NARK Sodium Nitroprusside Reagent (Meth MDMA), tube style

The sodium nitroprusside reagent is designed to color react with the secondary amines present in both Methamphetamine and MDMA (Ecstasy). This presumptive field test will develop an IMMEDIATE (within 2 seconds) Dark Purple or Dark Blue color as a positive reaction after breakage and agitation of the 2nd ampoule. If the color development is an immediate Pink slowly transforming to Lavender, you DO NOT have either Methamphetamine or MDMA. This color reaction suggests you should proceed to the #NAR10002 Marquis Reagent for either Amphetamines or analogs of MDMA (referred to as Letter Drugs). 10 tests/box.
Like all our NARK narcotic field tests, the Sodium Nitroprusside Reagent is meant for presumptive field drug testing.
