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.

Purpose measurement of the ambient dose equivalent of N*(10) gamma radiation; measurement of ambient dose equivalent of H*(10) gamma radiation; assessment of surface contamination with radionuclides.

The sample heating system is designed to expand the capabilities of standard set-top boxes NPVO-ZDO and NPVO-A. It consists of a heated replaceable frame with a diamond prism and a temperature controller unit. For most solid samples in the heated state, it is possible to obtain a much more pronounced NPV spectrum than in the cold state. This makes it possible to increase the sensitivity of the method several times. The properties of some substances and compounds change dramatically with an increase in temperature, chemical interaction processes between components, their decomposition, oxidation in air, etc. may occur. If changes in the chemical composition of a substance occur during heating, a set of spectra corresponding to the kinetics of the process can be obtained with the help of an NPVO prefix with a diamond thermocell and a temperature controller, which is essential expands the possibilities of the method in research. Technical characteristics of the NPVO set-top box with a thermocell and a controller Transmission in the operating range of the spectrum, % of the input signal at least 10 The recommended number of scans when registering spectra is 25 Spectrum registration time at 25 scans (resolution 4 cm-1), sec 30 The depth of penetration of radiation into the sample, microns 5 – 15 Minimum dimensions of the solid sample, mm 0.5 × 0.5 Minimum volume of the liquid under study, ml 1 Minimum dimensions of the fiber sample: cross-section diameter/length, mm 0.3/1 The material of the crystal substrate is DIAMOND The diameter of the free zone of the crystal, mm not less than 2 x 3 The diameter of the focus spot, mm 1.5 Maximum temperature With 220o Adjustment accuracy, With 1o Time to reach the maximum temperature, min 10 Overall dimensions, mm 130×200×90 Weight, kg 1,2

The Rotary Evaporator Trap is manufactured by PrimeLab for the purpose of collecting and condensing evaporative liquids during evaporation processes. Made of transparent borosilicate glass, which allows you to observe everything that happens inside the trap. 2 tubes with olives are soldered into the outer part of the trap for connection to other equipment. One of them is located at the top of the device, the second at the bottom. The PrimeLab company offers glassblowing services for the production of a wide variety of borosilicate glass products according to the customer’s specifications.

Dry coolers (autonomous cooling system) are designed to circulate and cool the liquid, which ensures the permissible temperature of the heat-generating object. The product is adapted to work with vacuum drying cabinets of the "SNVS" and "SHSV" type manufactured by TULA-TERM LLC, having a liquid-cooled flange, as well as any equipment using liquid cooling and suitable in characteristics.
