Laboratory furniture and laboratory fume hoods are important equipment in laboratories. They should not only have excellent functional performance and meet industry standards, but also possess an attractive appearance and harmonious colors, as well as being environmentally friendly and energy-efficient to improve the indoor environment. Laboratory furniture is different from office furniture; its usage 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 tailored to 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, sampling benches, stainless steel benches, 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, 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 be equipped with mobile and fixed cabinets, has a good price-performance ratio, but has a single style, suitable for customers pursuing economic benefits. (2) All-wood structure: All cabinet bodies are made of man-made board (medium-density fiberboard), with rich colors, but not moisture-resistant and slightly lower load-bearing capacity, unsuitable for humid environments or laboratories with high load-bearing requirements, not recommended for use. (3) All-steel structure: Made of 1.0mm thick cold-rolled steel plate through 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. It has good load-bearing performance and is sturdy and durable. 3. By structure, it is divided into fixed laboratory benches, suspended laboratory benches, and modular laboratory benches: (1) Fixed laboratory benches: Supported by floor cabinets, cabinet bodies can use all-wood structure and all-steel structure, with insufficient flexibility. (2) Suspended laboratory benches: Cabinet bodies rest on a metal frame, cabinet bodies can use all-wood structure and all-steel structure, with good moisture resistance and slightly stronger flexibility. (3) Modular laboratory benches: Cabinet bodies are equipped with mobile wheels, cabinet bodies can use all-wood structure and all-steel structure, the metal frame and countertop form a unit, with good moisture resistance, convenient movement, 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.
