![]() ![]() Clean benches can be used for certain clean activities, such as the dust-free assembly of sterile equipment or electronic devices, and they should never be used when handling cell culture materials or drug formulations, or when manipulating potentially infectious materials. Fan system is isolated from work area make it ideal for a vibration free applications such as microscope. These devices only provide product protection. Free-Standing Vertical Laminar Flow Hoods Can be used with any standard workbench. Horizontal laminar flow or vertical laminar flow “clean benches” are not biosafety cabinets these pieces of equipment discharge HEPA-filtered air from the back of the cabinet across the work surface toward the user, and they may expose the user to potentially hazardous materials. Vertical laminar flow station is a free-standing laminar flow booth or a mini cleanroom with one or two fan /filter units (FFU) on the ceiling. Vertical flow hoods, on the other hand, provide significant protection to the user and the cell culture. The flow can be horizontal, blowing parallel to the work surface, or it can be vertical, blowing from the top of the cabinet onto the work surface.ĭepending on its design, a horizontal flow hood provides protection to the culture (if the air flowing towards the user) or to the user (if the air is drawn in through the front of the cabinet by negative air pressure inside). ![]() Laminar flow hoods protect the working environment from dust and other airborn contaminants by maintaining a constant, unidirectional flow of HEPA-filtered air over the work area. Vertical Laminar flow hood / bench provides a HEPA filtered airflow across the work area that protects the sample from airborne contamination.
