Laboratory furniture and laboratory fume hoods are important equipment in laboratories. They should not only have excellent functionality and comply with industry standards, but also possess an aesthetically pleasing appearance and harmonious colors, while being environmentally friendly and energy-efficient to improve the indoor environment. Laboratory furniture differs from office furniture; its use often involves contact with water, electricity, gas, chemicals, and instruments, thus placing higher demands on the structure and materials of the furniture. During laboratory construction, furniture design and selection must be based on the laboratory's work content, environmental conditions, and specific requirements. 1. Classification of laboratory furniture: 1. By function: laboratory benches and laboratory cabinets (1) Laboratory benches include side benches, central benches, instrument benches, overhead benches, washing benches, high-temperature benches, dissection benches, specimen benches, and stainless steel benches. (2) Laboratory cabinets include fume hoods, drug cabinets, utensil cabinets, gas cylinder cabinets, acid and alkali storage cabinets, specimen cabinets, sample cabinets, and file cabinets. 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, has a high cost-performance ratio, but the design is simple, suitable for clients pursuing economic benefits. (2) All-wood structure: all cabinet bodies are made of artificial board (medium-density fiberboard), with rich colors, but it is not moisture-resistant and has slightly lower load-bearing capacity, making it unsuitable for humid laboratories or those requiring high load-bearing; usage is not recommended. (3) All-steel structure: made from 1.0mm thick cold-rolled steel plates cut, bent, and welded, all cold-rolled steel plates undergo acid washing and phosphating treatment, followed by a surface spray of epoxy resin and high-temperature baking. It has good load-bearing performance, is sturdy and durable. 3. By structure: fixed laboratory benches, suspended laboratory benches, and modular laboratory benches. (1) Fixed laboratory benches: supported by floor cabinets, with cabinet bodies available in all-wood and all-steel structures, lacking flexibility. (2) Suspended laboratory benches: cabinet bodies rest on a metal frame, with cabinet bodies available in all-wood and all-steel structures, having good moisture resistance and slightly stronger flexibility. (3) Modular laboratory benches: cabinet bodies are equipped with movable wheels, with cabinet bodies available in all-wood and all-steel structures, integrating the metal frame and tabletop as one, offering good moisture resistance, ease of movement, and flexibility.
