Step 1 - The Detection step (done with the First Sampler) :
A  Remove Sampler (1) from the IDenta test unit.
B  Apply Sampler (2) on suspected substance to be tested.
C  Return Sampler to its test unit cradle.
D  Break ampoule in Chamber 1. If no color develops, then break ampoule in Chamber 2 and shake the Test Unit for 2-3 seconds.
E  If color develops, proceed with test unit Step 2 for confirmation!

Step 2 - The Confirmation step (done with the Second Sampler) :
A  Repeat Stages A-B-C in Step 1. Break ampoule in chamber 1.
B  Gently shake Test Unit for a few seconds.
C  If a red-violet coloring developed in Step 1-D, and a purple or purple-brown color develops here - this confirms the presence of Heroin street drugs. If a red-violet coloring develop in Step 1-E and a purple color here, this indicates the presence of Heroine. Wait 2 Minutes.
D  Break ampoule in chamber 2, whether or not color apears - shake gently (For acid neutralization).
E  Break ampoule in chamber 3 - shake gently (for completion of acid neutralization).
This example is given on the Heroine sampler, but the usage of the Cocaine/Crack, Ecstasy/Speed samplers is the same. In the Marijuana/Hashish tester, however, you do not even need to use the STEP 2 Sampler, which makes it even easier to use!
