Specialized equipment category for laboratory benches and draft chambers used in manufacturing R&D and quality control departments. Includes safety equipment necessary for handling hazardous materials and precision experiments such as chemical laboratory benches, physics laboratory benches, clean benches, fume hoods, and glove boxes. Products primarily feature chemical resistance, explosion-proof specifications, exhaust functions, and temperature/humidity control capabilities, designed to ensure worker safety and maintain experimental environments in material development, quality testing, and analytical work. Unlike general work benches or manufacturing equipment, these are safety-equipped facilities specifically designed for experimental and analytical purposes.
