Lab Equipment: Why A Laminar Flow Cabinet Is A Must!

Information may not be reliable

A laminar flow cabinet is a type of equipment used to reduce the level of air turbulence and other airborne particles to prevent unwanted contamination. Laminar flow cabinets can be used in any lab or clean room, such as medical research facilities, drug manufacturing plants, engineering environments, and academic laboratories. It facilitates the production of quality products by removing particulates like dust, aerosols, and spores from a room's environment.

Laminar flow cabinets are essential for preventing cross-contamination between different areas within labs or companies. They can also be found in hospitals to ensure high sterility levels during surgeries without using costly sterilization equipment. Laminar flow cabinets are also used in various industries, such as aerospace, dentistry, electronics, aerospace, and pharmaceuticals.

Types of Laminar Flow Hoods

Most laminar hoods come in two configurations, Vertical and Horizontal airflow hoods. They both differ in the direction of airflow through them.

Ø  Vertical Laminar Flow Hood- In a vertical laminar flow hood, the air is channeled through the air outlet ports, travels across and across the hood, and exits through the air outlet ports. This type of laminar flow hood can fit a smaller space and can be used for small-scale lab work.

Ø  Horizontal Laminar Flow Hood- In a horizontal Laminar Flow Cabinet, the air is channeled into the lower part of the hood over an area from which it flows out into a separate outlet port. This type of laminar flow hood can also fit in a smaller space and has more versatility than the vertical laminar flow hood.

How Laminar Flow Hoods Work?

Like other production environments, Laminar flow cabinets have air filters that are used to reduce particle sizes by other methods, such as electrostatic or vacuum filtration. To understand how these filters work, it is necessary to understand the airflow process and how laminar flow hoods operate.

ü  Noise from air moving through the laminar flow hood is divided into three parts- one part flows through the laminar flow hood, one part travels through the filter, and another part travels through the last filter.

ü  The noise from the first filter is larger than the other two parts. This is because air flows through the filter at a greater rate than the other components.

ü   For the second filter, its noise level can be calculated by adding up its airflow and speed and its distance from the laminar flow hood.

ü  This data will allow you to calculate any other part of the system to forecast how much turbulence will be generated when this happens in real-world conditions.

A laminar flow cabinet is a modern necessity for many industrial and lab works. It provides a containment-free environment and provides a safe and hazardous-free workspace for the workers.
