NV-1500 SHVD-M is one of the budget fume cupboards of the NV line. It is two-frame, with a laminated table top 700 mm deep. It is intended mainly for analytical laboratories. External dimensions of the cabinet (W×D×H): 1410×700×1960 mm. Dimensions of the working area (W×D×H): 1378×540×750 mm. Table top: laminated chipboard. A minimalistic solution for your laboratory The NV-1500 SHVD-M fume cupboard has a minimum of functions, but due to this it is inexpensive. The table top is made of laminated chipboard. It is relatively moisture-resistant, resistant to short-term exposure to acids, alkalis and organic solvents. This countertop does not tolerate strong heating or prolonged exposure to solvents, concentrated acids and alkalis. The working area is closed by two independent lifting frames with a counterweight. It has two exhaust zones: the hood of the exhaust box and the level of the countertop. Diameter of the flange for connection to the ventilation system: 150 mm. Working area size (W×D×H): 1378×540×750 mm. Please note that the cabinet narrows upwards. At a height of 50 cm, the depth of the working area will be 410 mm, at a height of 70 cm: 365 mm. If you need to place high equipment, then make sure that it corresponds to the dimensions of the camera, otherwise you will not be able to close the cabinet. The height of the raised glass above the cabinet: 510 mm, that is, when the glass is raised, the height of the cabinet will be 2470 mm. The working area is illuminated by an LED lamp (included in the package). The switch is located on the right-hand side of the cabinet body. The base of the cabinet is an all-welded metal frame in powder coating. The side laminated panels (chipboard 16 mm thick) are edged on the facade with a durable PVC edge 2 mm thick, which increases their impact resistance and mechanical strength. The cabinet legs are adjustable in height within two centimeters, allowing you to place the cabinet even on a fairly uneven floor.

The NV-1200 VG is a specialized laboratory table with a damping concrete slab on a sand cushion. It is designed to accommodate sensitive analytical equipment, primarily scales. Dimensions when assembled: 1200×600×750 mm. It is designed to work while sitting. The table has a reinforced metal frame. The main countertop has a built-in drawer open from above, which contains a sand cushion. It is closed with a heavy concrete slab attached to a second, smaller countertop. The sand cushion and the concrete base of the second countertop provide good protection against vibrations. Working surface material: laminate. It is well suited for the placement of devices, but is not resistant to concentrated acids, alkalis and organic solvents. The size of the anti-vibration countertop: 400×400 mm. For maximum isolation from vibrations, the scales should be placed in the center of this countertop. The tables have a metal frame painted with durable powder paint. The side laminated panels (chipboard 16 mm thick) are edged with a durable PVC edge 2 mm thick, which increases their impact resistance and mechanical strength. The legs of the table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor.

The digital contact thermometer TK-5.01PTS is designed to measure the temperature of the surface of solids by direct contact of the probe with the measuring object. The digital contact thermometer consists of an electronic unit and a non-replaceable surface probe. Thermoelectric converters (TP) with NSH according to GOST R 8.585 are used as a thermosensitive element in the probe.

The NV-750 VG is a specialized laboratory table with a damping concrete slab on a sand cushion. It is used to keep sensitive analytical equipment, primarily scales. The table is designed for sitting work. Dimensions when assembled (W×D×H): 750×600×750 mm. The size of the countertop for scales: 400×400 mm. Special anti-vibration design The three-layer design of the table allows you to maximally dampen vibrations that prevent the accurate operation of the scales: 1st layer: sand cushion. The main countertop has a built-in drawer open from above, which contains a sand cushion. 2nd layer: concrete slab — weighting. A heavy concrete slab is placed on a sand cushion. 3rd layer: a small table top. The small table top is attached to the concrete slab, completely covers it and does not come into contact with the main table top (and, therefore, does not transmit vibrations from it). The size of anti-vibration (small) table tops: 400×400 mm. For maximum isolation from vibrations, the scales should be placed in the center of this countertop. Table base: all-welded metal frame, painted with white powder paint. The design does not use rubber dampers, which have a limited service life. Both countertops are made of laminated chipboard. It is well suited for the placement of devices, but is not resistant to concentrated acids, alkalis and organic solvents. The damping surface protrudes above the main tabletop, but visually it does not differ from it in any way. The countertops and side laminated panels (chipboard 16 mm thick) are edged with a durable PVC edge 2 mm thick, which increases their impact resistance and mechanical strength. The legs of the table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor.

At the Scientific Research Center of the Russian Academy of Sciences, the technology of acousto-optic filtration of optical radiation is used to create a wide class of optical devices that are successfully used, for example, in biomedicine to diagnose various diseases (including oncology), in agriculture to diagnose the condition of plants, during non-destructive testing of complex technical objects and in solving other tasks. Acousto-optics has a number of important advantages over other technologies for obtaining spectral information: - the ability to create imaging devices without spatial scanning, since the acousto-optic filter is a software-controlled tunable light filter; - the compact modular design allows the acousto-optic filter to be integrated into the optical circuit of most imaging devices, which expands their analytical capabilities; - spectrum scanning is carried out by means of an electrical signal, without mechanical scanning; - fast arbitrary spectral addressing causes high shooting speed and the absence of redundant information; - software management. The key element of the presented device – an acousto–optic filter - is being developed at the Scientific Research Center of the UP RAS on the basis of original calculation methods. The manufacture of acousto-optic filters, optical and mechanical components, as well as the assembly, tuning, and calibration of such devices is also carried out at the Scientific Research Center of the UP RAS.
