Distillation
From Hackteria Wiki
What it is about
Distillation is a process that separates a volatile liquid from less-volatile liquid. First there has to be some source of heating, and containment of those vapors, and then, there needs to be a cooling system that cools the more volatile liquid into a separate container.
The equipment
While traditional chemistry set ups can look very specific, as long as it maintains the above mentioned conditions, the configuration can be quite simple.
