What is laminar air flow/ laminar air flow hood?

A laminar air flow machine also known as laminar air flow hood. A laminar airflow is a confined workstation which is responsible for producing and maintaining a sterile workplace through filters by capturing all the particles entering the laminar flow cabinet. These cabinets are made to prevent and protect the samples (like plate pouring, or specific media) from environment having harmful bacteria and particles. It provides aseptic condition at the workplace. Laminar airflow works similarly to the biosafety cabinet with the only major difference that in the laminar air flow, only the sample is protected, not the lab personnel.

Parts of laminar flow hood:

The laminar flow hood comprises various parts:

1. Cabinet 

• The cabinet is constructed using stainless steel, ensuring a seamless design that prevents the accumulation of spores.
• It functions as an enclosure, maintaining a controlled environment within the laminar flow cabinet while safeguarding it from external conditions.
• At the front of the cabinet, there is a glass panel. In certain laminar cabinets, this glass panel fully opens, while in others, it features two hand-accessible openings for users.

2. Working Station

•  Laminar flow cabinet have flat surface inside known as working station where all the processes takes place.
• Specimens like culture plates, loops and all the necessary apparatus are placed on the working station.
• The work surface is likewise composed of stainless steel to avoid rusting.

3. Filter pad/ Pre-Filter

• Laminar airflow chamber consist filter pad just above the cabinet which permits the airflow inside the cabinet.
• This filter pad serves to capture dust particles and some microorganisms, thus preventing them from entering the cabinet's working environment.

4. Fan/ Blower

•  In laminar airflow, a fan or blower is present below the filter pad, which is responsible for circulating the air.
• This fan also directs the air towards a HEPA filter, where any remaining microbes get trapped as they pass through. 

5. UV Lamp

•  Some laminar air flow chamber have a germicidal UV lamp that sterilizes the inside of the cabinet, which is used before the initiation of operation.
• The UV lamp should be turned off approx. 15 minutes before the process to prevent any kind of contamination. 

6. Fluorescent Light

•  It is placed inside the laminar airflow hood cabinet to provide effective lighting.

7. HEPA Filter

•  It stands for High-Efficiency Particulate Air filter that plays a vital role in maintaining a very clean environment for your work.
• The air, which has already been filtered once, passes through this HEPA filter. It captures things like fungi, bacteria, and dust particles.
• This filter is essential for keeping the cabinet environment spotless and reducing the chances of any contamination.

Features of Laminar air flow hood:

• Stainless Steel Build: Laminar airflow hoods are typically constructed using stainless steel, which is easy to clean and resistant to corrosion, ensuring a hygienic workspace.
• HEPA Filtration: These hoods are equipped with High-Efficiency Particulate Air (HEPA) filters to eliminate airborne particles and microorganisms, maintaining a clean and sterile environment.
• One-Way Airflow: Laminar airflow hoods provide a continuous and unidirectional flow of filtered air, usually from top to bottom, pushing contaminants away from the workspace.
• Transparent Front Barrier: The front of the hood features a transparent glass or acrylic shield, allowing visibility of the work area while safeguarding it from external pollutants.
• Control Panel: These hoods come with user-friendly control panels for adjusting airflow velocity, lighting, and other settings.
• Noise Reduction: Some models are designed with noise-reduction features to minimize disruption to users.
• UV-C Germicidal Lamp: Many hoods incorporate UV-C lamps to further sterilize the air and the working space.
• Ergonomic Design: Laminar airflow hoods are designed for user comfort, often featuring adjustable work surfaces and armrests.

Types of Laminar air flow:

There are widely three types of Laminar Air Flow Machine, and it's important to know which one best suits your needs when shopping for one. Here's a quick reference guide to the various types of Laminar Air Flow available.

• Vertical Laminar Air Flow: A vertical laminar hood chamber is made out of a fan that is attached to the cabinet's roof. The fan draws in air and directs it downward in a vertical motion. Positive pressure is created as the air goes from the top of the cabinet to the bottom of the cabinet. Because the air is not blown directly at the user, it is regarded quite safe. A vertical laminar air flow chamber's restriction is that it requires the installation of two HEPA filters, making it rather expensive. It is commonly found in laboratories.
• Horizontal Laminar Air Flow: Input air enters from behind the laminar flow bench and is drawn in by the blower before passing through the HEPA filter. Finally, the filtered air is pumped horizontally within the chamber. Horizontal laminar air flow are huge and require a large surface area. Furthermore, because the waste air immediately blows towards the user, this sort of air flow system fails to guarantee protection to the user when handling certain pharmaceuticals, such as antineoplastic drugs. This is why vertical laminar air flow systems are chosen over horizontal laminar air flow systems.
• Ceiling Laminar Airflow: The Ceiling Laminar Airflow unit is a confinement equipment module that uses a zoned unidirectional down flow supply of air to positively pressurize and purge the working environment from potential contaminants, thereby providing enhanced sterilization work zones for maintaining process integrity and product protection. 

Uses of Laminar Airflow:

• In laboratories, laminar flow cabinets are used for contamination-sensitive operations such as plant tissue culture.
• Other laboratory activities, such as media plate preparation and organism culture, can be carried out inside the cabinet.
• Laminar air flow is used for Particle sensitive electronic gadgets are operated inside the cabinet.
• Laminar air flow is used in pharmaceutical industry on a large scale for drug preparation processes. It provides a particulate-free environment during operations.
• Laminar flow cabinets can be custom-made for specific tasks, but they can also be utilized for general lab techniques in the microbiological and industrial sectors.
