What is a Laminar Flow Hood?

If you want to shield your workers from all the toxic and harmful chemicals abound in your laboratory then it is vital that you should fit your laboratory with laminar flow hoods. Laminar flow hoods are in fact mandatory as safety equipment. They must be installed in those laboratories where chemical and toxic researches are done and where different such activities are performed and the laboratory facilities need to be used daily. In this article you will learn about the vitality of having laminar flow hoods and what they basically are.

What are lab Fume Hoods Used for?

You can keep the toxic fumes out from the working space of your laboratory as this can protect your workers. The fume hoods will all be partially enclosed within the spaces that would be ventilated and they would also help you to exhaust the fumes from the inside of your laboratory right to the outside. It will not take a lot of space also inside your laboratory.

The designs of the fume hoods:

The tempered safety glasses are all positioned at the back and also on the sides with the tall viewing windows that allow better visibility to perform several experiments. The laminar fume hoods also have specific sashes that can get used for doing loading, cleaning activities. They will allow better air flow also.

The efficiency of laminar flow hoods:

The efficiency of the laminar fume hoods will be measured with the speed in which air flows and then will cross the work surface and the sash. This will be measured in the units of feet per minute and if the velocity of the laminar hood is more, then the toxins will get flushed out at a quicker pace.

The different designs for laminar hoods: 

The laminar fume hoods will prevent exposure of any toxins and poisonous vapors. The different hoods are specifically designed to work with different velocities and used for several technological applications and chemicals.  There are some different types of laminar hoods also like the radioisotope laminar hoods, the chlorine acidic systems. The vertical laminar flow hoods and the horizontal laminar flow hoods and so on.

Other types of laboratory fume hoods:

These days there are at least five standard models of fume hoods and these are all used for different conventional, auxiliary, ductless, bypass and other requirements of variable air volumes. The conventional types would be used to maintain constant volumes of the exhausted air and would not take into account the height of the sash. If the main concern you have is to save energy then you can use auxiliary fume hoods. There are ductless fume hoods also which re-circulate the air back in the laboratory if the system of filtration has been done.


The laboratory and laminar flow hoods are vital equipment that are required for installing in laboratories so that they can ensure people’s safety when they work inside laboratories. Hopefully, the information mentioned in this article will have helped you.
