquid to drain into the ”new“ bottom of the pouch, and observe the Green color adhering to the glass shards at the ”new“ top of the pouch. 10 tests/box. Like all our NARK II narcotic field tests, the Mecke’s Modified Reagent is meant for presumptive field drug testing.
