The NV-1500 LX-O are specialized laboratory tables on a reinforced metal frame with a countertop width of 1500 mm. They are designed to accommodate heavy instruments, such as chromatographs or other analytical equipment. In the upper right corner of the table there is an electric panel with two sockets. Both sockets with grounding and shutters are designed for current up to 16 A and voltage up to 250 V. Working surface material: porcelain tile. It is moisture-resistant and 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 types of countertops for laboratory furniture. The tables have a metal frame painted with durable powder paint. 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 table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor. Dimensions of the table when assembled: 1500×700×850 mm. It is designed for standing work.

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.

Vascular Endothelial Growth Factor is one of the key regulators of angiogenesis. The most important role in the human body is played by a protein of the VEGF family called VEGF-A. VEGF-A is a 45 kDa glycoprotein homodimer and plays a key role in chemotaxis and angioblast differentiation, endotheliocyte (EC) proliferation, vasculogenesis, and vascular remodeling. As a result of alternative splicing or proteolytic cleavage, 4 main isoforms of VEGF-A are formed, consisting of 121, 165, 189, or 206 amino acid residues.
