Does anybody have an idea on how to make a tiny little vacuum pump on the order

110, but I can rig up a 12 volt supply if necessary.

Thoughts?

When I was in college, the chem labs used a venturi on water faucets
to create a vacuum for filtration. I've tried Google to show where to
get them, and failed.

Just a little attachment with a side barbed fitting ... good vacuum
levels, CHEAP, and appropriate for one who utilizes Bernoulli in other
ways ...

now where do I get it?
