Surface Drug Test Kits. Forensic tests

Employers frequently schedule a time when they can test their employees for evidence of drug use. Yet smart employers do not stop with the testing of workers, they also test the various surfaces in certain areas of the workplace.

Now an employer realizes that an employee is not apt to light up a stick of marijuana while carrying out an assigned duty. However, no employee remains at work during the entire eight hours of the typical workday. Employees visit the restroom, remove and store articles from lockers, and handle numerous objects, any of which could pick up trace elements of an illicit drug.

One company has used that fact, in order to facilitate the detection of cocaine use. That company markets special drug test swipes. Each swipe is the size of a postcard, and promises immediate results. It turns blue, if it picks up traces of cocaine.

A second company makes a Detect 4 Drugs aerosol spray. The spray can comes in a kit, along with a collection of test paper. The testing agent wipes the surface with the paper and then covers it with one of four different sprays. The chemicals in the spray cans give them the ability to pick up traces of four different drug types.

The contents of one spray can produce evidence that a worker has been using marijuana, hashish or other cannabinoids. The content of a second spray has the ability to signal use of cocaine or crack. The chemicals in a third spray allow it to detect heroin and china white. The contents of the fourth and final spray can furnish an employer with proof that a worker has been using methamphetamines.

Frightening incidents, such as those associated with the mysterious "postal bomber" gave rise to creation of items such as the See Through Transparency Spray. This item is used to inspect envelopes or packages, without opening them. If the inspected container contains a powder, then a darkened area will appear on the transparent sheet.

The person who is curious about the contents of a package needs to wrap it in a transparent sheet. Once wrapped in that sheet, the suspect package needs to be sprayed. Once sprayed, the transparent sheet reveals the contents of any package that it covers. The spray does not leave any traces, and it does not produce any running ink.

While most employers plan to look for evidence of drug use, when they order a series of surface tests, homeowners might want to test the surface of fruits and vegetables. Homemakers and home cooks might want to make sure that no produce in the family's residence contains harmful microbes. Forensic testing devices can be used for such a determination.

This kits can contain self-filling ampoules with pre-measured and pre-mixed ingredients. The presence of microbes causes a change in the color of the filled ampoule. Once a color change has been detected, the ampoule can be sent to a lab, for confirmation of the fact that the suspected microbe is indeed present on the surface of fresh fruits and or vegetables.
