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.

This test kit is simply an excellent choice. The selection of reagents guarantees thorough testing and the quantities of them allow for multiple use for up to 2 years. Also, the porcelain plate is of great quality and very convenient. There’s everything required in the package, with the gloves (remember to use them!) and the spatula, so it’s completely ready to use right out of the box. And it all comes in an esthetic box that’s very easy to store. I did not mention that the booklet is very large and informative. You’re not forced to download the app to interpret results or to google anything. Very convenient and you can count on fast delivery as well.

Best reagent company out there right now in my opinion always there on reddit to help answer test results and this is by far the best kit I’ve bought from any company including USA domestic ones which i won’t name

It is the third kit that I buy here and I am always satisfied. The reagents worked fine again, and also the new solid ones are good.
