Explain the Laminar Flow Hood - Biological Safety Cabinet?
It illustrates the laminar flow hood. As you can see, this biological safety cabinet contains HEPA (high efficiency particulate air) filters which remove, 99.97% of the particles having size more than 0.3 µm. Air is forced through these HEPA filters and a vertical column of sterilize air gets formed across the cabinet opening. It prevents the contamination of room and the workers from microorganisms. The cabinet also has UV light, which is switched on about 15-20 minutes earlier before and after the work is finished to make the working surface sterile. Laminar flow hood is employed in the research labs and in industries, for conducting assays, preparing media and culturing microbes.
Note: (i) Never switch on the UV light while working in the laminar chamber.
(ii) Air flow should be on, at the time of working in the chamber.
