A feature of the POWDIX 600 X-ray diffractometer scheme is the vertical Bragg-Brentano optical scheme with a fixed horizontal sample position, which makes working with powdery materials, gels and other viscous substances more practical and convenient. The high detector resolution and precise positioning of the POWDIX 600 X-ray goniometer achieve an accuracy better than +/- 0.02° (2θ) over the entire angular range. In the POWDIX 600 diffractometer, the X-ray tube is cooled by an integrated closed water circuit, which can be serviced by any laboratory employee. A wide variety of sample holders (holder for massive samples, holder with rotation, phoneless cuvettes) expands the functionality of the POWDIX 600 and makes it an invaluable tool for scientific research in solid-state physics, materials science, chemistry, geology and other fields of science The diffractometer is included in the Russian State Register of Measuring Instruments.

The XRF analyzer BRA-135F is an energy dispersive spectrometer which can simultaneously determine the presence of up to twenty chemical elements - from 9F to 92U - in the analyzed sample. Samples can be in liquid, solid, powdered or deposited on a substrate. The analyzer captures concentrations from tenths of mg/kg. The model BRA-135F performs quantitative/semi-quantitative spectral analysis of steel and alloys. It also performs spectral analysis of oil, petroleum and other petroleum products, detecting in their composition even the smallest concentrations of impurities of various metals. The vacuum sample chamber and ultra-slim detector inlet provides a low detection limit in the range of light elements from 9F to 17Cl. The high-performance silicon drift detector (SDD) with an energy resolution of less than 135eV allows the separation of spectral lines of almost all elements, which makes the analysis of complex multicomponent substances (high-alloy steels, precision alloys, polymetallic ores, etc.) possible.

It is a modern high-precision device (a variant of the ION-3701 device) and used for a wide range of tasks in areas where it is necessary to determine the magnitude of the magnetic field and residual magnetization in shop conditions, on the conveyor, during acceptance and inspection of parts and workpieces. It is equipped with a three-dimensional magnetic field sensor and has outstanding technical characteristics and extensive functionality.
