What is a laminar flow hood in Lab furniture?

A laminar flow hood, also known as a laminar flow cabinet or clean bench, is a type of lab furniture designed to create a sterile work environment. It provides an aseptic space by directing air through a filtration system, usually a High-Efficiency Particulate Air (HEPA) filter, which removes contaminants such as dust, airborne particles, and microorganisms. The filtered air flows in a unidirectional (laminar) stream over the work surface, ensuring that the environment remains free from particulates.
