I have some crude I treated with T5. Having a little trouble getting all the T5 out of the oil. I’ve filtered it over 1-3 micron paper on a buchner about 10 times and I’m still seeing a few grains in the mix I just can’t filter out.
As @thesk8nmidget sugest I also think something is passing treu the sides
T5 is self filtering media so after the second run treu same cake it should not happen even with 25 mic paper
Try adding a (non-silicone) retention ring that fits snugly along the internal border of the funnel so that the sides of the funnel aren’t letting things slip.
Reqlly depends on your buchner, you could use one of those cheap filter plate rings and it would work great.
Those filter plate rings are more standard in size, because their outer diameter is the same as a triclamp pipes inner diameter. Buchners sre manufactered at all sizes in differrnt thicknesses and can have slight imperfections with the funnel itself.
Hi ObxLabs, in order to remove fine powder like particles you need depth filtration. Not paper, to easy to slip through. Please see attached literature on depth media. We carry this type product (will fit in the Buchner you have), so if you have any questions, please let me know. TFibrafix-FS-eFNA.pdf (378.7 KB) Thanks, Greg
