Vacuum or reduced-pressure distillation | Distillation .

A manometer to measure the pressure (vacuum) in the apparatus, since the boiling point of a liquid varies with pressure. Two types are in common use (Fig. 15.3): the Anschutz manometer, which gives a constant reading of the vacuum throughout the distillation, and the Vacustat ®, which is used to take a 'sample' of the vacuum at a given instant.

iir a single stage pump just pumps out from your tank / jar etc. drawing it thru the pump and vents to wherever the outlet goes. A two stage pump is basicly just two pumps in series, the idea being that it will reduce the backflow of gasses into the vacuum area to thereby reduce the chance of contamination in the vacuum chamber, Those hand operated MityVac pumps really dont do such a bad job .
