HEROIN (Opioids) Dual Reagent Test Kit (2 tests)

Instructions

NOTE: Dual Heroin Test Kit can only test the PRESENCE, not PURITY or QUANTITY of a specific substance. Always test under a strong light and using the smallest possible sample. Never open more than 1 bottle at once, if you make a mistake you might contaminate the reagents and spoil them. If a few reactions are happening at once, only the darkest one of them will be visible.

How can I test heroin (opioids)?

BEFORE using a heroin test kit

• It’s RECOMMENDED to record the reaction to compare later

STEP ONE for testing heroin powder / crystal

• Take and finely crush a small piece, no bigger than a head of a needle – like this •.
• Put it on a suitable testing plate, preferably a spot test plate or the bottom/underside of a ceramic mug (example). *If using single-use vials insert the sample and observe, as the reagent is already within.
• Add one (or two) drops of Marquis reagent test (or other supplied) on the sample and wait for the results.
• Check reagent test results with instructions.

How to use a heroin test kit?

• Check test results with Marquis test kit: if testing heroin there should be a reddish violet color change reaction.
• Check test results with Froehde test kit: if testing heroin there should be a purple color change reaction.

AFTER using a heroin test kit

• OPTIONAL: Pour baking soda over a finished reaction to neutralize used reagents.
• Wash testing surface under running water.

FAQ

• Fizzing. Any synthetic drug in a form of salt will bubble with most reagent tests, which are strong acids. If you see only fizzing instead of color change, that can indicate presence of a new psychoactive substance.
• Speed of the reaction does not indicate quantity nor purity. However, if you are having trouble interpreting your result try using a bigger sample or crushing it better before testing.
• How many tests can you get from one test kit? A multiple-use test kit lasts up to 100 (5 ml) or 200 (10 ml) tests. Each drop equals one test. A single use-test kit contains 2 disposable ampoules (2 tests). One fentanyl test strip is good for 1 test.

How to check if reagent for testing heroin works?

• Test any substance and compare color reactions with instructions. It’s easiest to use aspirin – Marquis reagent reacts to it with a slow pink color change.
• Keep a sample to compare later in case of doubt. If control sample reacts fine, it means the reagent still works.
