A Step-by-Step Guide to Safely Using Laminar Flow Cabinets
In laboratory settings, maintaining a sterile environment is paramount to the success of your research
March 26, 2026
Air Science laminar flow hoods provide ISO Class 5 clean air to protect sensitive products, samples, and processes from airborne particulate contamination. Available in both horizontal and vertical airflow configurations, our laminar flow cabinets create a sterile, particulate-free work environment for laboratory, pharmaceutical, medical device, electronics, and research applications where product protection is essential.
Designed for reliability, energy efficiency, and exceptional filtration performance, our laminar flow hoods feature Air Science Multiplex™ ULPA Filtration Technology and are manufactured in the USA to deliver consistent clean-air performance across a wide range of critical applications.

No. Laminar Flow Workstations are designed to circulate clean, filtered air across the work surface to protect delicate processes from airborne contaminants. The filtered air exits from the front of the work surface toward the user. Both vertical (downflow) and horizontal (across flow) versions provide the same level of protection using HEPA filters at the top or rear of the cabinet. Cabinet selection depends on the size of the work surface and the vertical space desired.
