What is a vertical laminar flow hood used for?
Vertical laminar flow hoods are best for applications that require the use of large equipment on the work surface as the workspace is taller and larger with less turbulence caused by the vertical airflow. Vertical laminar flow hoods are often favored for many applications due to their resemblance of cleanroom setups.
What is most commonly used to clean a laminar flow hood?
Swab the bottom edges and lower back corners. Then clean the work surface, back to front, left to right. Repeat this cleaning process using a sterilizing agent such as USP grade sterile 70% isopropanol.
