They have no moving parts, but have molded-in or otherwise fabricarted louvers ( as the term was applied to these pertrubances on automobile engine hoods. the idea is to increase circulation of moving air, a form of practical streamlining.

if the carr's index for any type of powder is 10% than the flow property of the powder will be excellent.

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.
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.
difference between laminar air flow & reverse laminar air flow
This question is its own answer. The flow patterns in laminar flow are laminar.
Do you know the difference between a laminar flow hood and a biological safety cabinet? Laminar Flow Hoods * provide product protection only and must not be used when working with any form of biohazard or chemical hazard * any potentially infectious aerosol that is created will lead to exposure of the operator and the environment * horizontal-flow clean-air bench used for cell cultures can expose the researcher to aerosols of allergenic or infectious materials. * vertical-flow clean-air bench also blows air out into the roomBiological Safety Cabinets * provide personnel and environmental protection and commonly product protection * infectious agents must be used in a biological safety cabinet NOT a laminar flow hood
Laminar flow hoods and hepa filter must be certified every 6 months. The type of environment that a laminar flow hood provide ISO 5, which is formerly known as a Class 100 area.
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.
Its used to avoid the spreading of fumes and gases when conducting an experiment resulting in a gaseous reaction.
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.
