I have the Mecke Frodhe and Marquis kits will any if these test for Cyclopyrrolones? 6. December 2019

Please email Cyclopyrrolones@reagent-tests.uk, I think this needs a bit more in-depth discussion. From Guy.

What is the difference between Ehrlich and Hofmann tests and why are they both sold together, if I was to test Lsd for example, wouldn’t I only need to use one of them? Or do they both go together? 5. December 2019

The Hofmann test is used to distinguish different compounds that are closely related to LSD. These compounds are rare, expensive and have the same risks as LSD. The hofmann reagent can’t detect the presence of DOC and its relatives or NBOMe and its relatives so we believe that it is better to test with marquis or froehde as a higher priority.

If I was to test blotter Paper what are the most common chemical of it didn’t contain LSD ? And would it show those chemicals up ? 2. December 2019

If a blotter sold as LSD does not contain LSD you should put it in the bin. Either your dealer is a liar, or they do not know what they are selling. Both situations could be fatal. Using the LSD testing multipack it would be possible to find out more about the substance but you should still not take it if the result is not what you expected.

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.

What kit is best to test ketamine? 1. August 2019

The Liebermann reagent is the only one that gives a truly consistent reaction with ketamine but it is a faint yellow. The mandelin reagent usually goes orange with ketamine, sometimes it does not change though. The marquis reagent gives no colour change with ketamine but does react with some impostor substances like 3-MeO-PCP.

The cocaine testing multipack we offer contains all three of these.

How do I know if the bottles are inaccurate/out of date? 28. July 2019

You can test your reagents using common drugs like paracetamol, ibuprofen and aspirin. Check out the reaction results & instructions page for more information.

Can i take this on the plane? 3. June 2019

You would have to check the regulations of your airline but if you do, it is best to put them in checked luggage and make sure that the lid is on tightly and they are individually bagged as they will damage your luggage if they leak (due to the reduced pressure in the hold). They can be safely transported individually bagged in hand luggage with your other liquids, again airline regulations permitting.

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.
