Laminar Flow and Fume Hoods FAQs

Laboratory hoods serve a number of critical purposes in the lab environment.

Product protection from particulate contaminants in the lab environment, including microbes

Such hoods, often called laminar flow workstations or clean benches, use a flow of HEPA-filtered air to prevent influx of viable and non-viable particles into the enclosure and to sweep away any contaminants generated by the work process.

Protection of personnel and lab environment from substances generated inside the enclosure

For fume containment, laboratory fume hoods use a ducted ventilation system that maintains negative pressure. Where ducting is impractical, ductless hoods are also available for removal of non-hazardous contaminants (fumes or particles), using either HEPA or activated carbon filters.

Protection of product, operator and environment

Biological safety cabinets combine aspects of both hood types: a laminar flow of micro-filtered air and negative-pressure containment of bio-hazard fumes.

Laminar Flow Hoods

Laminar flow hoods (also called laminar flow clean benches) force air through a HEPA or ULPA filter to create a clean work area free of nearly all contaminating particulates, including bacteria, mold spores and many viruses. These hoods use a vertical or horizontal airflow design. Both provide excellent protection of products from particulates and cross-contamination, but do not protect the operator or environment.

So why choose one over the other? Vertical laminar flow hoods (VLF Hoods) require less floor space, but more overhead clearance. In addition, a sash at the front of the VLF hood provides a barrier between air exiting the hood and the operator’s face. VLF hoods create turbulent air flow when air strikes the work surface, requiring sterile work to be performed above the work surface.

HLF hoods minimize air turbulence (and particle backflow) on the work surface except where equipment disrupts the horizontal airflow. However, they direct the airflow directly at the operator’s face and require more depth to accommodate placement of the fan filter unit at the rear of the hood.

Fume Exhaust Hoods

Laboratory fume hoods draw air from the environment through the opening of the hood, allowing environmental contaminants into the work area. Thus, lab fume hoods do not offer a sterile environment or product protection. Instead, chemical fume hoods are designed to protect the operator from dangerous or irritating fumes and powders generated from work performed inside the hood.

In ducted fume hoods and canopy fume hoods, air passes out of the hood through a duct leading to an in-house ventilation system that contains and/or neutralizes hazardous materials.

In ductless fume hoods, fans draw exhaust air through a series of filters that remove irritating substances before release back into the room. Since these filters are not 100% efficient in removing all substances, ductless fume hoods are not advised in the presence of biohazards; however, they provide a convenient, cost-effective solution for operations involving irritating but non-hazardous fumes in facilities where an in-house HVAC system cannot be accessed.

Biosafety Cabinets

Biological Safety cabinets combine design aspects of both laminar flow and fume hoods. Filtered air is directed downward onto the work surface and then travels into a plenum through openings on the front and sides of the hood. Depending on the classification of the biosafety hood, some percentage of air is recirculated through a HEPA filter while the rest is directed out of the hood through an exhaust system. Thus, biosafety cabinets offer operator, environmental and product protection.

These laboratory safety cabinets (sometimes called IV hoods or compounding hoods) are ideal when preparing sterile medications such as chemotherapeutic agents that may pose a risk to the operator.

BSCs, BSLs, and ISO Classes

When it comes to working with hazardous or potentially infectious material, protecting personnel must be the primary concern. However, offering personnel protection does not have to come at the cost of risking product integrity. Class II BSCs provide protection to both personnel and product simultaneously. They maintain an ISO class 5 clean work area for product manipulation, while ensuring that exhaust air is filtered and ducted out of the environment. Thus, a class II BSC is the ideal solution when working with moderately hazardous material and both personnel and product safety are required.

Critical Environment Solutions

Terra's mission is to help customers in highly regulated industries transform the world with critical environment solutions that improve health, safety, performance, and yields. These environments may comply with stringent UL, ISO, IEST, ASTM and OSHA standards and local requirements.

BioSafe® WhisperFlow Hoods: One-Piece Design With Seamless Tracks

BioSafe® Whisper Flow Hoods feature a one-piece design free of cracks or crevices that harbor microbes and contaminants. Surface are easy to wipe down, resistant to alcohol-based cleaners and harsh biocides.

HEPA-Filtered Reverse Flow Fan Unit

High Efficiency Particulate Air (HEPA) Filter Fan Unit provides clean micro-filtered air, shown in reverse-flow hood that captures contaminants generated in the work area for safe cleanroom release.

Recessed LED Lighting Illuminates Work Area

Laminar flow hoods include long-lasting LED lighting to illuminate the work area. The LED strip is flush-mounted for easy disinfection.

Versatile Removable Panels

Removable side-panels increase the versatility of your hood by improving visibility plus simplifying equipment access. The side-panels are lined with foam gasket and slide into the hood’s frame for a simple yet effective seal. Each panel is easily removed to simplify cleaning and disinfection.

Tilt-Up Sash

Tilt-up sash enhances laminar airflow and prevents air from blowing directly at the operator’s face. Static-dissipative PVC material resists chemicals and eliminates particle attraction from static charges.

Integrated Status Indicator Light

Operation status indicator (OSI) light glows continuously when hood is plugged in and turned on to confirm filtration unit is operational. The OSI blinks when the unit is plugged in but switched off.

BioSafe®: Terra's Ultimate Cleanliness Rating

Terra's BioSafe products are designed for the most critical applications: no gaps and crevices where microbes colonize, rounded corners for easy disinfection, won't produce contaminants during sterilization, and exceeds cGMP, IEST, ASTM and ISO 14644-1 requirements.
