Laboratory furniture and laboratory fume hoods are essential equipment for laboratories. They should not only have excellent functional performance and comply with industry standards, but also possess an attractive appearance and harmonious colors, as well as being environmentally friendly and energy-efficient to improve the indoor environment. Laboratory furniture differs from office furniture as its use often involves contact with water, electricity, gas, chemicals, and instruments, thus imposing higher requirements on the structure and materials of the furniture. When constructing a laboratory, the design and selection of furniture must be tailored to the laboratory's work content, environmental conditions, and specific requirements. 1. Classification of laboratory furniture: 1. By function: laboratory tables and laboratory cabinets (1) Laboratory tables include side tables, central tables, instrument tables, ceiling tables, washing tables, high-temperature tables, dissection tables, material collection tables, stainless steel tables, etc.; (2) Laboratory cabinets include fume hoods, medicine cabinets, utensil cabinets, gas cylinder cabinets, acid and alkali storage cabinets, specimen cabinets, sample cabinets, file cabinets, etc.; 2. By material: steel-wood structure, all-wood structure, all-steel structure. (1) Steel-wood structure: composed of a metal frame and wooden cabinet body, can be equipped with movable and fixed cabinets, offering high cost-performance but limited styles, suitable for customers pursuing economic benefits. (2) All-wood structure: all cabinet bodies are made from engineered wood (medium-density fiberboard), rich in colors but not moisture-resistant and slightly lower in load-bearing capacity, not suitable for damp laboratories or those with high load-bearing requirements; not recommended for use. (3) All-steel structure: made from 1.0mm thick cold-rolled steel sheets that are cut, bent, and welded, all cold-rolled steel sheets are treated with acid pickling and phosphating, followed by surface spraying of epoxy resin and high-temperature baking. It has good load-bearing performance and is solid and durable. 3. By structure: fixed laboratory tables, suspended laboratory tables, and combined laboratory tables. (1) Fixed laboratory tables: supported by floor cabinets, cabinet bodies can be made of all-wood or all-steel structures, lacking flexibility. (2) Suspended laboratory tables: cabinet bodies rest on a metal frame, capable of using all-wood or all-steel structures, with good moisture resistance and slightly better flexibility. (3) Combined laboratory tables: cabinet bodies are equipped with movable wheels, can use all-wood or all-steel structures, the metal frame and tabletop form a single unit, offering good moisture resistance, easy mobility, and good flexibility. During laboratory operations, a large amount of toxic and harmful gases may be generated, which must be expelled outdoors through ventilation and exhaust systems to reduce harm to laboratory personnel and create a comfortable and safe working environment.
