Tim V. had an interesting article in the Feb-Mar Wine Maker, talking about vacuum degassing. He missed one inexpensive and very effective piece of vacuum-generating equipment.
When we needed vacuum in the lab we had faucets with venturis attached. The water flowing through the faucet pulled a vacuum in the venturi, which we attached by tubing to whatever we needed to pull the vacuum on. They will give about 26" Hg vacuum or better, have no moving parts, require no effort on the part of the user, and don't consume very much water. Best of all, if the wine foams up to the point of coming out of the top of the carboy, it just enters the water stream and goes down the drain.
I'll look around and see if I can find a small lab sized unit that will screw into a standard faucet. Maybe George can put together a kit with the venturi, some tubing, a stopper, and a piece of rigid tubing to go through the hole in the stopper.
George - If you make a bunch of money off of this idea, just pay me in store credit!!!
