When air moves through a given space in both unified direction and velocity, it is said that it has achieved laminar air flow. It comes from the word a laminaa that means that the air moves as one uniform body. A laminar air flow cabinet, also known as a tissue culture hood, clean bench, biological safety cabinet, or simply laminar hood, is a work surface enclosed in a boxlike structure mechanized to flood the inside of the enclosure with clean, sterilized air flowing in a laminar manner. It looks something akin to a fume hood , but works the opposite way. Whata s the difference between a fume hood and a laminar airflow cabinet A fume hood sucks air out of the work area. A laminar airflow cabinet sucks clean air into the work area. This airflow has to be laminar in nature, because normally air flows in a very irregular nature. Normal a that is, turbulent air flow creates lots of eddies and vortices that wreak havoc on any sterile-air environment. They can gather and deposit particles from outside air on your beloved hard-worked culture and screw up your whole result. Thus, we drown the work area in air that moves as one body, in uniform velocity and direction, so that eddies and vortices dona t form. That is exactly what laminar airflow is. The basic idea of a laminar airflow cabinet is to provide a safe, sterile, filtered air environment. It uses the following parts: Enclosure Work Surface Prefilter/filter pad Blower/fan HEPA Filter UV Lamp These parts come together to make a laminar airflow cabinet. Using the blower or fan, the product sucks in room air from the front or top of the product. The air first passes through the prefilter or filter pad, which captures large dust particles from the air. Then it goes through the HEPA filter, which filters out all the fine particles and microbes. That filtered air then pours into the enclosure and washes over the work surface, clearing it of any suspended particles and microbes. You can use the UV lamp to further sterilize the work area by bathing it in deadly rays. The air flow is kept laminar by way of constructing the product carefully, so that all parts of the air inside the enclosure flows in straight lines parallel to each other, in the same direction. The airflow can be horizontal or vertical in manner, depending upon what should be the purpose of the sterile hood a to keep the sample safe or to keep the user safe. Vertical Laminar Airflow In this more common, compact type, the air flow is from top to bottom. The filters and the fan/blower is mounted on top of the product. The air can flow out the front of the enclosure after hitting the work surface, or the work surface can be perforated to let the air pass through and feed back up top into the primary filter.
