I tested some pills and some mdma using Marquis, Froehde and Mecke. On the pill, no reaction on any of them. On the mdma, I had a perfect reaction from Mecke but no reaction from the other two. I’m guessing the pills are dud but what about the mdma? 31. August 2021

Please can you email photos of the test results


how can I safely dispose of excess/expired reagents? 1. August 2021

Wear gloves. Submerge the open bottle in a bucket of cold water and allow to sit for 5 minutes. While still under water, empty the bottle. Pour the water down the drain.


How long do they last when stored in the fridge? 16. April 2021

About 12 months, if the lid is properly secured. Anything that prevents an airtight seal will rapidly accelerate degradation. The tests last about 6 months at room temperature.


Do the kits go off outside the fridge? I plan to carry them in my luggage while I go travelling across europe. 6. January 2020

The shelf life varies for each one and even then it’s affected by humidity, temperature and oxygen exposure. Our 18*C tests reveal

  • Froehde – over 18 months,
  • Ehrlich – around 1 year,
  • Liebermann – just under 1 year,
  • Marquis – 6-9 months,
  • Mecke – 5-7 months,
  • Mandelin – 5-7 months,


What happens if a sample contains multiple drugs? 14. August 2017

It will produce a mixture of the colours – a lot like mixing two colours of paint. If you have a powder or crystalline substance with two different looking types of crystal, try to separate them and test them individually.


Can I send you a photo of my test result for clarification? 30. August 2016

Definitely! We love talking about testing, please email admin at reagent-tests.uk.
