Can these kits be used to test liquid drugs e.g lean etc 1. June 2020

No, liquids must be dried. Furthermore, lean is a mixture of chemicals such as sugar and colourings, and this can create an uncertain result.

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,


Are reagent tests illegal in the UK? 13. September 2019

You must have “good reason” to carry these tests in public. “I am on my way home from a party where I was helping people be safe” is an acceptable reason.

Testing kits are not illegal to own. If you ever get in trouble for them please contact us and we may be willing to contribute to legal fees for you.


Is packaging discrete? 8. January 2019

It’s a 25mm white box with nothing but your name and address on it.


My bottle isn’t full up to the top 5. January 2019

We package our 2 mL portions of reagent into 5 mL bottles to ensure more consistent drop rate as the bottle empties. The 2mL of liquid in the bottle will still give between 30-40 tests, as advertised.


How do you dispose of old test kits? 3. March 2018

While wearing gloves and eye protection, start the cold tap running gently and then remove the lid of the reagent bottle and upturn it so that the contents drip into the flowing water. As soon as they are diluted, the risks are very low but it is not safe to drink or wash in the water.


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.
