Vertical clean benches, also known as laminar flow clean benches or laminar flow hoods, are specialized laboratory equipment used to create a clean and sterile work environment for conducting procedures that require protection from airborne contaminants. Vertical clean benches use HEPA (High Efficiency Particulate Air) filters to create a laminar flow of filtered air that flows vertically over the work area. This airflow protects the work surface and items within the bench from particulate contamination. Vertical clean benches are used in a variety of microbiology, cell culture, sample preparation, electronics assembly, industrial, clinical, and pharmaceutical applications. In summary, vertical clean benches are essential tools in laboratories where maintaining a sterile and particle-free environment is critical for conducting sensitive experiments, handling delicate materials, or ensuring the integrity of biological cultures and samples.
