Hi Jens, I actually mean system with metal to metal seals, sorry ;-) But even these parts with KF/NW flanges are expensive.. I am going to build one from glass, all parts are easy to collect and I will learn just glassblowing, what will be useful for nixies too.. Dalibor 2012/5/23

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

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!
