Full Product Description:
Reagent Test Kit - £6.95 Zimmermann reagent.
We use Enhanced ultra-discreet packaging for all our deliveries
Zimmermann Reagent (Reagent A (WHITE) + Reagent B (WHITE)) ~2.5mL each
2 Reagent dropper bottles
1 small glass test tubes (mix Reagent A + Reagent B) plus 2 stand mechanisms
Note: use the provided test-tube. NEVER pull the Blue lid/cap/stoppers out of the test tubes or they may break. Use a slight unscrewing twisting motion whilst lifting vertically and they will come out easily if they have been fully inserted.
It is a two part test. Reagent A and Reagent B, and as there are two reagents that require proper mixing this is better performed using a test-tube.
Add one, or 2, drops of each reagent. Swirl gently a couple of times (lid on for safety) to assist in mixing the reagents & note the initial colour of the resultant liquid (chalky white). Then add the test substance (~ 10 salt sized grains) to the test-tube and swirl again applying a little heat (place test tube in warm/hot water for about 10 seconds or in steam (lid on with finger gently over top of lid) for about 2 seconds). If you do not warm/heat the test tube the reaction will take several minutes and will not be as distinct especially if the reagents are stored in a fridge prior to use.
The reagent works by forming a reddish-purple Meisenheimer complex at C3 for diazepines with a carbonyl at C2 and an alkyl group at N1. Without these groups it is not possible to form the methylene compound which reacts with dinitrobenzene but triazolo compounds may react.
The rapid development of either a red–purple/violet or pink colour indicates the presence of benzodiazepines in the substrate.
Expected colour responses (Benzos) results:
Zimmerman’s reagent produces violet/purple colours with keto-benzodiazepine derivatives such as diazepam (Valium), rohypnol (Flunitrazepam) fludiazepam (Erispan ) and flurazepam (Dalmane), Benzyl-methyl ketone (P2P/phenylacetone), Acetone, Methcathione, Oxycodone.
