A clean bench is a specialized piece of equipment used in laboratory and cleanroom settings to create a controlled, clean environment for conducting scientific experiments or handling sensitive materials.

Typically, a clean bench features a work surface enclosed by glass or acrylic panels with a built-in HEPA filter system to provide a constant flow of purified air. This airflow helps to prevent contamination of samples or materials by capturing and removing airborne particles.

Users are required to sterilize and clean the clean bench regularly to maintain a high level of cleanliness and prevent the buildup of dust, debris, or microbial contaminants. Cleaning procedures may involve wiping down the surfaces with disinfectant, replacing filters as needed, and ensuring proper airflow and performance of the equipment.

Overall, a clean bench plays a crucial role in ensuring the integrity and reliability of laboratory experiments and processes by providing a sterile and controlled environment for work to be carried out effectively.
