Syringe filters seem very impractical. I've used them in an analytical lab and they clog easily. When dealing with a lot of fat/lipids I don't think they would work well.

Vacuum assisted filtration with scientific filter papers work best. When selecting a pump, you need to consider getting one that can handle solvents or add a coldtrap to extend pump lifetime. Here's a link to a complete set.

If you don't have very much product and are not interested in spending the money, you can try a hand pump. I've never used one but found it through a quick amazon search.
