The amount of heat applied
to the pot flask (boiler) through the heating mantle is called the heating
rate. The heating rate is a percentage (%) of the total heating
capacity of the heating mantle.
So if the heating rate is
set for 50% and the heating mantle has 1000 watts then then 500 watts of
heat is being applied to the pot flask.
Normally, the heating rate
is controlled by turning power to the heating mantle on and off. So
for a 50% heating rate the heating mantle will be on 50% of the time.
Choosing a heating rate is
a balance between purity and distillation speed. Slow distillation
rates give higher purity but slower throughput. Fast distillation
rates give lower purity but higher throughput. The key is to find
the heating rate that gives the required purity of the distillate while
having an acceptable throughput.
The M690 microprocessor allows the
heating rate to be preprogrammed for the start up of the distillation, and
each temperature fraction. This allows maximum flexibility in
optimizing each solvent recycling protocol.
