A laminar flow hood is a crucial piece of equipment in many laboratory settings. Its main function is to create a clean, sterile work environment by filtering out particles and organisms from the air. There are two main types of laminar flow hoods: vertical and horizontal. In this article, we will discuss how to choose between the two.
Vertical laminar flow hoods are designed to direct air vertically downward toward the work surface. This creates a controlled environment where the air constantly moves away from the operator and toward the vents at the bottom of the hood. Vertical hoods are typically used for applications where protection from airborne contamination is critical, such as microbiology, pharmaceuticals, and electronics.
When choosing a vertical laminar flow hood, it is important to consider the size of the work area and the type of materials to be used. Many vertical hoods come with a built-in blower, which can help maintain a consistent air flow. However, larger hoods may require an external blower for sufficient air movement.
Horizontal laminar flow hoods are designed to direct air horizontally across the work surface. The air flows from back to front, creating a barrier between the operator and the materials being worked on. Horizontal hoods are typically used for applications where protection from contamination is important but not critical, such as plant tissue culture, cell culture, and media preparation.
When choosing a horizontal laminar flow hood, it is important to consider the size of the work area and the type of materials to be used. Horizontal hoods typically have a smaller footprint than vertical hoods, making them ideal for labs with limited space. However, they may not provide the same level of protection against airborne contamination as vertical hoods.
In summary, when choosing between vertical and horizontal laminar flow hoods, it is important to consider the level of protection required for your application as well as the size of the work area and the type of materials you will be working with. Vertical hoods are ideal for applications where protection from airborne contamination is critical, while horizontal hoods are more suited for applications where protection from contamination is important but not critical. Ultimately, the choice between the two will depend on your specific needs and requirements.
