Listed here are a few sites to check out for vacuum equipment (including pumps and gauges) and provides. Using new respectable quality components (not backyard hose or 30 year outdated rubber stoppers!) and care in assembly with correct sealers will avoid most leaks. I don't understand how well it would have done with the outdated ugly oil. Some, like Pfeiffer and Welch,

I have not too long ago acquired a Granville-Phillips model 270 ion gauge controller through eBay ($60 whole) and am in the process of cobbling collectively a cable and vacuum plumbing to mount certainly one of my ion gauge tubes (sure, pulled out of the trash). I have never tested it decrease, but I have used it on plasma tubes and HV feed-throughs. The second Duo 1.5A had no real issues other than its base needing a paint job and

The shaft seal on the second 1402 appears nice and it goes all the way down to about 6 microns with the unique oil. The getters will kind a nice tremendous powder that can't be eliminated. They listing a large variety of vacuum equipment with prices. This gives each a load to check the filament energy provide as well as a warmup delay (on account of its filament heating) to test the interlock circuits of the ion gauge controller. However, I did find a problem and with an improvised but efficient restore it now goes down to about 3 microns after flushing and an oil change.
Friends joined her and

A particular hand-held spark coil (actually called an Oudin coil) could also be handed over suspect components of the apparatus. Spray some water (or something else) over suspect joints as the pump is running. Only hardly ever will there be a sign of an issue like a tag which reads: "This pump leaks oil all around the place".
Observe that failure of a vacuum system to succeed in a suitable stress even with a pump in most wonderful condition may be a result of many components, only certainly one of that are actual leaks (i.e., holes in the system someplace). Caution: Don't set the voltage too excessive or it's possible you'll puncture skinny glass, plastic, or rubber parts and

Water vapor is extraordinarily exhausting to pump,

However, to test the capabilities of a compressor hooked up backwards using its suction input or some unidentified stationary object that appears sort of like a vacuum pump, there could also be another. The inlet cowl gasket may be leaking barely as I eliminated the cover to verify for
