Make sure to buy a rubber cork and the right sized filter paper for use with these funnels, as both of these things will be needed to operate your funnel properly.
Rubber corks can also be drilled out to fit bigger stems, just as bigger filter paper may also be cut down for use in smaller funnels. You can also enhance your filter flask with our black rubber filter aid!
