do you have a manifold you could use? I hook up 8 flasks at a time to one vac, or two 30gal bel-art funnels to a single vac. How much material are you running through?

Here you go, I'm not positive about the size of the filter you're going to need/want. I would imagine 150 mL would be good but you could go bigger or smaller depending on what you want. The bigger you go the buchner funnels get expensive fast.
