Laminar Fume hood

What is Laminar Fume Hood?

A laminar fume hood is an enclosed workspace that keeps things clean by filtering out particles from the air. It uses HEPA filters to trap any contaminants. Thus, the hood makes sure the work area stays free from dirt or dust. These hoods are mainly used for handling materials that aren't harmful to people.

At Swastik, our laminar fume hoods fall under the "process protection" category. This means they’re designed to protect your samples from contamination. The hoods blow clean, filtered air (thanks to the HEPA filter) over the work surface in a steady flow. This creates a clean, controlled environment, ensuring your samples stay safe and free from outside particles.

Note that regular fume hoods pull air in and exhaust it outside. Whereas, a laminar fume hood blows filtered air across the workspace. This creates a clean environment and helps prevent contamination.

Laminar fume hoods have a smooth and one-way airflow. The air moves in a single direction either horizontally or vertically throughout the work surface. This flow of air helps keep airborne particles away from the work area and stops cross-contamination of samples. Thanks to the HEPA filter which traps tiny particles. Laminar fume hoods are of two types, Horizontal Fume Hood and Vertical Fume Hood. A horizontal hood lets air to blow from the back of the unit toward the user. On the other hand, the vertical hood lets air flows downward. Indeed, both designs offer the same protection but the choice depends on the specific needs of the lab.

Laminar Flow Fume Hood Working & Applications

A laminar flow fume hood is frequently used for handling lab samples that need to be as sterile as possible but are safe for inhalation. In an LFH, air is pumped throughout the work zone in a single direction after passing through the HEPA filters that are mounted in the hood. The clean air stream ensures the safety and protection of the materials by removing any steam, smoke, or dust that may be produced during various activities.

Laminar fume hoods, however, should be understood to be distinct from biosafety cabinets. LFHs release good air from the unit’s backside across the workspace and toward the operator, exposing them to chemicals. Again, a laminar flow fume hood, such as a bio safety cabinet, only offers protection for the materials being performed on and does not safeguard the operator from breathing in particles released by the lab samples.

Laminar fume hood can be used for a wide range of scientific operations and activities that require clean, dust-free, abacterial air conditions, such as executing cell culture studies, making sterile pharmaceutical goods, or putting together sterile equipment. However, these devices are not suited for handling infectious substances.

How does a Laminar Fume Hood work?

When using a fume hood, air is drawn into the chamber with the help of a blower from away from the user. The facility exhaust system is used by the fume hood to cleanse the air before venting it outside. An alternative is to use a fume hood to filter the air, get rid of any harmful fumes, and then circulate the air inside the space. Most fume hoods have gauges or sirens that can alert the user to inadequate airflow and the possibility of being exposed to dangerous vapours.
