    Filter recommendation fr Buchner Funnel 125mm

    Hey guys,

    i hope you can help me: i'd like to use a Buchner funnel with 125mm in diameter - actually i can't find some fitting filter papers (with fitting diameter yes, but i'm not quite sure about the resistence)

    Thanks in advance

    Try the pvdf ones. I have run them with the 90mm width and they were great. They are bit pricey but worth it in my experience. You can do a google search and find them just make sure you get the .22 ones. They should be able to handle all solvents as well in case you do something with guaiacol or EO (I personally would not inject EO as it eats stoppers what does it do in the body but my personal preference).

    Bigmills turned me onto them. I know REHH runs a buchner as well and has some good input.

    just one last question: do you buy the hydrophobic or hydrophilic version? Does it matter for us?

    I like the hydrophobic ones. I feel they are the best for everything we are trying to do.
