Re: [neonixie-l] Pressure and kind of gas in nixies
My aparature for filling nixies is rather primitive. I have my own glass diffusion pump (1 stage), rotary pump, my own glass Penning manometer, glass valves and glass bottle with neon. I have a lot of glass bottles and two metal bottles with Penning mixture. Poland is very strange country. I rescued it from trash!

Re: [neonixie-l] Pressure and kind of gas in nixies
Hi, oh, I started reading myself into the topic in November, but I had several difficulties on the way. I am currently writing down my experiences so far, I will create a new section for that on my website, but it will take another two weeks or so. I have not managed to create a glow lampe or something yet, but I am confident that I will be able to do so in the next month. I work with soda lime glass and a primitive soldering torch that you cal buy in any hardware store, and I even managed to create simple pinch seals that are vacuum tight. I have some Neon here in a pressure bottle, but I have some vacuum problems in my setup. The pump is a two-stage rotary pump that goes down to 5E-3 mbar, but I still need a needle valve to insert the Neon gas into the tube and a proper tube connection. If you count the buts in my sentences you can see that there is a lot of stuff to figure out :-) It is very exciting, but also quite time consuming.

Re: [neonixie-l] Pressure and kind of gas in nixies
About the neon, I am in touch with a salesman from Messer group, he offered me probably the same bottle - Cangas 1l 12 bar bottle, 12 litres of neon, 50 eur + VAT. They offer pressure regulator what can be evacuated for 200eur... and simple one for 100 eur.. Are you sure You will be able to use this cheaper one?

Re: [neonixie-l] Pressure and kind of gas in nixies
Neon is quite expensive; about 50EUR for 12 liters. It is a pressurized bottle at 12bar, so it almost looks like a can of hair spray ;-) You should be able to do better than that if you don't need that much neon. http://www.montroy.com/catalog/main/itemdetail.app?item_no=NEON It's 0.9 liter of neon at atmospheric pressure for about US$20. This way, you can get away without a pressure regulator or needle valve. Fuse the flask onto a bit of tubing on your manifold with two stopcocks near each other*. Once you're pumped down, spin the one closer to the flask a half turn (which will quickly open and close it again). This will trap a little bit of neon between the two stopcocks, at a pressure somewhat below atmosphere (this will drop as the neon is used). Then meter the neon into the manifold with the second stopcock. Since you're partitioning out maybe half a milliliter of neon at atmospheric pressure or less into a manifold that's considerably larger, even if you just leave the second stopcock open, you'll already be down to something in the useful range. If you want more pressure, close the second stopcock and spin the first again. This is not a precision setup by any means, but for those of you who'd like to play with neon on the cheap, it's a reasonable way to get going without spending too much money. * These glass flasks have a thin glass seal to keep the neon in. The usual way to open one is to put a clean piece of ferrous metal in the tubing before sealing it up. Then open both stopcocks and run your vacuum pump until the manifold is pumped down good. Then close the stopcocks and use a magnet to yank your metal chunk over to break the glass seal. If your metal chunk isn't clean, your neon will be contaminated. - John -- You received this message because you are subscribed to the Google Groups neonixie-l group.

Re: [neonixie-l] Pressure and kind of gas in nixies
Nice solution, but I am afraid I would destroy the flask and let the neon go out ;-) If I were from US I would try it, but because I am from EU where we have nothing like this or if we have, it is several times the price in US, I will use a cangas bottle :-( The solution with magnet is very nice!
