vetokaappi

A vetokaappi, also known as a fume hood or fume cupboard, is a piece of laboratory equipment designed to protect the user from inhaling hazardous vapors, fumes, or dust. It consists of a cabinet with a movable sash that encloses the workspace. When the sash is lowered, it creates a seal that draws air from the laboratory through the cabinet and exhausts it outside, typically through a ventilation system.

The primary function of a vetokaappi is to contain and remove airborne contaminants generated during experiments or procedures. This is achieved by maintaining a sufficient airflow across the opening of the hood, which pulls any released vapors or particles away from the user's breathing zone and into the exhaust system. Proper airflow is crucial for effective containment.

Vetokaapit are commonly used in chemistry, biology, and other scientific fields where potentially harmful substances are handled. They are essential for ensuring a safe working environment and preventing exposure to toxic or corrosive chemicals. Different types of vetokaapit exist, varying in design and features, to accommodate specific laboratory needs and the types of hazards being managed. Regular maintenance and testing of the ventilation system are important to ensure the continued effectiveness of the vetokaappi.
