GET ALL TOOLS

Get your sample, reagent (4-AP Reagent) ampoule, a sharp tool / scoop and paper towels.

PREPARE SAMPLE, ABOUT THIS BIG -> ●   

A bigger sample can cause a stronger reaction. You need a new sample for each test.

ADD PREPARED SAMPLE TO REAGENT

Break open glass ampoule by gently pushing bottom of plastic cap outwards with your thumb pointing down. Do not crush the glass ampoule, after a few soft pushes and 10-20 seconds of trying the ampoule head will snap off without any effort. Using included plastic spatula add prepared small (●) sample inside opened plastic tube. Add liquids from both glass ampoules to the plastic tube, mix for at least 30 seconds.

OBSERVE AFTER 3 MINUTES

Disregard any color change after 5 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.

Close used items inside plastic tube and dispose safely.
