Get to Know About the Laminar Flow Hood with HEPA filter
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.
