The AVDM-250 high-vacuum unit is a structure consisting of a vacuum diffusion oil-vapor pump, a nitrogen trap, a vacuum gate, a frame or a plate. The principle of operation of the AVDM-250 unit is based on the pumping action of a vacuum diffusion steam oil pump. When the AVDM-250 unit is operating, liquid nitrogen is poured into the trap. Condensation of working fluid vapors occurs on the elements of the freezing device cooled with liquid nitrogen. The frame (plate) is designed for mounting the components of the unit. The ends of the wires are connected to a connector mounted on the frame of the AVDM-250 unit.

It is designed to maintain the set temperature of the liquid coolant circulating in the internal bath of the thermostat and in the connected external consumers. Feed pump for external closed-type thermostating systems. Cooling capacity 370 W at +20 °C. An internal bath with a volume of 27 liters and a depth of 200 mm. Operating temperature range -30...+100 °C. Overall dimensions 685x395x825 mm The open part of the bath is 320x220 mm Bath depth 200 mm Weight 56 kg Power consumption 3.5 kW.

The complete set is fully made of polypropylene. There are no components sensitive to the action of corrosive substances. Inside the storage area there are 2 compartments.In each compartment there is 1 easily removable shelf made of polypropylene with the possibility of installation at 3 levels in heightThe permissible load on the shelf is 30 kg. The storage cabinet also includes: 2 hinged facades made of polypropylene hinges outside the storage area (pin system) polyamide lock in each door handles made of polypropylene cabinet has a double back wall. Extraction of reagent vapors is carried out from all storage areas flange ∅ 100 mm on the back wall for connection to the exhaust ventilation hidden adjustable supports (0-40 mm). The adjustment of the supports is carried out from inside the pedestal through the base

The installation allows you to grow plants regardless of the time of year and weather conditions. Watering, ventilation and lighting of plants take place automatically. The system allows you to cultivate vegetable, berry, green, ornamental and medicinal plants. The equipment has a number of functions that allow you to identify the optimal modes of growing various crops: • Regulation of plant lighting modes • Plant nutrition management • Machine vision system (in the future, it will allow replacing humans and automatically controlling the microclimate, nutrition and lighting of plants to obtain maximum yields or plants with specified properties) These cultivation systems allow you to develop the following competencies: Chemistry – preparation of nutrient solutions; Biology – plant physiology, biochemistry, agronomy; Physics – spectral composition of light, hydrodynamics, energy supply of the system; Engineering – development of structural features of plant growing systems; IT – data collection and processing, training neural networks in decision-making algorithms; Economics – calculation of planting density, yield, and sales model. Growing plants in the city, in the vicinity of consumers, is mainstream all over the world. According to the UN, city farming will be the main direction of supplying fresh plant products to urban residents. In Russia, this area is especially relevant due to the natural and climatic characteristics of the country. The training of specialists and the development of this area will improve the quality of nutrition with vitamin products of the population and strengthen food security.

Vacuum spectrometers are designed for rapid analysis of alloys based on iron, copper, aluminum and other metals in factory and research laboratories, including the determination of elements having analytical lines in the field of vacuum ultraviolet (VUV) (for example, S, P and C in steels).

The measuring converter of the Earth's magnetic field is made on the basis of magnetoresistive sensors that simultaneously measure the orthogonal components of the magnetic field strength at the control point and the modulus of the intensity vector. At the same time, the magnetometer readings do not depend on the orientation of the measuring transducer in space. The MTM-01 magnetometer is also an effective means of measuring the quality of magnetic protections and screens to ensure the standards of electromagnetic safety of workers and the public during the operation of distribution transformers and electric power plants.

The spectrometer is designed to perform quantitative and qualitative spectral analysis of various substances and materials (powders, metals, solutions) in factory and research laboratories. The spectrometer is compact due to the vertical arrangement of the Paschen-Runge optical system. It consists of two MAES analyzers with 10 lines of photodiodes installed on a circle with a radius of 520 mm, a non-classical concave diffraction grating, a special table with a built-in computer and a spectrum excitation source.

CDL lasers of the KLM-355-x series are optimal sources of continuous radiation for the construction of control and automation systems, for scientific and medical purposes.

ConFlat (CF) standard connections are used еo ensure the connection of components of vacuum systems operating in the field of high and ultra-high vacuum.
