Dear Scientists,
I would like to consult you about the issue that I recently faced with that. I am planning to do 0.2 µm filtration of silica nanoparticles in water with a size of around 50 nm. I tried different filter types (cellulose, PTFE, PES, Nylon, hydrophilic, etc), but unfortunately, non of them worked out. Could you please recommend to me which filter type (material) I have to select to easily pass the sample through it without issue?
Best regards,
Ali

Hanieyeh Etezadi Thanks for your kind reply. I would like to pass a sample very well dispersed in water through 200 nm filter and centrifugal filter doesn't work as I don't want to purify it. Regarding the nylon syringe filter, I tried that as well and didn't work out :(
