A learning experience on how to distil with a vacuum fractionating or short path still.

Master Principle:

Preserving delicate temperature-sensitive aromatics and perform precision batch distillation.

Workshop contents:


  • Welcoming and Introduction of Participants
  • Workshop programme and structure
  • Scope of this workshop
  • Distilling safety - and especially for vacuum stills

The anatomy of a vacuum still and the purpose of each component
Temperature control (only possible in vacuum distillations)

  • Bath and boiler temperatures and control of boiling rate
  • Vapour temperatures
  • Coolant temperatures
  • Purpose if using the agitator

Different ways of specifying vacuum and pressure, absolute and relative vacuums

Input variables and their impacts

  • Coolant water flow - main/reflux condenser (dephlegmator) (on fractionating stills)
  • Coolant water flow - spirit condenser
  • Cold-trap cooling importance and heat input control

Practical distillation on a vacuum still (small experimental still and larger vacuum still)

  • Participation
  • Filling a still
  • Setting up a vacuum still and coolant flows
  • Starting heat and vacuum to bring to boil
  • Adjustment when boiling starts
  • Equalising/stabilizing your column
  • The heads and fraction collecting and withdrawing
  • Volume calculations for receivers
  • Opening vacuum stills and shutting down procedures

Conclusions, Q&A and discussions
