Would storing your reagents in the freezer prolong the shelf life if you use them very infrequently? 29. April 2017

We don’t recommend freezing because the reagents can freeze and precipitate (un-dissolve) parts of the mixture.

Froehde and ehrlich aren’t susceptible to this and colder temperatures will slow down the reactions that cause them to degrade. Ensure they are in a sealed bag and are allowed to warm fully to room temperature before opening the bag.

Why can’t Liebermann or Mandelin tests be used as stand alone tests for MDMA? They appear to detect the most substances 20. April 2017

There are no standalone tests for any drug because any test could have two compounds which react the same way. Using multiple tests allows us to reduce the probability of this. If one test has a 5% chance of two drugs with the same colour, then two tests has a 0.25% chance and three tests has a 0.01% chance. Really the numbers are a bit different because the colours aren’t random, so we recommend three as the minimum.

Do these kits detect substances like fentanyl? I don’t know how likely it is for mdma to be cut with it, but should I use a fentanyl test as well? 17. March 2017

If you are trying to detect a small amount of fentanyl added to other drugs then you will need to use our fentanyl strips. Reagent tests can detect pure fentanyl sold in place of other drugs.

In the MDMA kits, do you need to test the pill or powder with all three Reagents? Or can can you use different ones for different times 24. January 2017

It is strongly recommended to use more than one different reagent per sample as it gives the best chance of detecting something unexpected.

For example, a cocaine sample cut with paracetamol would show no reaction with the marquis reagent, but an obvious green result with mandelin.

Do these come with pipettes? 18. January 2017

The bottles have a built in dropping system so do not need pipettes

Is it necessary to keep the bottles in the fridge? How will this affect the reliability / shelf life of the products? 15. January 2017

The reliability will be the same but the reagents won’t last quite as long. In our experience they will usually still get pretty close to a year but even at the best of times the shelf life varies so it’s hard to give a specific number. We find the froehde reagent lasts more than a year even when it is not refrigerated and the same for the ehrlich reagent – the reaction just takes a little longer.

Can the reagents be used straight out the fridge or have they got to be room temperature ? 10. January 2017

Allowing the reagents to come to room temperature prevents condensation on the inside of the bottle and means the reaction occurs a little quicker. It’s not essential but it is recommended to allow you to get the full shelf life.

Are you allowed to take the reagents on an aeroplane? 26. December 2016

They are legal but you would need to check with your airline regulations. Make sure that the lid is on very tight and each bottle is individually wrapped in a leakproof container.

What is the initial but very brief green tinge which then proceeds to a very dark violet/black a sign of when testing a supposed Ecstasy (MDMA) pill? 20. December 2016

This is just a normal reaction of MDMA – it isn’t always possible to see but it occurs even with very pure MDMA.

If I am testing ecstasy, should I be expecting the colour associated to MDMA (blue > violet > black) or will it be a mixture of colours as ecstasy does not always directly mean pure mdma? 12. December 2016

In the modern “ecstasy” market a large majority of pills contain only MDMA. If you believe they contain something else then generally it is better to throw them away rather than try to guess how the extra components will affect the risk. Some people get around this issue by buying crystal MDMA which should never have other substances added.

How discreet is purchasing from this site on a bank statement? 17. November 2016

It depends on your payment method but none of the methods we use include the full name or any product details

If i buy a kit and don’t use it will it last longer than ~1 year? I mean is it vaccuum sealed or something? Or is shelf-life starting when i place my order? U are sweet guys/girls 🙂 Love 20. October 2016

Thank you for the kind comments 🙂 The less you open the reagents, the longer they will last. The froehde reagent lasts absolutely ages, often over a year, whereas the mecke and marquis reagents will only last a year even in an inert atmosphere because they spontaneously decay. If you want a long shelf-life selection I recommend froehde, mandelin and ehrlich but really for peace of mind I think it’s better to just spend the £15 annually.

I was wondering what you mean when you say putting a quarter of a blotter into 1ml vodka. What does this do exactly? 12. October 2016

Most reagents react with the blotter paper itself, so the LSD must be dissolved into liquid first which makes only the colour change from the LSD apparent. The ehrlich reagent doesn’t react with blotter so it can be applied directly. Drop us an email if this still isn’t clear, we’ll be happy to discuss it 🙂

Each different chemical has a different colour, however what would happen if my sample has a mixture of two or more chemicals? Will it produce a different colour entirely? 6. October 2016

It will produce a mixture of the colours – a lot like mixing two colours of paint.

Can I use the 3 different reagents on a single sample of MDMA by washing it after each test or do I need to keep using sample. 22. September 2016

The MDMA is destroyed by the test so you would need to use three crumbs for three tests. This is about 1/100th of a gram for all three

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.

Is there any value in observing what happens after 30-60 seconds? 22. June 2016

The ehrlich reagent may be slow enough to need observing over 2 minutes but none of the other reagents are – 60 secs is plenty.

Are reagent tests legal? 1. June 2016

We are not aware of any countries in which reagent tests are illegal. The reagents are used in laboratories for testing other common compounds so banning them would be impractical.

How do you test LSD which is already on a blotter tab? 25. April 2016

The ehrlich reagent can be applied directly to blotter.

Other reagents need the blotter to be submerged in alcohol (rubbing alcohol works fine) first.

How can I cancel an order? 24. March 2016

Please email us, we will be happy to help.
