Surface drug testing kits D4DSurface drug testing kits D4D and C&H

These residue drug testing kits detect and identify narcotic drugs on contact. It’s a low-cost solution for detecting small amounts of narcotics not seen to the human eye. What further distinguishes these kits from other products is that they can perform trace detection as well as bulk identification. A unique investigative tool for narcotic units and task forces, as well as K-9 units and security agencies. You can use these at work, school or home to test almost any surface, including; computer keyboards, credit cards, clothing, liquids and more.

Surface drug testing kits, D4D and C&H are sold as a two-pack, each containing a liquid ampoule and two analysis papers. Together, they can be used to complete four to eight separate tests in all.

How does it work?

Both D4D and C&H use colorimetric technology: A unique non-toxic liquid that when applied to the included analysis paper causes a color reaction. This color change is made possible by a reaction between the liquid, analysis paper, and an unknown narcotic.

Why use two tests?

The D4D test screens many narcotic drugs but does not identify what they are. The C&H test will confirm and recognize many of the drugs found in the D4D analysis. The illustration below shows how the D4D detects many narcotics and how the C&H identifies them.

You can purchase D4D for a first level general screening test, and C&H second level screening separately: D4D and C&H

Instructions for using Surface drug testing kits D4D and C&H:

  1. Wipe the test paper over the suspect area.
  2. Holding the pen test upright, squeeze the plastic tube in the middle to break the ampules inside.
  3. Hold a finger over pen tip and shake for ten seconds to mix chemicals.
  4. Remove the cap while pointing the tube away from you. Point the tube tip down and empty a few drops to the analysis paper to cover the sampling area.
  5. Drip a small drop of liquid onto the analysis paper.
  6. Observe the results of the analysis paper and compare to color charts.

Use D4D first. When you see a color change on the analysis paper, then use the C&H test to identify drugs found. Follow the same process for analysis as the D4D. Wipe the same area with the C&H analysis paper. Observe the colors on the C&H test paper and compare to the enclosed chart.

NOTE: The analysis papers in each kit are different. Do not mix them, use the D4D analysis paper for D4D and the C&H analysis paper for the C&H.

Interpreting results:

Use the D4D pen first. Note the color change and compare that with the enclosed chart. To further identify a drug, use the C&H pen test and compare the color from that test. This will tell you what drug has been detected.
