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, as well as being environmentally friendly and energy-efficient to enhance the indoor environment. Laboratory furniture differs from office furniture, as its use often involves contact with water, electricity, gas, chemicals, and equipment, which demands higher requirements for the structure and materials of the furniture. When constructing a laboratory, the design and selection of furniture must be based on 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-taking tables, stainless steel tables, etc.; (2) Laboratory cabinets include fume hoods, drug cabinets, utensil cabinets, gas cylinder cabinets, acid-base 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 a wooden cabinet body, can be equipped with movable and fixed cabinet bodies, cost-effective but with a single style, suitable for customers pursuing economic benefits. (2) All-wood structure: all cabinet bodies are made of artificial board (MDF), colorful but not moisture-resistant and with slightly lower load-bearing capacity, unsuitable for humid environments or high-load laboratories, not recommended for use. (3) All-steel structure: made from 1.0mm thick cold-rolled steel plates through cutting, bending, and welding, all cold-rolled steel plates undergo acid cleaning and phosphating treatment, followed by surface spraying with epoxy resin and high-temperature baking. It has good load-bearing performance, sturdy and durable. 3. By structure: fixed laboratory tables, suspended laboratory tables, separated laboratory tables (1) Fixed laboratory tables: supported by floor cabinets, cabinet bodies can use all-wood or all-steel structures, lacking flexibility. (2) Suspended laboratory tables: cabinet bodies rest on a metal frame, cabinet bodies can use all-wood or all-steel structures, with good moisture resistance and slightly better flexibility. (3) Separated laboratory tables: cabinet bodies are equipped with movable wheels, cabinet bodies can use all-wood or all-steel structures, the metal frame and tabletop form a unit, with good moisture resistance, easy to move, and good flexibility. During laboratory operations, a large amount of toxic and harmful gases is 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.
