The working condition of the ND-250(P) diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (under technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-250(R) diffusion pump is a maximum of 1.8 liters, a minimum of 1.3 liters. The viewing window for visual inspection of the working fluid has labels of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid almost does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-250(R) diffusion pump using the same temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the pump up to 320˚C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 160 l/h, for the oil reflector it is 20 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).

Kors NV-1200 SHV-B laboratory fume hoods are single—frame cabinets with a width of 1100 mm with a countertop made of granite tiles. External dimensions of the cabinet (W×D×H): 1100×700×1960 mm. Dimensions of the working area (W×D×H): 1068×540×750 mm. Table top: granite tiles. Convenient fume cupboards for comfortable work in the laboratory The cabinet is available in two versions: with a hood from the lower cabinet and without it. In a cabinet with a hood, various aggressive reagents can be stored, in a cabinet without a hood, it is better to store only laboratory glass or instruments. Working surface material: porcelain tile. It is moisture-resistant, perfectly withstands high temperatures. It is resistant to prolonged exposure to concentrated acids, alkalis and organic solvents. It has limited resistance to hydrofluoric acid. This is one of the most popular choices for work surfaces, suitable for most laboratories. Drying cabinets or other highly heated appliances can be placed on such a countertop. The working area is closed by a single lifting frame 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): 1068×540×750 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, with the glass raised, the total height of the cabinet will be 2470 mm. The working area is illuminated by a fluorescent lamp (included in the package). The switch is located on the right side of the cabinet, next to the sockets. The fume cupboard is equipped with two sockets, one of them with grounding. Sockets with IP20 degree of protection, maximum load: 1.5 kW. The base of the cabinet is an all-welded metal frame in powder coating. The side laminated panels (chipboard with a thickness of 16 mm) are edged with a durable PVC edge with a thickness of 2 mm, which increases their impact resistance and mechanical strength. The legs of the cabinet are adjustable in height within two centimeters, allowing you to place the cabinet even on a rather uneven floor.

Adsorption nitrogen plant is a set of equipment for the production of nitrogen from atmospheric air by short–cycle heat-free adsorption at a pressure of up to 13 bar. The adsorption nitrogen plants of the Provita company allow to produce nitrogen with a purity of up to 99.9999%. The capacity of the plants ranges from several liters per minute to hundreds of cubic meters per hour. The basis of the installations are nitrogen adsorption generators developed and manufactured by our company. A carbon molecular sieve with a developed microporous structure is used as an adsorbent. The gas generator requires dry compressed air with a pressure of at least 6 bar to operate, so the installation includes an air compressor, as well as a dehumidifier and an air receiver (if they are not part of the compressor). The source air must be cleaned of dust and oil, which is carried out by the main filters included in the installation or directly by the nitrogen generator. The nitrogen receiver is used for the accumulation of production gas.
