13. Once the distillation has started the following screen will by displayed.
On the left side of the screen is a display of the results for this distillation
including IBP (Initial Boiling Point), various distillation points and the FBP
(Final Boiling Point).
On the right side is a list of the control parameters. These may be edited
during the distillation.
Pressure Set Point is the desired vacuum level.
Initial Heat Rate is the amount of heat that will be applied to the pot flask
until the first drop is detected. The value is a percentage of the total available
Wattage for the heating mantle.
Target Distillation Rate is the desired distillation rate. ASTM D1160
method specifies an average rate of 6-8 mL/min.
Maximum Pot Temperature is the maximum pot temperature allowed for
this distillation. The maximum allowable value is 350 ºC for borosicate pot
flasks and 400 ºC for quartz flasks. If the pot is run above 300 ºC it should be
checked for strain before being returned to service.
