Technical plasma tubes



We are most pleased to be able to offer all Allred's plasma tubes for Music Therapy research. We can also manufacture custom tubes with custom gas mixes. Unless specified, lead or soda glass with the 80% Argon, 20% Neon mix, which so many have found optimal will be used. With Pyrex and quartz, the mix will be 90% Argon, 10% Neon. Even though RF tubes must generally be excited via external electrodes, internal electrodes manifactured with aluminium getter are included on all tubes except quartz tubes. The tubes may also be used in the high voltage systems as well. Prices are approximate US dollars, shipping and handling are extra. We ship from Germany, but shipping costs are pretty affordable.
