Different Type Of Laboratory Fume Hoods and Laboratory Glove Boxes
A laboratory fume hood can also be called an exhaust hood, it is a ventilation system which is designed to limit the exposure of hazardous and toxic fumes, vapours and dust. This is the primary function of a laboratory fume hood to act as a ventilation unit. The secondary function involves safeguarding or protecting against chemical spill over and unwanted runaway reactions. It also acts as a physical barrier and helps in preventing fires.
There are basically two types of Laboratory Fume Hoods one is Ductless Exhaust Fume Hoods and the other one is Ducted fume hoods
Ductless Exhaust Fume Hoods ventilate and remover of hazardous chemical fumes or vapours through activated charcoal filters. Thus, allowing the safe indoor release of exhaust. The HEPA / ULPA filters provide the clean and particle-free environment.
Ducted fume hoods, on the other hand, ventilate to the outer side and provide the more protection against chemically dangerous fumes. Now let’s look at the different variations in Ductless Exhaust Fume Hoods and Ducted Hume Hoods.
Ducted Fume Hoods – High Clearance
High clearance construction laboratory fume hoods also referred as ducted exhaust hoods or chemical fume hoods are available in different sizes from 18″ to 72″ width, they include spill chemical tray/ polypropylene work surface. These are ideal for applications which require exterior ducting for exhaust and require full visibility of the fume hood interior. These fume hoods have two optional fan modules with adjustable air speed. Ducted fume hoods are ideal for soldering or chemical processing that requires the removal of potentially hazardous fumes from low-level corrosive vapours. These can be made of Polycarbonate, non-dissipative PVC and ESD PVC construction materials.
Ductless Fume Hoods- Portable
Carbon & HEPA filtered enclosures are also known as filtered fume hoods. These are ductless laboratory enclosures that remove hazardous fumes, vapours and particles from the laboratory. These ductless containment hoods are available in sizes of 24″, 32″ width and can be used for removing chemical fumes, dust particles, pharmaceutical powder and solvent or acid vapour.
Ducted Fume Hoods – Polypropylene
Polypropylene laboratory fume hoods are very durable and chemical resistant are turnkey ventilation system designed for applications that require exterior ducting for exhaustion. These chemical fume hoods are bottomless that can be placed over the standard size worktables. These laboratory exhaust hoods can be equipped with fan module. These are a great choice in cases in which chemical processing requires the removal of potentially hazardous fumes.
Ducted Fume Hoods- Stainless Steel
Stainless steel fume hoods have good resistance power to a wide range of chemicals and act as excellent moisture and heat resistants. They can be decontaminated and cleaned easily and they are ESD safe that makes them suitable for electrostatic-sensitive applications. The sash is static dissipative PVC and work surface is optional and removable. They come with or without exhaust blower unit depending on your need. Their Primary function is to provide personal protection against toxic fumes, vapours and dust but is not compatible with some acids.
Containment Ventilated Enclosures (CVE)
Containment ventilated enclosures are also known as HEPA filtered exhaust hood or powder containment hood. These are good for powder handling, such as non-sterile hazardous drug compounding in pharmacies. They can be used to protect the user from particles at the same time while weighing, mixing, preparing, compounding, dispensing, administering HDs or low to moderately hazardous powders.
Ductless Down flow Workstations
The down flow hoods are constructed from polypropylene and have a removable stainless-steel work surface that can be easily removed and cleaned. They collect powders or vapours through perforations on the work surface. These are available in 24”, 32”, 36” width. They are perfect for handling pharmacy drugs & medicines, chemical latent print development, solvent and chemical preparations.
Check out the air lock features of Closed Laboratory Glove Boxes
It is a known fact that most of the laboratories in both commercial and domestic sectors used quality closed loop filtration globe options in an effective way. It is widely recommended for people to check for quality glow boxes because it plays a crucial role for people to improve the results on a regular basis. Most of the Laboratories have made it mandatory for people to use Laboratory Glove Boxes while examining a biological sample from time to time.
Why used Closed Loop Filtration Glove Boxes
Closed loop filtration boxes have been used widely in large-scale Laboratories because it helps them to perform necessary tests in order to find accurate results on a regular basis. Some of the quality closed-loop filtration boxes provide an easy option for people to work in a quick span of time. Closed loop filtration glow boxes are widely used because it provides a convenient option for people to adjust the temperature and features based on the requirement in an effective way.
Features of Closed Loop Filtration Glove Boxes
- Effective air lock features – Air lock features plays a crucial role for every user because it helps them to adjust the glove box to find accurate results in a quick span of time. It is highly recommended for people to check for equality Laboratory Glove Boxes because it helps them to use the airlock features for a long span of time without compromising on the performance effectively.
- Constant temperature adjustment – It is necessary for people don’t look for a constant temperature adjustment while working on a Laboratory Glove Boxes because it helps them to find accurate results in a quick span of time. Most of the people would prefer to use a quality glove box because it helps them to adjust the temperature without causing any contamination of the sample in an effective way
- Healthy option – It is evident that using quality Laboratory Glove Boxes plays a vital role while working in the laboratory because minor contamination could cause infection to the people from time to time. It is necessary for people to stay healthy and away from infections because of biological samples, as it could decrease the productivity and cause a lot of health problems in an effective way.
- Low-contamination – It is necessary for people to check for the contamination levels while working in both commercial and domestic Laboratories on a regular basis. A Laboratory Glove Boxes provides efficient protection to biological samples without contaminating in an effective way.
