Laminar Air Flow

Laminar air flow (LAF) is a system that provides a steady, uniform flow of air in a contained space. It's used in laboratories to create a particle-free work environment for tasks like working with biological samples and semiconductors. Here are some things to know about laminar air flow: How it works LAF systems use a filtration system to emit air and exhaust it across a work surface. The filters catch all kinds of impurity particles that enter the cabinet. Uses LAF systems are used in a variety of applications, including tissue culture, media preparation, sterile handling, and PCR sample preparation. Components LAF systems often use high efficiency particulate air (HEPA) filters to ensure a continuous flow of ultraclean air. They may also include ultraviolet light lamps to kill germs and bacteria that escape the naked eye. Sterilization Before use, LAF hoods are often sterilized by wiping the working surface with 70% ethyl alcohol for 13 minutes.
