Fume hood units designed for procedures involving perchloric acid feature a water-wash system in the ductwork and are often built from marine grade stainless steel or rigid polyvinyl chloride, [43]: 36 Because dense perchloric acid fumes settle and form highly reactive perchlorate crystals, the internal baffles of the fume cupboard and ductwork ...
Fume hood Glove box 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 .
Despite their similar appearance, a laminar flow cabinet should not to be confused with a fume hood. A laminar flow cabinet blows unfiltered exhaust air towards the worker and is not safe for work with pathogenic agents, [ 2 ] : 13 [ 3 ] while a fume hood maintains negative pressure with constant exhaust to protect the user, but does not ...
A function analysis diagram (FAD) is a method used in engineering design to model and visualize the functions and interactions between components of a system or product. It represents the functional relationships through a diagram consisting of blocks, which represent physical components, and labeled relations/arrows between them, which represent useful or harmful functional interactions.
Microscope: used for visualising minute structures, including microbes: Bunsen burner or spirit lamps or candles: source of fire / heat Ultracentrifuge: used to separate particles dispersed in a liquid according to their molecular mass: Electrophoresis apparatus

A distillation setup using a Liebig-type condenser (the tilted double-walled tube at the center). A liquid (not visible) in the flask at left is heated by the blue mantle to the boiling point.
The article currently states "Fume hoods (fume cupboards) are generally available in 5 different widths; 1000 mm, 1200 mm, 1500 mm, 1800 mm and 2000 mm. The depth varies between 700 mm and 900 mm, and the height between 1900 mm and 2400 mm." Firstly, shouldn't it use centimeters, not millimeters?
