[Cz-chemistry] Need help in obtaining a suitable drawing for [[Vacuum Distillation]]

[Richard Mayes]

Milton,

I'll try to send a drawing of our vacuum distillation setup, it's quite
simpler than the Perkin Triangle, but it works.  It may be around Monday or
Tuesday before I can get it out though.
