I need to test a sodium wicking system in high temperature and agitated conditions. The experiment setup seems like it is going to be pretty complicated, however, and I need some direction on where I might get a glass set-up that I could modify. The set-up is as follows:
Solid sodium pellets are placed in a glass test tube, thermally rated for up to 400 deg. C..
Oxygen is purged from the tube (argon or another inert gas introduced), and the tube is sealed (cap needs to be thermally rated for 400 C as well.)
In order to create a safety barrier between the sodium tube and the oxygen atmosphere (in the event that the tube cracks under high temperatures), The sealed sodium tube is placed inside a larger glass tube which is then filled with argon.
We now have a tube within a tube where no oxygen is present. The trick is that the sodium tube needs to be agitated. We have access to a shaking mechanism that would agitate the outer tube, but the sodium tube needs to be secured inside the outer tube. Therefore, I need a set-up with a tube inside a tube so that the inner tube is secured firmly to the outer tube.
My question is: Is there a similar type of glass set-up available to purchase that I may be able to modify? Any input on how I might do it and where I might find the necessary materials? If I can't find something I may have to construct it from scratch which will prove difficult (especially to hold up under high temperatures).
Thanks,
