Horizontal clean benches, also known as horizontal laminar flow benches or simply laminar flow benches, are another type of clean air equipment used in laboratories and industries. Unlike vertical clean benches where air flows vertically over the work area, horizontal clean benches create a laminar flow of filtered air that moves horizontally across the work surface. This airflow provides a clean and sterile environment for working with materials and samples that require protection from airborne contaminants. Horizontal clean benches are used in a variety of microbiology, cell culture, sample preparation, electronics assembly, industrial, clinical, and pharmaceutical applications. In summary, horizontal clean benches are essential tools in laboratories and industries where maintaining a sterile environment is critical for handling biological samples, conducting sensitive experiments, or assembling delicate components. They ensure that work surfaces remain clean and free from airborne contaminants, thereby enhancing the reliability and integrity of laboratory procedures and processes.
