Horizontal Laminar Air Flow

As their name indicates, horizontal laminar flow hoods direct air horizontally. Air is pushed through a HEPA or ULPA filter positioned on the back wall and moves forward across the work surface until it exits the enclosure.

n laboratories, a laminar air flow cabinet is used to create a sterile atmosphere for activities like plant tissue culture. This is because the presence of pollutants in the environment may readily impact these processes.
