What can I buy as an alternative to lab filters?

  1. Jan 17, 2013 #1
    I have tried using coffee filters in the past but they seem to be too thick. The ones I have are 300 g / m^2. Just looking on wikipedia they say filters actually made for chemistry are 80 g / m^2. What other paper can I buy in a rush, in a pinch, from a place like Wal-mart that will be a suitable filter? Thanks.

    I suppose I should mention the specific experiment we are doing this time is making casein glue from skim milk.

    what about stacked paper towels?

    By stacked I mean 2 or more paper towels for proper thickness.

    You also might be able to get some silk as an alternative.

    Would cheesecloth work for your application?

    Thanks for the suggestions, the coffee filters actually ended up not posing a problem this time.

    Paper lens wipes (sans methanol). Get the ones that leave no lint.

    A ball of cotton stuck in the funnel.
