You'll need: - Metal Coat Hanger
- Pliers
- Pliers
- Tape
- #64 Rubber Bands
Instructions: - Cut off the lower portion of the coat hanger so that you have one long straight piece
- Bend completely in half with pliers, tape open end
- Bend in half again, but only enough to fit the bottom of a 60ml syringe
- Bend up both sides roughly 0.75in from #3 - it should now look like a mix between a V and a U, and should fit a 60ml syringe
- Bend down both sides roughly 1.0in from #4 - it should now look like an upside down W
- Pull center apart just enough to fit the end of the syringe
Notes: - Seems to work best with 10cc air pocket
- 16 rubber bands is more than enough.

Or, $3 for a caulk gun.

A+ for creativity.
Damn, the syringe filters that I had need a lot more pressure than those rubber bands provided. What's up with that? .20 micron just too much of a bitch?

I use .2's with the caulk gun method. Just leave enough air in the back (around a 1/3 of the syringe). Put it in a vice pointing downward, and attach the vial to the gun somehow. I used rubber bands. Give her a pump or two and come back in a bit. Takes a long time with .2's, but you do not have to apply the pressure. I've used .45's and they are at LEAST twice as fast, but you do not get the same level of sterility. With the fact that you don't have to do labor to use them, I don't know why anyone would use .45's anymore. As mranak already knows though....a bottle top/stericup setup is much better than syringe filters. Especially the ones that have a draw line and you do not have to open them to the air to fill your vials.
