TA FRAM ALLA VERKTYG
Förbered först en ren, vit testyta: keramik eller glas är bäst, till exempel undersidan av en mugg eller en tallrik. Ta fram ditt prov, reagensen, ett vasst verktyg eller en skopa och hushållspapper.
FÖRBERED ETT PROV, UNGEFÄR SÅ HÄR STORT -> ●
Om du testar ett piller, pulver eller en kristall, krossa det fint. Om du testar en blotter eller en geltablett, klipp av 1/8 (ett hörn). Om du testar en vätska, låt en droppe torka på papper eller en ren keramisk yta. Ett större prov kan ge en starkare reaktion. Du behöver ett nytt prov för varje test.
TILLSÄTT EN* DROPPE (ELLER LITEN HÖG) REAGENS
Skaka flaskorna ordentligt före användning och knacka sedan bestämt så att reagens som fastnat i locket rinner ner. Låt aldrig flaskan röra vid provet, då förstör du resten av reagenset. Använd precis så mycket reagens att provet täcks. Om du använder kristaller, undvik luftfickor genom att trycka ut kristallerna över provet med ett rent verktyg. *Blanda inte reagens, utom flaskorna ”A” och ”B”.
FÖLJ REAKTIONEN I UPP TILL 2 MINUTER*
Bortse från färgförändringar efter 2 minuter. Övertolka inte resultatet: färgreaktionen är alltid snabbast och tydligast där reagenset har störst kontaktyta med provet, jämfört med kanterna. Med tiden försvagas reaktionen av kontakten med luft. Ta foton. *Om du testar en blotter eller en geltablett med Ehrlich eller Hofmann, observera reaktionen i upp till 60 minuter.
JÄMFÖR RESULTATEN
Jämför färgförändringen med instruktionerna. Reagens kan indikera NÄRVARO, men inte MÄNGD. Utblandningsmedel kan upptäckas med reagens bara om de ger en mörkare färgförändring än den förväntade substansen. För att hitta alla beståndsdelar och uppskatta deras mängd kombinerar du reagenserna med ett TLC-testkit för renhet.
Rengör använda verktyg och testytan med mycket rinnande vatten och diskmedel för att undvika kontaminering.

Great collection of regents that provides a very broad number of results, but why, please tell me, why would you go with crystalline base for the most useful ones, the reaction is very faint , it is leaking everywhere because the bottlecaps get clogged by small crystalline bits making them difficult to seal, it also really messy to handle, and to get the right amount out of the tiny hole.
I will have to get a replacement set of erlich froehde mecke marquise and Liebermann in liquid form, apart from that, the rest of the kit is good

The change from liquid acid based reagents to solid has sevaral reasons: most importantly liquid sulfuric acid in concentrations above 15% has been illegal for individuals in Europe for several years now, but also the new formulas have significantly extended shelf life (years even in room temperature) and are much less prone to spills and burns.
The issues you described are not normal and suggest you are not using the reagents according to instructions. Crystalline reagents are easy to use, but require a minute or two of getting used to, before first use we encourage you to both read the booklet carefully and watch the short how-to videos we have prepared. 1) Reactions are absolutely as strong as with liquid formulas, if reagents are stored properly and shaken before use. 2) You are supposed to take a few seconds to clean bottle neck and cap after use; as shown on how-to videos it is also helpful to firmly tap the bottles to shake off any crystals from cap into the bottle. 3) As also shown on videos, even simply tapping side of a bottle is perfeclty fine for pouring reagent out, you can also use a plastic tool to apply small amounts if you wish.
If you are still having any issues please reach out to us direclty either via contact form, e-mail, Signal, Telegram or WhatsApp.

huge satisfaction. My friends and I have already tested several substances and thanks to this we have found out which suppliers are trustworthy and which are not. I immediately bought a second set which is located in the pub where we normally meet (the staff is very helpful and wants to do a test once in a while for safekeeping) so that I don’t have to carry it with me all the time.
I thank the entire Protest team for this set and I wish them a lot of success. You are doing a very useful and invaluable job. I wish you a lot of success. Whenever someone asks me for a test I will send them to you immediately.
In short:
Test: 5/5
Shipping: 5/5 (Czech Republic 2 days)
Functionality: 5/5
Price: 5/5
The Protest team and their perfect idea and their determination to continue: 5/5
Total 20/5!
If you are still hesitating whether it is worth it and whether it is worth it at all, remember that you only need a very small amount and you can have long-term consequences.
Don’t take chances with absences!
It’s always better to test it!

Top Preis Leistung
Für den Preis macht man hiermit nichts falsch, Handhabung auch mega einfach.
Sollte zum Equipment jedes Forschers gehören finde ich.

Easy to use without a doubt.
When first getting a test kit i thought that it would be complicated and need some practice before knowing how to use it. However this was not the case. Right after receiving it instructions were clear as day.
1. Look up the substance on this website in the results section.
2. Pick out the reagents which correspond to the substance you wish to test.
3. Test the substance. (There are even some videos showing you how its done)
Its really simple, and makes use of substances way more safe as you have to know what goes into your body. Otherwise you would be betting your life in exchange for a high.

Sehr einfach zu benutzen – das hatte ich nicht erwartet, ich dachte es wird total kompliziert.
Ist aber gut machbar und verständlich! Hervorragende Sache.
Der Farbabgleich ist noch nicht perfekt, weil die Farbskalen sehr klein sind und auf der Rückseite dieses riesigen Blattes, das man dann immer anders falten muss. Ein paar Streifen beizulegen wäre viel schöner gewesen.
Der Spatel – es ist nur einer, und er hat zwei Enden. Man braucht für manche Tests aber mehr. Wie denken die Macher sich das? Soll man ihn zwischendruch auswaschen gehen? Das ist unpraktisch. Da sollte man vorsorgen und vielleicht ein paar eigene Mini-Spatel bereithalten.

Thank you for your feedback! Regarding plastic spatulas – they are not required to use reagents, personally we prefer to simply pour out crystals out of a bottle by tapping it repeatedly, and use the spatula for samples only. We are working on implementing a recommendation system on our website to suggest optionally getting multiply plastic spatulas. Regarding big size of the booklet – the huge charts are only meant to show the risk of false positives when using any reagent individually. For easy browsing please use the app at https://protestkit.eu/results. We will introduce this suggestion in the nesxt print by the end of this month. Thanks again!

Works pretty well; I preferred the 100% fluid version, but EU regulations made those illegal.
Useful advice:
– Make yourself familiar with the process at home using e.g. Aspirin. There are plenty of substances in any home to try out the process before taking the kit to the field.
– Use a clean spatula for each reagent/subtance combination or you’ll contaimate the reagents really quickly.
– Have plenty of water handy to rinse the porcelain tray. Rub it dry with cloth or paper towels, then repeat. (Don’t start with paper towels, some tests are pretty corrosive.)
– If you have some Sodium carbonate handy, use that to neutralize the reagents before rinsing. Your sink and nature will thank you.

This test kit has everything you need in it to test your substances, it took me two tries to get a positive, but that was 100% my lack of experience using the test kit. I found very clear instructions in the video and was able to get a positive result, the second set up. Thank you for making it so easy for people to test the substances.
