Why glasswares are wrapped with paper?
Glasswares are wrapped with paper before autoclave. After autoclave the glassware is taken to laminar flow hood in sterilized conditions where it is unwrapped. So wrapping is done to avoide contamination during taking the glassware from autocalave to laminar flow hood.
How soon can you use a laminar flow hood after you turn it on?
30 mins
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.
The laminar flow hood should be left operating continuously If it is turned off.it should not be used until it has been running for at least?
30 minutes
What characteristic is important when preparing an IV admixture in a Laminar Flow Hood?
Sterility, solubility and stability are all important when preparing IV admixtures.
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.
What should be the size of HEPA filter for laminar flow hood?
0.2 Micron

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.

Which solution is recommended for cleaning a laminar flow hood?
isopropyl alcohol

What is the safety of laminar flow?
A laminar flow prevents the inappropriate circulation of air within a hood where cells or bacteria are being cultured. This prevents contamination and also insures the safety of the worker
What is the underlying mechanism of a laminar flow hood in microbiology?
The underlying mechanism of a laminar flow hood in any application, including microbiology is that a roughly non-turbulent flow of air is more effective at preventing cross contamination of materials in the hood and having that air go through a high efficiency filter first is effective in preventing contamination by microbes and other items from outside the hood.
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 horizontal laminar flow hood used for?
Its used to avoid the spreading of fumes and gases when conducting an experiment resulting in a gaseous reaction.
