It is intended for express analysis of various types of solid and liquid samples, including polymer particles, films and fibers, powdery substances, fragments of paint coatings, fuels and lubricants. The presence of an optical system for visual inspection of the surface under study with an increase of 75X ensures high efficiency when working with small samples – fragments of thin fibers, microparticles, etc. The universal clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements. For convenience when working with liquid and paste-like samples, as well as in the ZDO mode, it is possible to rotate the clamping console by 180o. The console is equipped with two replaceable tips – with a spherical working part and with a flat hinged head. A replacement table is used to register the specular and diffuse reflection spectra. The sample is located on the subject plane of the investigated surface downwards, the angle of incidence of the central beam on the sample is 45 °. The method is used to determine the spectral characteristics of optical parts, crystals, thin films on the surface, as well as to register the absorption spectra of large solid objects. Transmission in the operating range of the spectrum, % of the input signal at least 30 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 area of a solid sample, mm 0.2 × 0.2 Minimum volume of the liquid under study, ml 1 Minimum dimensions of the fiber sample: cross-section diameter/length, mm 0.1/1 Substrate crystal material ZnSe CVD, Ge Focusing spot diameter, mm 1 The angle of incidence of radiation (central beam) on the sample in the ZDO mode 45o Magnification of the micro lens / total magnification of the visual channel 4X /75X Field of view of the optical system, mm 2 X 2.5 Digital video camera resolution 640 X 480 Overall dimensions, mm 150×150×260 Weight, kg 2.15 • Allows you to study objects of small size (from 200 microns - depending on the geometry, surface quality and physico-chemical properties of the material) • The attachment allows you to work without sample preparation, has a fixed adjustment of the pressure on the sample using a clamp equipped with color indicators • Thanks to the removable flange with the NPVO element, a quick and convenient sample change and cleaning of the crystal surface is provided • At a given optimal contact force, the method provides high quality and repeatability of results due to the absence of influence of the thickness of the substance layer on the shape of the spectrum and the intensity of the absorption bands • The sample retains its original physical and chemical properties and, if necessary, can be further investigated by other methods

The Korsa NV-1500 SHV-PB laboratory fume cupboard is a single—frame cabinet with a width of 1410 mm with a table top made of polypropylene. 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: polypropylene. A reliable fume cupboard for laboratories Working surface material: monolithic polypropylene. It is moisture-resistant, resistant to prolonged exposure to concentrated acids, alkalis and organic solvents. Poorly resistant to high temperatures. Polypropylene countertops are suitable for chemical laboratories that work a lot with concentrated inorganic acids and alkalis. 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): 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, with the glass raised, the total 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, next to the sockets. The fume cupboard is equipped with two sockets, one of them with grounding. Sockets have the 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 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 rather uneven floor.

The 3VVN1-3M(N) water ring vacuum pump with a capacity of 3.5 m3/min at an initial pressure of 0.04 MPa is designed for general industrial use, to create and maintain a vacuum in the operating pressure range from atmospheric to 10 kPa.
