2. How to perform a substance test?
Mind-altering substances are prevalent throughout today's
society. This leads to the continuous development of tests that
are trying to keep up with the drugs market pace. When it comes
to drug tests, there are several categories available, depending
on your requirement. Examples include the substance used, the
amount consumed or the time-frame of consumption.

3. How to perform a substance test?
Other frequently used categories of tests are substance tests.
Such tests confirm or disprove the presence of a suspected
substance. Instead of testing biological samples, presumptive
substance tests only work with a substance that is suspected of
being a narcotic. To explain the steps of performing such tests,
we will take as an example a cocaine substance test from our
product range.

1. Check the ampoules.
If any dark-coloured grains can be seen,
the ampoules cannot be used.

6. 2. Knock the unopened ampoule several times against a hard
surface.
By doing this, particles which may be sticking to the inside of the
ampoule wall will fall to the bottom.

Ensure that the powdery reagent contained in the cap does not
fall out.

8. 4. Open the ampoule.
This can be done as follows: Firmly hold the ampoule at the
bottom in one hand. Take the ampoule tip between the index
finger and thumb of the other hand and, using lateral pressure,
snap it off at the predetermined breaking point.

9. 5. Transfer a small quantity of the sample into the ampoule.
You can use for example the enclosed spatula from the package.
Whilst transferring the sample make sure to hold the ampule in
an upright position, so that the substance falls to the bottom of
the ampoule.

10. 6. Transfer the substance contained in the sealing cap into the
ampoule.
Holding the ampoule in an almost horizontal position, bring the
sealing cap containing the reagent carefully to the opening of the
ampoule, tipping the reagent into the ampoule.

11. 7. Allow the sample and the reagents to mix.
This can be done by tapping the ampoule with your finger or by
repeated stirring with the spatula. After completing the test, the
ampoule must be sealed.

12. 8. Interpret the results according to the instructions that
accompany the test.
All colour changes begin within a few seconds. If the relevant
bases are present, the colour changes take longer. In all cases,
the colour will be fully developed after a maximum of one
minute.

13. 9. Disposal.
It is recommended to seal the used ampoules with the sealing
caps, collect them in their in their original packaging or in plastic
containers and dispose of in accordance with the current waste
disposal regulations in the country of use.

14. After completing the test and interpreting the result, keep in mind that
a variety of medicines might lead to similar or different colours.
Every positive result has therefore to be confirmed by a laboratory
test.
