JFT Fume Hood A fume hood is a critical piece of equipment commonly found in laboratories, designed to protect users from hazardous fumes, vapors, and dust. It functions by providing a ventilated workspace, where harmful substances are drawn away from the user through a built-in exhaust system. Fume hoods are typically equipped with a sash that can be adjusted to minimize exposure, while allowing for safe manipulation of chemicals. The airflow is carefully controlled to maintain a constant flow, ensuring that contaminants are effectively contained. Regular maintenance and proper use are essential to ensure their effectiveness, making them vital for safe laboratory practices, especially in chemistry and biology settings.
