These 56mm filters fit perfectly in a CoorsTek 60240 porcelain buchner funnel. I could not get them to fit with Stonylab porcelain buchner filters. They work best with cold water extractions, from my experience, but i have used water alcohol mixtures, solvents such as chloroform, and vacuum filtration of small amounts of concentrated acids, and they seem to hold up well. They work well for filtering fine charcoal, and other fine particulates. I use them almost daily!
It's good filter paper, performs exactly as expected.
