Description & Application
Description
Technical data sheet for 4-foot standard bench-mounted fume hood with vertical rising sash. Designed for general chemistry laboratory applications with ducted exhaust. The unit features a completely seamless interior liner made of chemical-resistant epoxy resin, providing superior corrosion resistance against acids, bases, and organic solvents at ambient temperature.
Application
Suitable for general chemistry, organic chemistry, and analytical chemistry laboratories. Ideal for institutions, pharmaceutical R&D centers, and quality control laboratories. Designed to handle standard chemical procedures involving volatile compounds, with provisions for electrical outlets, gas, and water supply inside the work chamber.
