Sublimation and apparat(us/i?) along with Vacuum depth

sublimation

I went through all of the information on @Beaker’s site and I really appreciated and enjoyed it. He goes into detail on sublimation and how it can be an excellent low volume alternative to SPD. I was wondering how deep of a vacuum would be necessary to try sublimation. I don’t think I can hit 3/4 of a micron but I could probably hit 8-10 microns…

I also was looking around at other sublimation apparatus that might better fit my budget and came across one of deschem’s. I use a lot of his glassware. I wanted to know what everybody thought: https://www.ebay.com/itm/500ml-24-40-Glass-Complete-Vacuum-Sublimation-Apparatus-Lab-Capacity-Resevoir/331180151290?epid=569477826&hash=item4d1be011fa:g:uRsAAOSw4A5YpqTs:rk:18:pf:0

Since I already use a RBF and heating mantle it would better fit my current setup, but I think the chemglass sublimator (the 500$ one) certainly has a lot of advantages.

It will work, although the size of the cold finger won’t allow for much product.
