Laboratory furniture and laboratory fume hoods are essential equipment in laboratories. They should not only possess excellent functionality and meet industry standards, but also have an attractive appearance and harmonious colors, while being environmentally friendly and energy-efficient to improve the indoor environment. Laboratory furniture is different from office furniture; 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, drug cabinets, vessel 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, cost-effective, but with a single style, suitable for customers pursuing economic benefits. (2) All-wood structure: All cabinets are made of engineered wood (medium-density fiberboard), colorful, but not moisture-resistant and with slightly poor load-bearing capacity, unsuitable for humid laboratories or those requiring high load-bearing, not recommended for use. (3) All-steel structure: Made from 1.0mm thick cold-rolled steel sheets through shearing, bending, and welding, all cold-rolled steel sheets undergo pickling and phosphating treatment followed by surface spraying with epoxy resin and high-temperature baking. Good load-bearing performance, sturdy, and durable. 3. By structure: fixed laboratory tables, suspended laboratory tables, and modular laboratory tables (1) Fixed laboratory tables: Supported by floor cabinets, the cabinet body can adopt all-wood structure or all-steel structure, lacking flexibility. (2) Suspended laboratory tables: The cabinet body rests on a metal frame, and the cabinet body can adopt all-wood structure or all-steel structure, with good moisture resistance and slightly better flexibility. (3) Modular laboratory tables: The cabinet body is equipped with movable wheels, and the cabinet body can adopt all-wood structure or all-steel structure, with the metal frame and tabletop forming an integral unit, good moisture resistance, convenient mobility, and better flexibility. During laboratory operations, a large amount of toxic and harmful gases are 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.
