GET ALL TOOLS
First, prepare a clean white testing surface – ceramic or glass is the best, e.g. bottom of a mug or a plate. Get your sample, reagents, a sharp tool / scoop and 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 sample can cause a stronger reaction. You need a new sample for each test.
ADD ONE* DROP (OR PILE) OF REAGENT
Shake bottles hard before use, then tap firmly to shake down any reagent stuck in cap. Do not let a bottle touch sample or you will ruin the rest of the reagent. Use just enough reagent to cover a sample. If using crystals avoid air pockets by flattening crystals onto sample using a clean tool. *Do not combine reagents except for „A” and „B” bottles.
OBSERVE FOR UP TO 3 MINUTES*
Disregard any color change after 3 minutes. Do not overinterpret your results, consider that color change reaction is always fastest and most vivid in the part where biggest surface of reagent touches sample, compared to its edges. Over time reaction will degrade due to air contact. Take photos.
COMPARE RESULTS
Compare color change with instructions. Reagents can indicate PRESENCE, but not QUANTITY. Adulterants can be detected with reagents only if they cause a darker color change than the expected substance. To detect all ingredients and estimate their amount pair reagents with a TLC purity test kit.
Clean used reagent tools / testing surface with lots of running water and detergent, avoid contamination.

[REWARDED REVIEW] 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.
