Mayer’s Reagent - General screening test for controlled substances. Designed as the starting point for sequential testing. If you have a totally unknown substance (tablet, capsule, powder, or chunk), the Mayer’s reagent will direct you toward your next field test.

Marquis Reagent - Presumptive test for MDMA (Ecstasy), Amphetamine type compounds (Amphetamines and Methamphetamine), and for Opium Alkaloids (Heroin and Morphine). To differentiate between Amphetamines and Methamphetamine use the Methamphetamine Reagent (Test 923). To confirm all Heroin (White, Brown or Black tar) use the Mecke’s Reagent (Test 924).

Cocaine Salts & Base Reagent - Presumptive test designed to identify Cocaine HC1, Freebase, or Crack. The pouch configuration must develop three positive reactions: (1) Blue presence, (2) Pink solution, (3) Pink over Blue layering. The tube configuration will develop a Blue solution after breakage of each ampoule with a sticky Blue residue adhering to the side of the tube.

Dille-Koppanyi Reagent - Presumptive test designed to identify a Barbiturate in either a tablet or capsule form. To test tablets, reduce the substance to a powder form. For capsules, open the capsule and remove a small amount of the powder. Place a small amount in the field test. A Lavender color will develop in the presence of Barbiturates.

Mandelin Reagent - Presumptive test designed to identify Methadone. Place a small amount of the substance into the test. Upon breaking and agitating the test, a Dark Blue will develop in the presence of Methadone. In the past, agencies have used this test to confirm the presence of Amphetamine-type compounds. Please use the Methamphetamine Reagent (Test 923) instead.

Ehrlich’s Modified Reagent - Presumptive test designed to identify lysergic acid diethylamide or LSD. Due to the dangerous nature of LSD, take every precaution not to touch or absorb this substance into your system. Upon breakage of the 2nd ampoule a Purple color will develop and after breakage and agitation of the 3rd ampoule (pouch only) the color will deepen. We recommend nitrile gloves for handling LSD.

Duquenois-Levine Reagent (Pouch) - Presumptive test designed to identify the presence of THC in Marijuana, Hashish or Hash Oil. Break the 1st ampoule and agitate for 60 seconds. Upon breakage of the 2nd ampoule a Blue/Violet color will develop. Break the 3rd ampoule and agitate. A layering will occur. The lower layer MUST be Purple for a positive test.

KN Reagent (Fast Blue B Salts) - Presumptive test designed to identify the presence of THC in Marijuana, Hashish, or Hash Oil. It is also designed to react with the green leaf material of fresh Marijuana. Upon breakage of the 2nd ampoule, a layering will occur and the lower layer must be a Tomato Red color for a positive test.

For Acid Contained Kits.

PCP/Methaqualone Reagent - Presumptive test designed to identify the presence of Phencyclidine (PCP) and Methaqualone. Upon breakage and agitation of the first ampoule, a Pink color will develop. After breakage and agitation of the 2nd ampoule, a brilliant Blue will develop in the presence of PCP or Methaqualone. We recommend the use of nitrile gloves for handling all PCP.

Opiates Reagent - Presumptive test designed to identify the presence of all forms of Heroin (White, Brown, and Black tar). To differentiate between Heroin and Codeine, Heroin will appear as a Purple color following the breakage and agitation of the 2nd ampoule; Codeine will develop a Green color. Oxycodone will develop a Yellow color upon breakage and agitation of the 2nd ampoule.

Sodium Nitroprusside Reagent - Presumptive test designed to identify the presence of Methamphetamine and MDMA (Ecstasy). Upon breakage of all the ampoules and agitation, a Dark Blue color confirms the presence of a secondary amine (Methamphetamine or Ecstasy). You can differentiate these substances by using the Marquis Reagent (Test 902) in conjunction with the Sodium Nitroprusside Reagent (Test 923).

Mecke’s Modified Reagent - Presumptive test designed to identify the presence of all forms of Heroin (White, Brown, and Black tar). Break and agitate the first ampoule for 30 seconds. A Green color will slowly develop as you agitate the test after breakage of the 2nd ampoule.

Valium^®/Diazepam Reagent - Presumptive test designed to identify the presence of Valium^®, Diazepam, Rohypnol^® (Roofies), and Ketamine. After breakage and agitation of the two ampoules, a pale Lavender color will develop in the presence of Valium^®, Diazepam, and Rohypnol^®. A darker Lavender color will develop after the 2nd ampoule in the presence of Ketamine.

Talwin^®/Pentazocine Reagent - Presumptive test designed to identify the presence of Pentazocine. Pentazocine is the chemical name for Talwin^®. Upon breakage of the 2nd ampoule, a bright Blue will appear instantly in the presence of Pentazocine.

Ephedrine Reagent - Presumptive test designed to identify the presence of Ephedrine and Pseudoepehdrine. After breakage and agitation of the two ampoules, a Blue/Violet color will develop in the presence of Ephedrine or Pseudoephedrine.

Presumptive test designed to identify the presence of GHB in liquids. Open pouch, then using the pipettes provided, add two drops of the liquid to the pouch and break the ampoule. If GHB is present, a Green color will develop.
