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.

What is the Role of laminar air flow chamber in sterilization of mushroom?
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.
Why a manometer is attached with the laminar air flow unit?
manometer is important because it shows the working condition of HEPA filters
Horizontal vs vertical laminar flow hood?
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.
Why you use 70 percent ethanol in laminar air flow chamber?
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
How do you do the cleaning of laminar air flow?
Hi, For cleaning LAF you first wash your hands with alcohol. Now take a cotton and dip it in 70% alcohol and wipe in on LAF properly in each and every corner. Also rub the cotton into the holes or floor if the LAF is vertical air flow type. Clean the UV tublights and ordinary tubelights with alcohol. If there is any stain of cultural media on the floor which can not be removed by cotton then take a glass slide and scratch it with slide. After cleaning with alcohol properly now shuttdown the screen and on the UV light for atleast 20 minutes and before 5 minutes of starting your work putt of the UV light. NOTE: Never stand in front of the LAF when UV is on it can cause mutation to you.
Difference between laminar air flow and reverse laminar aire flow?
difference between laminar air flow & reverse laminar air flow
What are flow patterns around a stationary object in laminar flow?
This question is its own answer. The flow patterns in laminar flow are laminar.
Why is no obstruction important for air flow techniques?
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.
When was Laminar Flow - album - created?
Laminar Flow - album - was created in 1979.
What can be used to define laminar flow?
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.
What is the effect that radius changes have on the laminar flow of a fluid?
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.
What are the basic differences between laminar air flow and biosafety hood?
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
What is the assumption of steady flow process?
Flow is Laminar.
How is turbulent flow different from laminar flow?
gago..
Where can someone purchase a Laminar flow hood?
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.
What are the differences between horizontal and vertical laminar flow hoods?
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.
Who invented laminar air flow?
Bernoulli was the first guy to study it some 250 years back - laminar fluid flow that is.
