can the testing kit be stored in a freezer? and if yes, does it have a negative effect on the shelf life compared to a fridge? 14. March 2018

Yes, reagent test can be stored in the freezer and this does not affect shelf life so long as they are stored inside an airtight second container and not opened when cold (due to condensation).

How long do kits last without a fridge? 11. March 2018

Depending on storage conditions (high temperature), how often they are opened (high moisture) we would expect them to last for 50-75% of their normal shelf life. The froehde reagent is most resistant to higher temperatures


What test could I use to distinguish between MDMA and MDA/MDE? 6. March 2018

The liebermann reagent can do this but MDA is very rare on european markets

When testing with multiple reagents for PMA and PMMA if there is even a small amount of MDMA in the sample will the black/purple colour that presents for MDMA over ride the paler colours or is the colour quantitative? 6. March 2018

The colour is quantitative, but you are correct to note that PMxA has a paler colour so a 50/50 mix perfectly mixed with MDMA would probably be hard to detect. However, if it was a mix of two types of crystal then you can often see the difference between that and a pure sample.

Do you ship your products to South Africa? 5. March 2018

Yes we do :)

I want to test whats in some supposed xanax tablets. Which kit should I buy? 5. March 2018

Unfortunately benzodiazepines are quite nonreactive and as a result there are almost none that give a colour change with reagents. The main concerns with counterfeit pills is them having a much stronger effect than normal and so this can only be done with lab measurements. The presence of fentanyl can also be a concern, you can dissolve the tablet into vodka and use our Fentanyl Testing Strips to check for this.

How Long does it normally takes to get a things thats backordred ? 5. March 2018

Usually 1-3 weeks

do your kits tets for purity of cocaine? 4. March 2018

No, reagent tests are for detecting impurities rather than detecting purity. This is because purity is affected by cocaine breakdown products, which are remarkably hard to distinguish from cocaine itself outside of a lab.

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.

Is the package plain and discreet? 3. March 2018

Yes, extremely discreet and the only thing on the outside is the address and postage sticker. Please check our shipping info page for more information.

On your shipping page is says the Free Shipping is “typically dispatched the Friday after you placed your order”. Does this mean if I order on a Monday I’m unlikely to receive it the same week? 3. March 2018

Yes, our Free Shipping service is low priority to enable us to offer it for free. It can take 7-10 days to arrive. If you need your order quickly then you will need to select our Express or Next Working Day service.

Can any of the kits detect the presence of fentanyl? 5. February 2018

We have fentanyl testing strips which are designed for detecting trace amounts of fentanyl. The reagents can only alert to samples which are 100% fentanyl.

Can I fly with a test kit? Has anyone run into issues at airport security/airlines? 24. January 2018

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 they are double bagged as they will damage your luggage if they leak (due to the reduced pressure in the hold).

what will the packaging look like and if opened how is the package displayed? 15. January 2018

The packs are sent as plain boxes with your address on them. Inside there is packaging and the items you ordered. You can select the “Stealth Delivery” item from the store if you would like the documentation to be removed.

Where is my delivery 11. January 2018

Please email us for enquiries about specific orders – we cannot publish private information

which test kit is used for ketamine? 23. August 2017

Ketamine itself doesn’t give a colour change with any reagents but cutting agents do – the cocaine testing multipack is actually most suitable for this as some preservatives in vetinary ketamine give a faint orange reaction with the mandelin reagent and a faint yellow with liebermann, which is a helpful identification hint.

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.

Hi, how it will show the purchase on my bank state account? 25. May 2017

The statement note is discreet and cannot be linked to us through google or other search engines (and we’re not going to post it here for exactly that reason!)

Do these come with pipettes? 18. January 2017

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

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.
