Laboratory furniture and laboratory fume hoods are essential equipment for laboratories. They should not only have excellent functionality and meet industry standards but also possess an aesthetically pleasing appearance and harmonious colors, as well as being environmentally friendly and energy-efficient to improve the indoor environment. Laboratory furniture differs from office furniture in that its use often involves contact with water, electricity, gas, chemicals, and instruments, thus placing higher demands on 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, it is divided into laboratory benches and laboratory cabinets: (1) Laboratory benches include side benches, central benches, instrument benches, overhead benches, washing benches, high-temperature benches, dissection benches, material collection benches, stainless steel benches, etc.; (2) Laboratory cabinets include fume hoods, medicine cabinets, utensil cabinets, gas cylinder cabinets, acid-base storage cabinets, specimen cabinets, sample cabinets, file cabinets, etc.; 2. By material, it is divided into steel-wood structure, all-wood structure, and all-steel structure: (1) Steel-wood structure: Composed of a metal frame and wooden cabinet body, it can have movable and fixed cabinet bodies, offering a high cost-performance ratio but with a single style, suitable for clients pursuing economic benefits. (2) All-wood structure: All cabinet bodies are made of man-made 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 environments and high load-bearing requirements; usage is not recommended. (3) All-steel structure: Made of 1.0mm thick cold-rolled steel plates cut, bent, and welded, all cold-rolled steel plates undergo acid pickling and phosphating treatment followed by surface spraying of epoxy resin and high-temperature baking. It has good load-bearing performance and is sturdy and durable. 3. By structure, it is divided into fixed laboratory benches, hanging laboratory benches, and separate laboratory benches: (1) Fixed laboratory bench: Supported by a floor cabinet, with cabinet bodies that can be made of all-wood structure or all-steel structure, lacking flexibility. (2) Hanging laboratory bench: The cabinet body rests on a metal frame, with cabinet bodies that can be made of all-wood structure or all-steel structure, offering good moisture resistance and slightly better flexibility. (3) Separate laboratory bench: The cabinet body is equipped with movable wheels, with cabinet bodies that can be made of all-wood structure or all-steel structure, where the metal frame and tabletop are integrated, offering good moisture resistance, ease of movement, and good flexibility.
