When it comes to controlling airborne contaminants in a laboratory setting, a laminar flow hood is an essential piece of equipment. These hoods work by creating a unidirectional airflow that helps to keep the work area free of particles and contaminants. However, with so many options on the market, finding the best laminar flow hood for your specific needs can be a daunting task. In this article, we will discuss some key factors to consider when shopping for a laminar flow hood and highlight some of the top models available today.
Types of Laminar Flow Hoods
There are two main types of laminar flow hoods – vertical flow hoods and horizontal flow hoods. Vertical flow hoods are the most common type and are typically used for applications that require a clean work environment, such as cell culture work or microbiological testing. Horizontal flow hoods, on the other hand, are often used for applications that require a larger working area, such as electronics assembly or packaging.
When choosing between vertical and horizontal flow hoods, it is important to consider the specific needs of your laboratory and the type of work that will be done in the hood. Vertical flow hoods are generally more compact and easier to use, while horizontal flow hoods offer a larger working area but may require more space in the laboratory.
Key Features to Look For
When shopping for a laminar flow hood, there are several key features to consider to ensure that you are getting the best possible hood for your needs. Some of these features include:
– HEPA Filters: High-efficiency particulate air (HEPA) filters are essential for trapping particles and contaminants in the airflow. Make sure that the laminar flow hood you choose comes equipped with HEPA filters that are capable of filtering out particles as small as 0.3 microns.
– Airflow Velocity: The velocity of the airflow in a laminar flow hood is another important factor to consider. Higher airflow velocities can help to prevent contaminants from entering the work area, so look for a hood with a velocity of at least 90 feet per minute.
– Material: The material of the hood itself is also important. Stainless steel laminar flow hoods are durable and easy to clean, making them a popular choice for many laboratories.
