What is a sintered funnel?
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.
What is a Hirsch Funnel and how are they used?
They are used for vacuum filtration to separate crystals, or solids, from a liquid. Usually a neoprene adapter is used to fit the funnel to a flask that is attached to some sort of vacuum. A filter paper is used to make sure no solids get through, or clog, the funnel. Typically, it is advised, that hot solutions are not used in vacuum filtration because the reduced pressure will cause solvents to evaporate, and the solid will precipitate out; causing the funnel, and pores of the filter paper, to clog.
What kind of filter paper is used in sintered glass crucible?
Sintered glass crucibles typically use a type of filter paper known as "sintered glass filter discs" or "sintered glass filters." These filters are made from finely powdered glass that is sintered to form a porous structure, allowing for the filtration of fine particles while maintaining chemical resistance. They are commonly used in laboratory applications for filtration, drying, and other processes where durability and purity are essential.
What pore size is related with porosity 2 of sintered glass filter?
The pore size is the average 100 micrometers.
What glasswear does the filter funnel rest in?
Though there are exceptions, it is usually an open-top, glass funnel.

What sintered glass crucible made of?
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.
What pore size does porosity 4 sintered glass have?
Porosity 4 sintered glass typically has pore sizes ranging from 4 to 16 micrometers, with an average pore size of around 8 micrometers. The pore size distribution can vary depending on the specific manufacturing process and conditions used to produce the sintered glass material.

What is sintered glass and its porosity?
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.
What is a glass funnel used for in a laboratory?
ok
How should glass evidence be collected processed and handled in a crime scene investigation?
the glass should be picked up by tweezers and the technician should be wearing gloves. the person collecting glass should put it in a plastic evedence bag and brought to the lab.

What helps to mix liquids?
Well, thats an easy one... Its a funnel!
