Celite vs medium frit filter

Just want to know if celite 545/celatom fw60 +whatman 1 filter paper are a necessary filtration aid when using activated carbon powder to decolor if I’m using a medium frit buchner funnel (10-15 micron pore size)?

Active carbon can permanently adhere to frits, or so it is said, so I wouldn’t try it without the celite… also it goes right through my 25 micron paper filter but seems not to make it through a 1um glass filter.


You won’t need the paper just the celite 545 on the frit should suffice.
