Frequently asked questions

No. For the breathalyser to measure with maximum accuracy, it has to be calibrated with specialised equipment, which is available only at our service centre. Calibrating a device in good condition usually takes 30–40 minutes (not counting other work such as checks or repairs).

Yes. The accuracy of the sensor decreases over time, even when the device is idle. A breathalyser that has been out of use for more than a year, for example, must be recalibrated before its next test.

It depends on the model. The personal Alcotest 4000 needs calibrating once a year, however many tests it has done. The professional Alcotest 6000 and 6820 come with a calibration certificate valid for six months to a year; when it expires, calibration is repeated at our service centre. On request we also issue a metrological certificate valid for one year.

The Alcotest 5820, 6000, 6820, 7000 and 7510 take standard Slide ’n’ Click mouthpieces – without a valve or with a non-return valve for increased hygiene. The Alcotest 3820 and 4000 have their own mouthpieces with a protective cap. Each person tested uses a fresh mouthpiece.

The result appears in 3–5 minutes. The saliva test detects six drug classes at once and needs no power supply, so it is easy to use on site.

The EN 149 classes differ in the concentration of harmful substances at which the mask may be used: FFP1 up to 4 times the limit value, FFP2 up to 10 times and FFP3 up to 30 times (in accordance with EN 529:2005; national regulations may differ). FFP3 also protects against radioactive particles, enzymes and airborne biological agents of risk group 3. N95 masks are certified by the US National Institute for Occupational Safety and Health (NIOSH) and filter at least 95% of particles. On Dräger X-plore 1900 masks the class is easy to recognise by its colour: FFP1 yellow, FFP2 orange, FFP3 red.

Yes. It is a closed-type disinfection device: the ultraviolet radiation stays inside the unit and no ozone is released, so the room need not be vacated and the device can run around the clock.

A single crystal (monocrystal) is a crystal in which the atoms form one continuous lattice throughout the sample, with no grain boundaries. This distinguishes it from a polycrystal, which consists of many small crystals (grains) with different orientations. Thanks to its ordered structure, the properties of a single crystal are reproducible and depend on the direction within the crystal (anisotropy). That is why single crystals are needed wherever precise, predictable material properties matter: in microelectronics, optics, laser technology and scientific research. Examples of natural single crystals are quartz, diamond and topaz.

Synthetic single crystals are grown in laboratories and in industry when crystals of a given composition, size and purity are needed. The main methods are growth from the melt (for example the Czochralski and Bridgman methods), from solution and from the vapour phase, including chemical vapour transport. The quality of a crystal depends on the purity of the starting materials and on precise control of the temperature, its gradient and the growth rate. As a rule, the slower and more evenly the crystal forms, the fewer defects it has. Together with the Institute of Applied Physics, LABROMED LABORATOR grows niobium arsenide (NbAs) and niobium phosphide (NbP) single crystals for scientific research; both compounds are topological Weyl semimetals.
