Equipment

High-temperature furnaces are capable of heating materials up to 1700 degrees. The scope of their application covers the heat treatment of various materials in an inert medium or vacuum. TULA-TERM furnaces are used for heat treatment of plastics, ceramics, metals, alloys, lacquers and other materials. The equipment allows sintering, annealing, soldering, quenching, drying, burning and molding. In industry, our installations are most often used for quenching parts and sintering hard alloys.

They are designed for carrying out various technological processes at temperatures from 40 to 500 oC, in vacuum up to 1x10−3 mmHg, or in an inert gas of high purity. They are used for drying, light annealing, aging, low and medium tempering in an oxidizing environment, degassing of ferrous and non-ferrous metals (including copper and copper alloys), or any other materials processed under similar conditions. The program setting of heat treatment modes including vacuuming, high purity inert gas intake with repeated vacuuming allows heating in an oxidizing environment with high purity of the surfaces of the processed parts, without scale formation and oxidation.

The ASE-2 energy dispersive sulfur analyzer is designed to measure the mass fraction of sulfur in unleaded gasoline, diesel fuel, crude oil, kerosene, oil residues, lubricating oil bases, hydraulic oils, jet fuels and other distillate oil products. X-ray radiation from a low-power X-ray tube, converted by a primary radiation filter, excites fluorescence emission from the atoms of the sample being analyzed. The fluxes (primary X-rays scattered on the sample and secondary fluorescence) of radiation fall on a gas proportional counter, whereby the fluorescence radiation of sulfur atoms (SKa) is separated from the radiation with other energies by means of selective filters. The intensity of the fluorescence emission of sulfur atoms registered by the gas proportional counter is proportional to the mass fraction of sulfur in the analyzed sample.

Automated device for measuring the content of toxic trace elements (As, Cd, Pb, Cu, Zn, Mn, Hg, Se, I, Ni, Co, Fe, Ag, Sb, Bi, Fe, Sn) in water, soil, food products by voltammetric methods with sensitivity at 1/10 of the permissible level (MPC) and below.

The AVD-50/5 unit consists of a NVD-200 series-connected two-rotor vacuum pump and a 2NVR-5DM plate-rotor vacuum pump. 2NVR-5DM and NVD-200 pumps are installed on the lower and upper base of the frame and secured with bolts, nuts and washers. The pumps are connected to each other by means of a pipeline and a bellows assembly. By installing the rings during assembly of the unit, the size of the bellows assembly is set. The AVD-50/5 unit can operate continuously at an inlet pressure of no more than 133 Pa (1 mm Hg) or pumping out one or more sealed vessels with a total volume of 3.5 m3 from atmospheric to maximum residual pressure for 8 hours.

The spectrometer was created according to the Cherni-Turner scheme based on a flat diffraction grating and an MAES analyzer with one line of photodetectors. It has increased photometric accuracy due to cooling and temperature stabilization of the photodetector range, as well as due to its shell-less design, in which there is no re-reflection of radiation on the cover glass and the background level in the recorded spectrum decreases. The optical scheme and design of the spectrometer are optimized to obtain a high-quality spectrum with a low level of background radiation in any of the regions lying in the spectral range of 190-1100 nm. The choice of the working area is carried out by changing and rotating the diffraction gratings. The sealed case of the spectrometer is filled with an inert gas. The radiation is injected into the spectrometer using a quartz capacitor or a fiber-optic cable with an SMA-905 connector. The optical scheme and design of the spectrometer are protected by patents.

Vacuum resistance furnaces are necessary for heating products before pressure treatment, for sintering, degassing, quenching, annealing, soldering and chemical-technological processes. Such furnaces among all the variety of thermal equipment are considered the most environmentally friendly – heat treatment is carried out at t up to +2500 ° C in a purified vacuum. Under certain conditions, vacuum furnaces are used to work with neutral gases. The outer part of the furnace is made of stainless steel and is cooled by liquid. The inner part of the working chamber, where the heat treatment of materials is carried out, is made of an alloy of molybdenum and tungsten. The components are characterized by a low inertia force, reduced gas separation. The settings are available on the control panel, where the instruments, automatic and manual control switches are located. At every enterprise of the electronic industry, nuclear power, an explosion-proof vacuum resistance furnace is needed. The same applies to areas where various products undergo heat treatment at the stage of production and preparation for use

The spectrometer is designed to determine the contents of elements in the range from Ca to U in substances in solid, powdery, dissolved states, as well as deposited on the surface or deposited on filters. The principle of operation of the spectrometer is based on irradiation of the sample with primary radiation from an X-ray tube, measurement of the intensity of secondary fluorescent radiation from the sample at wavelengths corresponding to the elements being determined, and subsequent calculation of the mass fraction of these elements according to a pre-constructed calibration characteristic, which is the dependence of the content of the element being determined on the measured intensity. Secondary fluorescent radiation is decomposed into a spectrum using a crystal analyzer. Due to this, the spectrometer has a high resolution, and therefore the ability to accurately analyze complex multicomponent substances.

The LI-400 integrated flanged trap is installed inside the diffusion pump instead of the standard oil reflector, without increasing the overall dimensions of the diffusion pump. The LI-400 trap performs the function of an oil reflector, is installed instead of a standard oil reflector in pumps, has an additional number of cooled screens for capturing oil return flow vapors (more than that of the MU trap), covers the entire area of the input high-vacuum flange.
