https://tube.loping.net/videos/watch/f821e9db-b3c1-458a-ae7f-f3e0bc3668dd My high-vacuum Penning gauge has been having some problems lately. The last time that I "fixed" it, I used lead solder to create a crushable metal seal between the parts of the gauge body. Eventually the rosin leaked out and probably caused contamination within the gauge. I bought some Indium wire on eBay to replace the metal seals after cleaning the gauge with a bead blaster, sandpaper on glass, and lots of alcohol swabs.
