Get to Know About the Laminar Flow Hood

Laminar flow hood is described as airflow in which the direction and velocity of all of the air inside a given region are uniform.

A laminar flow hood is what?

Examples of laminar flow hoods are biological safety cabinets and clean benches. They are HEPA-filtered laboratory enclosures that are precisely aimed. Some of these hoods guard against contamination of objects put on the work area. Others shield the user from pollutants in the working environment. Laminar flow hoods, also known as cell culture hoods or tissue culture hoods in laboratories are frequently used to work with biological samples, semiconductors, or other sensitive materials.

Early in the 1960s, the laminar air flow principle was created. Since it literally shaped how air safely moves in many generations of laboratory enclosures, it is still extremely relevant for contemporary labs. There are several types of laminar flow hoods available today. They all employ this kind of unidirectional airflow to help preserve sterility, minimize cross-contamination, and reduce turbulence, despite the fact that they vary based on the science conducted inside.

Laminar flow hoods maintain a continuous, unidirectional flow of HEPA-filtered air over the work area to shield it from dust and other airborne pollutants. The flow may be vertical, blowing from the top of the cabinet onto the work surface, or it may be horizontal, flowing parallel to the surface.

A horizontal flow hood may protect the user or the culture, depending on its design. On the other hand, vertical flow hoods offer both the user and the cell culture great security.

Pristine Benches

Clean benches with horizontal or vertical Laminar flow hood do not function as biosafety cabinets; instead, they expose users to potentially dangerous substances by discharging HEPA-filtered air across the work surface toward them. All that these gadgets do is safeguard the products. When handling cell culture materials, medication formulations, or other potentially infectious materials, clean benches should never be utilised. Instead, they should only be used for specific clean activities, such as the dust-free assembly of sterile equipment or electronic devices.

Using a Laminar flow hood from Planet-of-Mushroom, mushroom cultivation is done. The laminar airflow system is employed in these settings to ensure that there are no contaminants or particles anywhere in the working space. A laminar airflow system provides continuous, uniform air flow in both direction and velocity. Hoods or cabinets with laminar air flow enable unidirectional airflow in a constrained area.


Our Laminar Air Flow Cabinets are containers made to channel HEPA-filtered air at a constant speed and direction. Cross-contamination is avoided and sterility is maintained thanks to this unidirectional airflow. Cabinets or hoods for laminar air flow are often made entirely of stainless steel with no connections or gaps. Since there are no gaps, it is simple to stop pollutants from entering and gathering.


How do they operate?

A filter pad, a fan, and a HEPA are all part of our laminar air flow hood. Air is drawn through the filter pad by the fan. The filter pad has the dust sucked in. The HEPA filter removes pollutants including germs, fungus, and micro particles from the pre-filtered air. The work area is filled with sterile, germ-free air, allowing all tasks to be completed there without concern for contamination. The laminar airflow cabinet comes with one or more HEPA filters. The system is completely enclosed on all sides, and positive air pressure is kept constant.


Based on the work surface design, operator safety, type of work, clearance requirements, and process location, a laminar airflow system can be chosen.


Cabinets with the horizontal laminar flow: In horizontal cabinets, the filter is placed in the back, behind the desk. This technology allows air to move horizontally over the desk, toward the user, and out of the workspace. These cabinets are simple to install and place. The horizontal airflow aids in preserving a clean environment.


Vertical Laminar Air Flow Cabinets/Hoods: The filter is top-mounted and placed above the workspace in vertical cabinets in the Laminar flow hood from Planet-of-Mushroom. In this technique, the work surface is sterilized by air that is blown vertically onto it from the top of the cabinet. The working environment is then ventilated through the perforations in the cabinet base.
