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.
