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. These devices only provide product protection. They are suitable for equipment or operations requiring more vertical space. These workstations feature HEPA filters that are 99.99 efficient on 0.3 micron particles (ULPA grade filters are available as an option). Vertical laminar flow hood designs save floor space and are easy to set-up on existing standard lab benches. Our Laminar Flow Workstations are Top Quality, Industrial Duty These units are manufactured to endure almost any environment. 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. Our Laminar Flow Workstations are proudly manufactured in the USA. Vertical flow hoods, on the other hand, provide significant protection to the user and the cell culture. 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. 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.
