The results shows that the perimeter flow is typically in the form of a narrow shealth of higher velocity air acted as a protective barrier that prevents the re-entering of contaminated air into the laminar flow.

The laminar flow device which is working with 100 fresh air should be absolutely used in Type 1A operating rooms. Standard models are available to measure as little as 02 SCCM 59 E-06 SCFM to as much as 2250 SCFM of air flow at standard conditions. Air exiting the filter media in a unidirectional flow that is essentially particle-free.

Flow characterized by erratic or violent movement. All seeds need to be sown on growth medium in a sterile laminar flow hood to reduce the chance of contamination. Set the growth chamber light intensity at 130 μmolm 2 s with lights on for 24 h.
