Introduction to Laboratory Fume Hoods


A fume hood is laboratory equipment used to get rid of the fumes and toxins from the workplace. Our company is known for producing the most cost-effective and economical equipment which provide a complete combination of protection, safety, reliability, and a great efficiency. They are sold in a wide range of industries worldwide, e.g. pharmacy, medicine, research, electronics, etc.

What are laboratory chemical fume hoods?

A laboratory fume hoods (also called laboratory fume chambers) are designed to serve the specialized industrial purposes.

A tabletop form , also known as, a fume cupboard is an enclosed ventilation machine used to minimize exposure to poisonous vapors and toxic chemicals in the chemistry lab. Our laboratory hoods range from large to small sizes, depending on the requirements of customers.

How do they work?

A bench top of our facilities has an exhaust fan installed on the top of the cabinet to draw the airborne chemicals and then diluting them through the ducts. Enough volume of air should be available in the room to extract hazardous vapors from the air.

Specifications of lab Fume Hoods include

  • A front window sash made up of tempered glass that acts as a shield for the operator against hazardous aerosols.
  • A stainless steel sink installed inside the hood which is resistant to the vapors produced in the work area.
  • Lateral surfaces of the work chamber made of tempered glass provide additional visibility.
  • Auxiliaryexhaustfan
  • All the control devices are located on the front panel preventing any contact of an operator with the hazardous environment.

Special Fume Hood

These fume cabinets are used for purposes beyond the scope of general fume chambers. Theycanbedividedintoseveralcategories, forexample:

  2. Walk-in. These are mainly used for large pieces of testing appliances.
  3. Canopy. They are suitable for processes that produce more heat and nontoxic gases that have an upward direction.
  4. Radioisotope. Their main purpose is to handle radioactive experiments. Such a hood is designed with shields that are resistant to poisonous aerosols and chemicals.

FinalStatement

  • To ensure safety, the fume hoods must be operated with extreme care.
  • The person must know how to operate it accurately.
  • He should make sure that the hood is properly tested before using it

  • They should be used when dealing with chemicals
  • The operator must wear a lab coat and gloves to avoid any bodily harm
  • No extra materials such as paper should go inside the ducts because it might obstruct air exhausting.
  • The appropriate type of lab hood must be bought keeping the type of techniques, budget, safety levels, and energy consumption levels in mind.
