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 blotter or gel tab cut off 1/8th (a corner). 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 2 MINUTES*
Disregard any color change after 2 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. *If testing a blotter or gel tab using Ehrlich or Hofmann observe reaction for up to 60 minutes.
COMPARE RESULTS
Compare color change with instructions. Reagents can indicate PRESENCE, but not PURITY or 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.

The test kit succesfuly helped me identify all four suspected substances I tested, with textbook results. The packaging is discrete and the contents of high quality. Would recommend without giving it a second thought

Rly good kit to test your staff. This made my suspicions clear about powders – its not what they say it is. And once we know it, and we have proof, we can advertise it an hopefully incrase powders quality on street.

The kit works as intended, it’s somewhat sad to see the change from liquid to solid reagents as its much more difficult to handle and apply, however that’s not the providers fault and they have to conform to EU regulations. However, it would be nice if organizations had the option to purchase the liquid versions for their own use. In any case, with this kit you can probably identify most things except the most exotic research chemicals. Protestkit is still our go to supplier for drug-checking reagents.

Thank you for your kind words, we are happy the kit works as intended. As for your concenrns, in our experience crystal reagents are much easier to apply than liquid corrosives, don’t spill or discolor and last way longer, please reach out to us by contact form or email to troubleshoot any difficulties. As for liquid version for organizations / companies, we can provide that upon request via contact form / email.
