A fume hood Malaysia, also known as a fume cupboard, is a ventilation device that is made to prevent prolonged hazardous or toxic fumes, dust, or vapor exposure. The device is large and there are two types of it: ducted and ductless.
It is essential lab equipment because the goal is to protect laboratory users from inhaling toxic chemicals, protect users from an explosion, spill containment, and so on. Apart from that, fume hoods also protect the product/experiment, and protect the environment.
It is recommended to use a fume hood when working or there’s a chance the experiment will produce a substance that passes the limit value of less than 50 ppm. This device protects users when they are working with flammable, water-reactive chemicals, pyrophoric, and corrosive components.
Certain fume hood limitations include:
Yes, there are! Some experiments do require specific fume hoods that are specially for certain chemicals.
This type of fume hood is able to spray water to wash the exhaust duct, the wall, and the baffle to remove any remaining perchloric acid that has accumulated. Use for high concentrations of or any operation that involves perchloric acid fumes.
This type of fume hood is highly resistant.
A ductless fume hood that is used to protect laboratory users and the environment from hazardous gas that is generated into the air.
It is used to support lead bricks or blocks so it is made out of stainless steel liner that is coved and an integral stainless steel countertop.
This fume absorbs fumes through a compartment filled with plastic shapes, which is then washed with a scrubbing medium. Then, the fumes are disposed of in a neat manner.
Provided with an internal wash system that washes the internal parts of the unit so that dangerous chemicals would not accumulate over time.
