NARK II Ehrlichs Modified Reagent (LSD)


For Sale to Law Enforcement Only!

Due to the potential for absorption of LSD when handling, take precautions by using nitrile gloves and wash hands thoroughly after handling. Presumptive test designed to indicate the presence of d-lysergic acid diethylamide (LSD). Introduce LSD powder directly into the test but moisten an absorbent material with liquid LSD, air dry for 45 seconds, then place in the pouch for testing. Like all our NARK II narcotic field tests, the Ehrlich’s Modified Reagent is meant for presumptive field drug testing. 10 tests/box.

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.
