Laboratory furniture and laboratory fume hoods are important equipment in laboratories. They should not only have excellent functionality and meet 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 as its use often involves contact with water, electricity, gas, chemicals, and instruments, which imposes higher requirements 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: laboratory benches and laboratory cabinets (1) Laboratory benches include side benches, central benches, instrument benches, ceiling 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 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 mobile and fixed cabinet bodies, cost-effective but with limited styles, suitable for customers pursuing economic benefits. (2) All-wood structure: All cabinet bodies are made of artificial board (medium density fiberboard), available in rich colors, but not moisture-resistant and with slightly lower load-bearing capacity, unsuitable for humid laboratories or those requiring high load-bearing, not recommended. (3) All-steel structure: Made of 1.0mm thick cold-rolled steel plates processed by cutting, bending, and welding. All cold-rolled steel plates undergo acid cleaning and phosphating treatment, followed by spraying with epoxy resin and high-temperature baking. Excellent load-bearing performance, sturdy and durable. 3. By structure: fixed laboratory benches, hanging laboratory benches, and separate laboratory benches (1) Fixed laboratory bench: Supported by a floor cabinet, cabinet bodies can use all-wood structure and all-steel structure, lacking flexibility. (2) Hanging laboratory bench: Cabinet body rests on a metal frame, cabinet bodies can use all-wood structure and all-steel structure, good moisture resistance, slightly more flexible. (3) Separate laboratory bench: Cabinet body is installed with movable wheels, cabinet bodies can use all-wood structure and all-steel structure, metal frame and tabletop form a unit, good moisture resistance, easy to move, and flexible. 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.
