I’ve never once taken my sintered disk off and cleaned them (well once I never will again)…one reason they NEVER see powders…I have 2 filter plates w drop in ring plate combo to make 1 filter plate 2bplates. I load both w 2-4um papers. Then I have the exact same double paper filter again 2-4um…then filter plate filled w tampon Tek…then 5,I’m and 1um welded disk. Powders make it past the first plate pretty good, the next plate barely, never makes it through the 1um tampon so when the disk get something it’s a liquid only. I’ve taken them off tried to clean them nothing ever comes off. Proper Prefilters and save yourself some time!
I even have a column to hold the solvent not suspended in material now after it goes through the material while waiting to get through the light crc
And I still wanna add the .22um from waxplug in column above the collection so it’s not inside the collection pot
Take it from me just use some extra Prefilters and u want have powders on ur disk, crc done the right way, if I had hot material though I was remediating then I would clean the system throughout before use
