The use of the SmartRack® saves costs as early as the laboratory planning stage. The more efficient use of space eliminates the cost-intensive construction of laboratory space. In addition to the construction costs, other costs can also be saved by the lesser need for equipment. In the case of special laboratory fume hoods and safety cabinets, the savings due to the use of the SmartRack® are increased, since by reducing the width of a fume hood or safety workbench by one or two laboratory grids, e.g. from grid width 1,800 mm to 1,500 mm or 1,200 mm, significantly more costs for investment in laboratory equipment can be saved.
