The pore size is the average 100 micrometers.
A sinterd funnel is simply a funnel with a built in filter. The filter is sintered, I think that this means that small particles are compressed together (and heated ?) to form a single piece of material with many small holes. The sintered funnels I use are made of glass, a link to some images is below (not mine). http://curlyarrow.blogspot.com/2008/01/how-to-clean-your-sintered-funnel.html I have also used sintered polyethylene and sintered stainless steel for filtering.
To avoid contamination, especially in chemical analysis.
Though there are exceptions, it is usually an open-top, glass funnel.
You can filter it off using a sinted glass crucible, fine filter paper, a vacuum pump and a side-arm flask. If you don't have that sort of equipment: a filter funnel, filter paper and a conical flask should do.
A jar or beaker. See the Related Questions to the left for more information.
Sintered glass is a glass mesh used for filtration. It can be used instead of filter paper, and in fact is preferable to filter paper. Its other advantage is that it is permanent so you can get various different pieces of glassware with sintered glass in it e.g. an enclosed filter suitable for filtration under nitrogen. As for the porosity.... Porosity of sintered glass is labelled by integers from 0-5 (viz. 0, 1, 2, 3, 4, 5) where 0 has a pore size of 160-250 micrometres and is considered course filtration, that is fluid will pass through it quickly and some finer solids will pass through. Whereas, porosity 5 has a pore size of 4-10 micrometers so even ultrafine solids will not pass through and liquids will drop through. I hope this is clear, makes sense and is helpful.
Sintered glass crucible is a glass mesh used for filteration. It can be used instead of filter paper, and in fact it is preferrable to filter paper. Sintered glass crucible must be cleaned then dried to constant weig befoe it can be used to filter out precipitates such as silver chloride.

yes.... it is an answer for porosity....
No, glass is not porous
Because of the gravity of the earth....
crucibles are prefer over filter paper because filtration by crucibles are efficient as that of filtration by filter paper and Gooch crucible is preffered due to its suction force that make the process of filtration faster

There are several places in the body that act as filters. The most common example would probably be the glomerulus of the nephron in the kidney, but lymph nodes, the spleen, the liver, and even the walls of blood vessels act as filters.
Not to visible light.
Ordinary glass will filter out UV rays by itself. So you will get the combined filtering of the glass and the ozone reducing the UV ray intensity.
Baljet reagent freshly prepared (95 ml 1% picric acid + 5 ml 10% NaOH) mixed immediately before use and filtered through a sintered glass funnel.
