THe Kors NV-1250 SHV-BC laboratory fume cupboard is a single—frame cabinet with a width of 1240 mm and with a table top made of monolithic ceramics. External dimensions of the cabinet (W×D×H): 1240×700×1960 mm. Dimensions of the working area (W×D×H): 1208×660×1072 mm. Table top: monolithic ceramic. Convenient fume cupboard for comfortable work in the laboratory The table top made of monolithic ceramics is moisture-resistant, perfectly withstands high temperatures. Due to the lack of seams, ceramic granite tiles are better resistant to chemicals and heat. It is possible to place high-temperature equipment on it. The working area is closed by a single lifting frame with a counterweight. There are two exhaust zones in it: 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): 1208×540×750 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 it will be 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 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 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. And if we need a cabinet for muffle furnaces? If you need a cabinet to accommodate high-temperature equipment, you might be interested in the ballscrew models. The depth of the countertop is specially increased so that you can put an oven or a cabinet.
