A ducted fume hood. Most fume hoods for industrial purposes are ducted. A large variety of ducted fume hoods exist. In most designs, conditioned (i.e. heated or cooled) air is drawn from the lab space into the fume hood and then dispersed via ducts into the outside atmosphere. [5]
A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level.
The laboratories contain biotechnology equipment including real-time PCR instruments, Plate reader, Opentrons liquid handling robots, flow hoods, non-ducted fume cupboards, -80, -20 and 4C storage, incubators (static/shaking), centrifuges (1ml-50ml refrigerated), and bench space [4]
Ducted kitchen hoods are the most common and a primary type of kitchen hood. As the name suggests, a ducted kitchen hood has a duct that is used to process and expel any smoke that is generated on top of the kitchen hob. Large sized duct hoods are widely used not just in homes but also in commercial restaurants and communal kitchens too.
Biosafety cabinets, although designed to contain bioaerosols, can also be used to contain nanomaterials. Biosafety cabinets are designed to contain bioaerosols. However, common biosafety cabinets are more prone to turbulence. As with fume hoods, they are recommended to be exhausted outside the facility. [11]: 25–27
Fume and smoke collectors are used to remove sub-micrometer-size particulates from the air. They effectively reduce or eliminate particulate matter and gas streams from many industrial processes such as welding , rubber and plastic processing, high speed machining with coolants, tempering , and quenching .
