NV-1210 PC is a wall table with a superstructure in the NV line. The table top is made of monolithic ceramic with a depth of 70 cm and a width of 121 cm. A lamp and two sockets are built into the superstructure. It is designed for standing work: the height of the table top is 85 cm. External dimensions of the table (W×D×H): 1210×700×1650 mm. The table top made of monolithic ceramics is moisture-resistant, perfectly withstands high temperatures. It is more resistant to chemicals and heat than ceramic tile since there are no seams. The superstructure allows you to compactly place the necessary reagents and laboratory utensils next to the workplace. Its depth is 25 cm, and its height is 80 cm. The working area is illuminated by a fluorescent lamp (included in the package). The switch is located on the left-hand side of the superstructure. There are also two sockets, one of which is grounded. Sockets have the IP20 degree of protection, maximum load: 1.5 kW. On the right-hand side under the table top there is a built-in cabinet with three drawers. You can store laboratory utensils, equipment accessories or other small things there. The side laminated panels of the table (chipboard 16 mm thick) are edged with a 2 mm PVC edge, 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.
