The EZ Test White enables analysis of a suspect powder to check for Cocaine.
Once the chemicals in the kit are mixed together and a small sample added, the solution will change colour signifying a positive reaction. This can then be compared to the colour chart included with the kit. EZ Test White is very insensitive to the usual substitutes such as Mannitol, so will not give an incorrect positive reading, and will also not react to any other substance from the family of cocaine (Lidocaine, Benzocaine, procaine, etc.). The kit can be used for one single test.
The stronger the resulting reaction, indicates a sample contains a higher percentage of Cocaine.
Step 1: First, fill the red field on the instruction leaflet with some finely ground sample (this is approx. 10 milligrams).
Step 2: Add the contents of both tubes to the bottle of liquid which will result in a greenish upper layer forming.
Step 3: Next add the sample to the bottle, close the lid and shake for 2 seconds.
Step 4: A colour change in the lower layer might take place if there is a positive reaction to the sample. Compare this to the colour chart on the leaflet included in the test. The darker it becomes, the more cocaine is present. If the colour change is still transparent and shows a light to medium brown colour, the sample has a high quantity of adulterants.
