The novel portable 'micro-laboratory', with its sensitive, simple, rapid, precise and reliable operation, revolutionises the field task of police and other security agencies in the detection and identification of explosives.
The ETK5 is an upgraded improved version of our original ETK. ETK5 was expanded to detect an additional class of explosives which is based on chlorate salts. The stability and reliability of ETK5 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.
- Detection of persons having handled explosives.
- Detection of surfaces having had contact with explosives.
- Identification of explosives.
ETK5 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.
The ETK5 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.
The ETK5 has been succesfully used by many police and security forces around the world.
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")
ETK5 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). 
ETK5 reagents are guaranteed for one year under normal environmental storage conditions (25 degrees
Celsius). ETK5 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).
The kit is environmentally safe and has no effect on the Ozone level (no spraying procedures).
The ETK5 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.
Group A: TNT, Tetryl, TNB, Picric acid and its salts = 0.1 - 1 micro gram.
Group B: Dynamite, RDX, PETN, Nicrocellulose Smokeless Powder and
plastic explosives such as C4 and SEMTEX = 0.01 - 1 micro gram.
Group C: Nitrate Salts = 0.1 micro gram.
Group D: Chlorates = 10 micro gram.
Group E: TATP = 10 micro gram.
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.
The tests takes a few seconds, from the time of sampling until final results are obtained, enabling quick screening of large numbers of suspects.
Test results in case of positive identification, are characterized by the appearance of intense colors clearly visible on the test paper.
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.
ETK5'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. 
The ETK5 provides classification of the detected explosives into five main groups:
A: Polynitro aromatics (Positive reaction using Reagent No.1 only).
B: Nitrate esters and nitramines (Positive reaction using Reagent Nos. 1 and 2).
C: Nitrate salts (Positive reaction using Reagent Nos. 1, 2 and 3).
D: Chlorates (Positive reaction using Reagent No. 4).
E: TATP (Positive reaction using Reagent No. 5).
