Ducted fume hoods in the past were the only option available to labs and account for only one component of a total lab ventilation system, which includes a series of ducts, blowers and filters running through the entire building.
Conventional ducted fume hoods often describe the traditional, less elaborate fume hoods that have a constant air volume. Face velocity is inversely proportional to the sash height unless a by-pass is in place.
The following benches measure 36 inches or less in overall width and are ideal for personal use or small spaces.
The following fume hoods are available in 48 inch width.
The following fume hoods are available in 60 inch widths
72 inch fume hoods are a common standard size and are suitable for many applictions.
For large applications or multiple users you may wish to consider 96 inch or larger fume hood.
Variable air volume ducted fume hoods maintain a constant face velocity regardless of the sash position by employing a closed loop system that is constantly measuring and adjusting the amount of air being exhausted.
Canopy Ducted Fume Hoods are typically used when the area that needs ventilation is too large to fit inside a regular hood. They are suspended above the work area.
Ductless Fume Hoods are single enclosed units that require no duct work or fixed installation. They remove fumes, vapors and particles by filtering them through a combination of HEPA and carbon filters and exhausting them safely back into the lab air.
Free standing ductless fume hoods are single enclosed units that require no duct work or fixed installation.
Benchtop Ductless Fume Hoods offer a very convenient alternative to traditional ducted fume hoods as they can be placed on rolling carts and moved around the lab as required or permanently mounted to a bench.
Th following benches measure 36 inches of less in overall width and are ideal for personal use or small spaces.
The following fume hoods are available in 48 inch widths.
The following fume hoods are available in 60 inch widths.
72 inch fume hoods are a common standard size and are suitable for many applications
For large applications or multiple users you may wish to consider a 96 inch or larger fume hood.
Portable Ductless Fume Hoods are designed to go anywhere science takes you in the field or for temporary hood needs in the lab.
Downflow workstations direct air in the opposite direction as most other hoods; they push it down. Air containing powders or chemicals with high molecular weights are swept into the base of the workstation, protecting the lab worker by removing it away from their breathing zone.
Laminar flow hoods provide clean air via a HEPA filter to the lab bench space and a constant air flow out of the work area, which prevents surrounding room air from entering. The air flowing out of the hood also suspends and removes contaminants and particles creating clean air spaces.
The following laminar flow benches measure 36 inches or less in overall width and are ideal for personal use or small spaces
The following laminar flow benches are available in 48 inch widths
The following laminar flow benches are available in 60 inch widths.
72 inch laminar flow benches are a common standard size and suitable for many applications.
For larger applications or multiple users you may wish to consider a 96 inch or large laminar flow bench.
PCR enclosures are designed specifically to provide a Class 5 work space for PCR experiments by moving HEPA filtered air downward. What makes them unique is a UV light that eliminates DNA and RNA contaminants.
Erlab Captair Flex XLS Models
Ductless filtration fume hoods with large internal volume
Designed to perform non-pathogenic handlings, the new range of CaptairBio PCR enclosures has been created for handlings involving a high sample cross contamination risk such as sample preparations before thermocycling, Post PCR DNA sequencing revelation / separation, in vitro fertilization, cellular cultures, vegetal biology, preparation of sterile solutions.
New enclosure design - from 80 cm to 1,8 m –equipped with a powerful UV decontamination preventing any handling from cross contamination risks.
The design of the new modular filtration column equipped with an HEPA H14 filter guarantees 99,995% filtration efficiency for particles larger than 0,1 microns (according to the EN1822-1 standard, MPPS method).
The air entering the enclosure is free of any external contamination and provides an ultra clean work atmosphere.
The modular filtration column technology also allows the use of optional carbon molecular filter offering an additional protection of the enclosure from gase pollutants present in the laboratory ambient air which may interfere with sample integrity.
With their very low energy consumption from 70W to 150W, the annual running cost of these units does remains very low and allows a faster return on investment.
Ideal for applications such as non-pathogenic cell cultures, in-vitro cultures, microbiology, homeopathic preparations, electronics, and optics. These workstations feature HEPA H14 filters to provide an ISO Class 5 work environment. The HEPA H14 filters guarantee 99.995% filtration efficiency for particles larger than 0.1µm.
