Traditionally, vacuum distillation required electricity for heating the distilling flask and running the vacuum pump. We have done vacuum distillation using PV panels to run the vacuum pump and a parabolic reflector to heat the distillation flask via solar irradiation. Several liquids have been vacuumed distilled completely off grid. The procedure and results will be discussed.
