I still don't understand why you buy neon in that form. Seems really expens= ive. You could get a compressed neon cylinder for about the same price and = I think similar purity, but the quantity would be 100x. I know you don't wa= nt pressure but you can use a regulator to take it down to low pressure. So add storage of high pressure cylinder, plus needing regulator, then plum= bing from regulator into gas system. Then add the hazard of accidental ove= rpressure into the manifold system blowing things apart. I could be talked into some sort of mylar bag temporary container, filled f= rom the cylinder and then joined to the manifold. A liter or so might be a year's supply for me.=20 =20 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
