• It requires a minimum of routine attention from one operator who may carry on other work concurrently. • It allows the determination of the initial boiling point of the mixture and all points of vaporization up to about 92%. • There is negligible pressure drop through the unit. This permits reading of the pressure at a point where condensing vapors do not clog the manometer.
