The apparatus consists of an evaporating flask rotated by
sparking induction motor in a heating water bath. Vacuum distillation
of solvent at high and low temperature is achieved quickly
and efficiently by use of a fixed speed motor, which prevents
foraming and bumping of the liquid (solvent) into the evaporating
flask and also distillation under controlled atmosphere.
The evaporating flask is pear shaped to give a large surface
area of evaporation and is clamped to a glass duct which goes
through the drive unit and protudes about 120 m.m. into the
condenser. The condenser is fitted with standard joint at
the top and the bottom for receiver flask. The unit is fitted
with a quick action jack.
