<p>[QUOTE=&quot;WeirdFishes, post: 1778886, member: 41261&quot;]Correct. After pulling the vessel into a deep vacuum there is NO moisture and NO air (oxygen in particular) inside the chamber. However nature abhors a vacuum, so what I would do would be to break the vacuum using dry nitrogen, bring pressure in the vessel (as measured by a pressure gauge attached to the vessel) to like half a psig. This will make the vessel slightly more positive in pressure than the surrounding environment which is what we want.&nbsp; Argon could also work as it is an inert gas though I am not as familiar with it as far as dessicants go.[/QUOTE]</p><p><br /></p>
