![]() Laminar flow hoods are used in a variety of settings, including:ġ.Hospitals: Laminar flow hoods are used in hospitals to protect patients from infection. The blower is located at the back of the cabinet and produces the airflow that passes through the HEPA filter and into the working station. The fluorescent lamp is located at the top of the cabinet and helps to illuminate the working station. It needs to be turned on 15 minutes before the operation. The UV lamp must be turned on for a specific time before use and should be turned off when not in use. The UV lamp is located inside the cabinet and helps to sterilize the air inside the cabinet. The filter pad/ pre-filter must be replaced regularly. The filter pad/ pre-filter is located below the HEPA filter and helps to extend the life of the HEPA filter by trapping larger particles. You must replace the HEPA filter regularly to maintain its efficiency. The HEPA filter is located at the top of the cabinet and removes contaminants from the air before it enters the working station. Culture plates, burners, and loops are placed on the workstation. It is typically located in the center of the cabinet and is surrounded by a continuous flow of filtered air. The working station is where the user performs tasks such as handling lab samples or equipment. ![]() It's usually made of stainless steel with fewer or no gaps or joints, and the front of the cabinet is made of a glass shield. The cabinet is made of smooth, non-porous material that can be easily cleaned and sterilized. The purpose of the cabinet is to protect the user and the sample from outside contaminants. Laminar flow hood usually contains the following parts: Cabinet: The eluent air flow directly hits the operator, so any chance of cross-contamination is high. This type of cabinet is typically used for tasks that require less height, such as bacteria culture or media preparation. In a horizontal laminar flow cabinet, the HEPA filter is located at the side of the cabinet, and the airflow is directed horizontally. It is also considered safer because it reduces the chance of cross-contamination since airborne particles are less likely to escape from the work area. This type of cabinet is typically used for tasks that require more height, such as tissue culture or plant propagation. In a vertical laminar flow cabinet, the HEPA filter is located at the top of the cabinet, and the airflow is directed downwards. There are two types of laminar flow cabinets: Vertical Laminar Flow Cabinet: Laminar flow hood is also called Clean Benches Types Of Laminar Flow Cabinet Laminar Flow Hoods only protect the sample, not the user. The laminar flow hood provides an unobstructed, continuous flow of HEPA-filtered air across the work surface. The exhaust air is sucked into the face of the user by a strong blower in a laminar flow cabinet. It is designed for the aseptic distribution of specific media and plate pouring in microbiological laboratories. ![]() ![]() Laminar flow hoods are used in various settings, including medical laboratories, pharmaceutical manufacturing facilities, and food processing plants. A laminar flow hood is equipment that uses laminar airflow to protect lab samples and equipment from contamination. ![]()
