6. Start the evacuation process
Select the pressure so the boiling point of the solvent is
40 °C (see solvent table in Chapter 5).
Feed in the solution through the inlet stop cock. Customers
with a C-assembly must introduce the sample into the
evaporating flask before evacuation.
Set the rotation.
Use the quick-lift to lower the flask into the bath.
1 to 2 minutes after the set vacuum level is reached
distillation should start.
If it does not start, you will have to make operating adjust-
ments (lower the pressure or raise the bath temperature).
Ideally the condenser should be utilized between 2 / 3 and
3/4 of its capacity.
7. If the distillation slows down
Change the collection flask to rule out any risk of reverse
evaporation. Then continue the distillation as described in
point 6 (without drawing in more solution). Repeat this
process until all the solvents are distilled as required.
8. To finish
Stop the rotation, raise the flask out of the bath and aerate
the system (Aerate the system at a vacuum controller, or
at the stop cock.)
If you do not want to carry out the next distillation run
immediately, switch off the heating bath to save energy.
