Is a vigreaux column safe to use in a distillation apparatus under strong vacuum conditions?  I was wondering if all of those recessed glass bulbs are finicky under high vacuum and heat.  If it is not, what form of column will work under these conditions.

If Pacman had influenced us, we'd run around dark rooms eating pills and listen to repetitive music

They work wonderfully under vacuum.

thanks for the reply. 

I think this vigreaux might just become one of my favorite pieces of glass.

pressure equalized addition funnels, three neck flasks, five neck reaction KETTLES, dean stark traps, silvered vacuum jacketed columns, coiled reflux condensers, rotovaps, sintered glass buchner funnels (jointed with integral vacuum adapter).... <drool>

Sometimes I dream that I have a real lab sometimes--not just my old Fisher price kids chemistry set! cool
