Normally you need to "freeze dry" something like this. That means
slightly heating it (heat lamp through a window into the Bell jar or
vacuum chamber) and having a "cold trap", which is a cold surface
to freeze off all the moisture. You don't wantt to run all the moisture
through the mechanical pump. It takes a good, two-stage mechanical
pump to do it. You probably need to get down to about 200 microns
to freeze it all off. When you suddenly get lower pressures, you know
you're done.
