Sirchie NARK Duquenois Reagent (Marijuana/Hashish/THC)

Sirchie NARK Duquenois Reagent (Marijuana/Hashish/THC)

The Sirchie NARK Duquenois Reagent (Marijuana/Hashish/THC) is a trusted and efficient presumptive THC test designed to identify the presence of THC in Marijuana. Recognized for its accuracy, this test is the cornerstone for the three ampoule Duquenois-Levine test but stands firmly as an excellent test for THC on its own. The user-friendly test requires agitation of the first ampoule for sixty seconds, during which no color should develop, indicating THC presence. If color develops, it may be a false positive. The third ampoule flashes a fleeting green color before settling on a midrange purple. As with all NARK narcotic field tests, it is designed for presumptive field drug testing and should be used following its specific guidelines. Please note that all test results are presumptive and should be confirmed by an approved analytical laboratory. This test is only sold to Law Enforcement Agencies and Officers.
