PREPARA GLI STRUMENTI
First, prepare a clean white testing surface – ceramic or glass is the best, e.g. bottom of a mug or a plate. Get your campione, reagenti, a sharp tool / scoop e paper towels.
PREPARE SAMPLE, ABOUT THIS BIG -> ●
If testing a pill, powder or crystal, crush it finely. If testing a liquid, dry one drop on paper or clean ceramic surface. A bigger campione can cause a stronger reaction. Serve un nuovo campione per ogni test.
ADD ONE* DROP (OR PILE) OF REAGENT
Shake bottles hard before use, then tap firmly to shake down any reagente stuck in cap. Do not let a bottle touch campione or you will ruin the rest of the reagente. Use just enough reagente to cover a campione. If using crystals avoid air pockets by flattening crystals onto campione using a clean tool. *Do not combine reagenti except for „A” e „B” bottles.
OBSERVE FOR UP TO 3 MINUTES*
Disregard any cambiamento di colore after 3 minutes. Do not overinterpret your results, consider that cambiamento di colore reaction is always fastest e most vivid in the part where biggest surface of reagente touches campione, compared to its edges. Nel tempo la reazione si degrada a contatto con l’aria. Scatta delle foto.
COMPARE RESULTS
Compare cambiamento di colore with instructions. I reagenti possono indicare la PRESENZA, ma non la QUANTITÀ. Gli adulteranti possono essere rilevati con i reagenti solo se provocano un cambiamento di colore più scuro della sostanza attesa. To detect all ingredients e estimate their amount pair reagenti with a TLC kit di test di purezza.
Clean used reagente tools / testing surface with lots of running water e detergent, avoid contamination.

Very handy kit.
First use is a bit overwhelming, all the products and all the colors, so prepare for a practise run or 2. Once you’re a bit familiar with it, testing goes quite fast and precise. Keep it safe and test your stuff.
