Fume hood and usage

1. What Is Fume Hood A fume hood is an important laboratory equipment which is used for ventilation purpose mostly in every research areas and hospitals. It is specially designed to limit the exposure to toxic fumes and hazardous dust. A fume hood is one of the best equipment that shields the researchers from contaminated fumes inside the laboratory. This is mandatory lab equipment that should be installed in every lab that deals with chemical and toxic applications. This is partially enclosed workspaces that exhausting fumes outside of the work area. A fume hood is a large piece of equipment and covers a large area of workspace and once it gets fixed it is hard to move because of its heavy weight. This amazing equipment comes with tempered safety glass which allows examiners to observe the students who conduct the experiment. The unit has a sash which allows toxic fumes to goes out via hood. It is very easy to use and clean unit and requires less maintenance. Mainly fume hood is made up of stainless metal and corrosive substances such as thermoplastic to protect fume hood from corrosion. The efficiency of fume hoods is evaluated by a speed of the air flow between the workplace and the sash. If the velocity of the fume hood is greater than it easily flush out the toxins gasses and vapors Generally, there are two types of fume hoods are available in market i.e perchloric acid systems and radioisotope hood systems. The first model of hood prevent the buildings or workspace volatile perchlorate salts along the exhaust systems and radioisotope hood systems are made up of stainless steel which prevents the work area from the absorption of radioactive elements. Currently, fume hood supplier in India are putting their extra efforts to make this machine more reliable and efficient.
