ATM I've got to work out how to use the Buchner filter before I start, I don't have a pump, but I do have a 3 part plastic thing (can I upload pix here?) I think maybe I have to attach it to a tap or something lol.
 
Hi bwoy.

I believe that is an aspirator. You flow water through it vertically, and it uses the venturi effect to pull a vacuum from the horizontal inlet. I think all you have to do is connect it to a water faucet, connect your vacuum tube to the horizontal barb, then turn on the water and let the vacuum slowly build.

Wicked, thanks! I thought that might be it from the mime the guy who sold it did (we didnt have a common language).
 
I dont think that's going to pull enough suction to get your stuff through a buckner filter as the paper used is pretty thick and clogs pretty much instantly. I had to do some major pumping to get my stuff filtered and I went through a lot of filters anyhow.

OK So I'll have to buy a pump. Thanks for the tip.
 
I second that. I think hand pumps work better with buchner funnels.
