A portable micro-laboratory for rapid explosives detection
The novel portable 'micro-laboratory', ETK five, with its sensitive, simple, rapid, precise and reliable operation, revolutionizes the field task of police and other security agencies in the detection and identification of explosives.

ETK five is an upgraded improved version of our original ETK. ETK five was expanded to detect an additional class of explosives which is based on chlorate salts. The stability and reliability of ETK five is also enhanced. The time period for using the various reagents after breaking the ampoulses was extended to at least to weeks at 25 degrees Celsius.

Objectives

• Detection of persons having handled explosives.
• Detection of surfaces having had contact with explosives.
• Identification of explosives.

Detection
ETK five enables simple, rapid end reliable detection of persons engaged in preparing, handling or carrying explosive charges, and allows for fast screening of suspects in the field. The kit aids in detection, through exposure and proof of contact contamination of various surfaces, by explosives.

Identification
The ETK five distinguishes between explosives and non-explosive materials. Furthermore, the kit is capable of identifying four classes comparising the majority of explosives currently in use, and revealing their traces on the boday and various items such as clothes, suitcases, door handles and car surfaces.

Proven experience
The ETK five has been succesfully used by Israeli police and secutiry forces of other countries around the world.

Compactness
The compactness, portability and self-sufficiency of the kit assures convenient hand-carrying or attachment to a service-belt, and can be employed anywhere under a wide range of conditions.
Weight - approx. 400 gr. (16 oz.) Length - 23 cm (15"). Depth - 18.5 cm (7.4"). Height - 4.5 cm (1.8")

Safety
ETK five is extermely safe for both operator and suspect, as there is no direct contact with the chemical components used in the test. All of the test reagents are contained within glass ampoules in specially designed protective plastic tubes. The test is performed by applying a few drops of reagents on absorbing paper (no spraying of chemicals).

Shelf life
ETK five reagents are guaranteed for one year under normal environmental storage conditions (25 degrees
Celsius). ETK five may be kept for an extended period under refrigeration (4 degrees Celsius). After crashing the ampoules, reagents reliability is guaranteed for up to 2 weeks (25 degrees Celsius).

Environment
The kit is environmentally safe and has no effect on the Ozone level (no spraying procedures).

Range of identification
The ETK five is capable of identifying the full range of well known types of military and comercially available explosives, and also of homemade explosives based on nitate and chlorate salts.

Test sensitivities

Group E: TATP = 10 micro gram.

No false alarms
There are no known false alarams, whit the rare exception of some nitro-cellulose-based paints while they are fresh. In such instances, further investigation will clarify and remove any doubtful results.

Rapid Results
The tests takes a few seconds, from the time of sampling until final results are obtained, enabling quick screening of large numbers of suspects.

Unequivocal results
Test results in case of positive identification, are characterized by the appearance of intense colors clearly visible on the test paper.

No interference with most other forensic tests
By use of dry sampliing and spot tests on samples, most other crime tests, such as fingerprinting of suspects, can be done, after the sampling.

Simplicity
ETK five's simple design and mode of operation specifically developed for ease of handling, can be operated after only a few minutes of easily followed instructions.

Definition of explosives
The ETK five provides classification of the detected explosives into five main groups:
