Up until recently I've always filtered by whatman syringe. This is obviously time consuming so have recently looked into bottle top filtering.

I bought some "complete units" which were plastic and not too great. I've also just bought a "Buchner"-style glass filter kit where you put paper in the top? I don't think these are the best for filtration though?

Can anyone advise if this is ok? What's the best sort of paper to use to match syringe whatman 0.2um filtering or am I looking for the wrong thing here?

Thanks
