This surface drug residue test is based on wet chemistry technology, designed to screen and identify multiple illicit drugs at once. They perform trace detection, as well as bulk identification on most surfaces which makes them a perfect investigative tool for identifying unknown substances. It’s easy and fast to use with visual results in seconds.

This is a multiple drug detection and identification test that helps to specifically identify Cocaine, Crack Cocaine, PCP, and Methaqualone after running the general screening test

The pack contains two separate products, the D4D for screening analysis, and COCA for specific identification. D4D screens for Marijuana, Amphetamine, Mescaline, PCP, Methamphetamine, and Opiate based drugs. When used with the COCA PenTest, it will confirm the presence of Cocaine, Crack Cocaine, PCP, and Methaqualone. The benefits of using both are you can positively identify illicit substances found by the D4D.

The diagram above shows an illicit drug residue test matrix and how different drugs are identified by color. When a suspect substance is found, the process of identifying what it is takes just a few minutes. The kit includes a chemical pen and two analysis papers. The analysis paper is rubbed over the substance and then a few drops of liquid from the chemical pen is applied to the paper, seconds later the paper changes color helping identify what the substance is. This type of Colorimetric test is superior to any other test because the result is instant and color helps to distinguish between different drugs of abuse.
