Man, does that speed up filtering! Shoulda got one at the git-go.
I don't have a Buchner flask. I'm using a 1/2 gallon Ball-Bro. canning jar. I cut a circle out of unused copper-clad circuit board the same size as the sealing lid for the fruit jar. In that I cut a smooth hole 7/8" diameter to receive the tip of the Buchner funnel. Then drilled a 1/4" hole for a 1/4" (od) copper tube. I soldered the copper tube into the circuit board. I use a stand to support the funnel - not the jar. It doesn't make a perfect seal but just enough that the pump will pull about 10" vacuum. That's enough to cut the filtering time down by 50+ %. I may install a small bleed valve on the line to help regulate vacuum if necessary.
I also don't have a catch jar for the pump yet but that's next. That will be using a 1 qt fruit jar.
I was wondering - Since there might be fumes going into the pump, what if I put about 2" of salt water in the catch Jar and extended the intake tube down to the bottom of the jar??? Then put a little stone filter on the tube (like used in a fish tank) to make smaller bubbles. Would that help protect the pump from the fumes?
