Horizontal laminar flow hoods.
Horizontal laminar air flow bench diagram.
With horizontal laminar flow clean benches hepa filtered air flows horizontally across the workspace directly toward the user see diagram at end of this chapter.
Laminar flow hoods are designed to protect samples and parts from particulate contamination.
Horizontal flow hoods are most commonly used with the more costly vertical flow hoods being reserved for agents that may produce an environmental hazard e g.
Air is drawn through a hepa filter and blown in a very smooth laminar flow towards the user.
What is laminar flow bench.
Laminar flow hoods are used to control airborne contamination of sterile products during their extemporaneous preparation.
The work area is bathed by positive pressure horizontal laminar flow air that has passed through a high efficiency particulate air hepa filter.
