So I should be using more sintered discs than just one?
What micron is it? 1 should work
Sometimes have to double or triple the paper to get a tight seal. Need a ring not a clamp in the filter stack

I use a celite cake above 11um filter paper, then 6um paper on a 5 um sintered disc, then 2 micron filter paper in the last filter stack

Cool thing is none of those powder dissolve in tane, so if you are ever wondering if you are getting pass through you can test by running your system at the pressure you would usually run at with just a powder. Any powders will be visible

Iâd love for that to be fat, for your sake. Take some of that silica/fat and put it in ethanol. If it melts itâs fat, if itâs silica itâll stay the same
Actually, doesnât silica melt in etho?

If you do have passthrough its an easy fix. Dissolve, chill and refilter. Silica seems to swell in cold tane

this is key. I like to wash my cake with 5 mic in place then run smaller filters below on the real run. always cleaning equipment between.
