What is a Fume Hood and How Does It Function?

Anyone who has been in a laboratory environment knows that proper ventilation and fume control is absolutely essential. Without it, the lab would be full of toxic fumes and smoke that would damage your lungs and compromise your health. That’s why you need a functional fume hood and we at Scientific Lab can provide you with one.

What Does It Do?

Fume hoods are some of the most important apparatuses in the laboratory and without it, you can’t conduct some of your more risky experiments. Here’s a brief explanation on what this device does to help you:

    • It protects you from inhaling smoke, fumes, and toxins from chemicals, fire, biological matter, etc, that’s present in the lab.


    • The fume hood would also protect sensitive and volatile elements from the environment and the basespresent in the lab. This ensures delicate samples and microorganismsaren’t corrupted, and show true results at the end of the experiment.


    • These hoods can be used to create a unique environment for your samples or cultures. You can add specific air filters to alter the composition of the air within the hood.


  • This device can also be used to contain explosions and spills because it’s always made from resilient and durable materials.


Fume hoods are lined with different materials to provide the best environment for experiments. The most commonly used materials are:

  • Epoxy Resin
  • Phenolic Resin
  • Stainless Steel (Square Corner)
  • Stainless Steel (Coved-Corner)
  • Fibre-reinforced Plastic
  • Cement Board

Different materials provide different advantages. For example, epoxy or phenolic resin is great for a wide range of experiments. Square-corner steel is great for heat-resistance and durability. Coved-corner steel is great for biohazard and decontamination.

Types of Fume Hoods

There are many kinds of hoods that serve different purposes. You need to think about what kind of experiments you would conduct in your lab before you choose one:

  • Bench Mounted Fume Hood –The bench mounted hood, can be placed on a bench and is compact. It’s ideal for small labs with limited capacity. It’s often used to remove gas, chemical mist, and vapours in normal lab conditions. This is the more affordable option and is widely used in a number of school and college labs. It can handle low-hazard conditions easily and has a consistent exhaust volume.


  • Walk-In Fume Hoods –These hoods are large and create a contained environment where researchers and scientists and walk in and conduct their experiments. These come in standard heights of 4ft by 6ft which can be customized according to your requirements. They’re made from sturdy materials that can withstand lab conditions and are roomy enough to offer considerably maneuverability.

Good fume hoods will keep your lab environment healthy and sanitized, which is absolutely essential for your health. If you intend to experiment with chemical, toxic biological, or radio-chemical materials, a hood and a hazmat suit would protect you from negative consequences
