we can also use 100% ethanol or pure ethanol but as it has been tested that 70% is sufficient to kill all the cells and spores of microbes so use this
The laminar air flow chamber is a way to provide a sterile work area. This lowers the possibility of contamination while working with your cultures or fungi.
manometer is important because it shows the working condition of HEPA filters
laminar flow Smooth, orderly movement of a fluid, in which there is no turbulence, and any given subcurrent moves more or less in parallel with any other nearby subcurrent. Laminar flow is common in viscous fluids, especially those moving at low velocities. Its used to avoid the spreading of fumes and gases when conducting an experiment resulting in a gaseous reaction.
UV light iddivided in to three. UV-C wave length from 100nm to 280nm. UV-B 280nm to 315nm and UV-A 315nm to 400nm. The wave length of 254nm (UV-C) is giving maximum germicidal activity and it is not too irritating.
Bio, fun stuff, right

Laminar Airflow describes the flow around an object such that the air stays "attached" to the surface. At higher airspeeds, the air become detached and turbulent. Thus a laminar flow chamber is one where airfoils or model airplanes are tested at low airspeeds and especially airspeeds less than Mach 1.0.
difference between laminar air flow & reverse laminar air flow
This question is its own answer. The flow patterns in laminar flow are laminar.
The laminar flow hood depends on the laminar air flow to sweep away pathogens from the hood. If there is obstruction, the laminar air flow pattern will be disrupted. The laminar air flow will then change to turbulent air flow.
Laminar Flow - album - was created in 1979.
Laminar flow can be defined by the help of Reynold's number that can be determined by conducting experiments. A Reynold number <=2000 indicates that the flow is laminar.
Laminar flow is the free-flowing blood in the middle of the vessel. Therefore, larger the radius of vessel, more the laminar flow. Smaller the radius of vessel, lesss the laminar flow. Laminar flow is directly reltated to the radius of a vessel.
Flow is Laminar.

Laminar flow hoods can be found through ebay's website. Companies NuAire, Terra Universal, and Air Clean Systems all offer their own laminar flow hoods (also called laminar flow closets and tissue culture hoods) on their official websites.
In a horizontal laminar flow hood, the laminar air flows towards the outside (i.e. towards the worker). There is hence no protection to the worker and it is not suitable for cytotoxic drug preparation. In a vertical laminar flow hood, the laminar air flows downwards from the top, providing more protection for the workers. Vertical laminar flow hoods are hence suitable for preparing cytotoxic drugs.
