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.
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.
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.
Sintered NdFeB magnets are made by compacting and heating a mixture of neodymium, iron, and boron powders. This process results in a very strong and high-performance magnet. Bonded NdFeB magnets are made by mixing NdFeB powder with a polymer binder, which allows for complex shapes but with lower magnetic properties compared to sintered magnets.
I used a funnel to transfer the liquid into a bottle.

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.
A funnel cloud may be called a condensation funnel or simply a funnel.
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.

Brembo are the original fitment EBC brake pads work just as well and are half the price. Sintered pads are required for the front and the original fitment for the rear is non sintered.
