Method
Select method (ASTM D86, D1078, D850, DIN
51751)
Dist.Group
Select distillation group (DG 0-3, DG 4, DG
Solvents, DG 7,8, DG 6)
Condenser
Input condenser temperature.
Receiver
Input temperature to cool down the receiver
compartment. To warm the receiver chamber,
select the box and enter the desired
temperature. Note that cooling only works if the
condenser setpoint temperature is within 0.5°C
of the actual condenser temperature.
Expected Vol.
Input your expected volume.
According to the standard, 5mL before this point
heat capacity will not changed
Preheat #1
The first step of the pre-heating for the flask.
This step influences mainly the time interval up
to the first drop.
Preheat Time
Time in minutes for the adjusted first heating
step (standard 3 minutes).
Preheat #2
Second step of the pre-heating capacity for the
flask. This step influences mainly the rate of
distillation of the first 2 mL. After 2mL the
microprocessor of distillation analyzer will
regulate the desired distillation rate.
Opt. Heat #1
If distillation run has finished, (min. 30 mL are
necessary) microprocessor system of distillation
analyzer will calculate optimized value.
According to the distillation group a heating rate
will be calculated to get a time for IBP of 300 sec
in group 1-3, or 600 sec in group 4.
Opt Time
Optimized time for preheat step 1 will be
calculated by microprocessor of distillation
analyzer.
Opt Heat #2
If distillation run has finished, (min. 30 mL are
necessary) microprocessor system of distillation
analyzer will calculate optimized value to get
desired distillation rate for the first 2 mL.
Select „COPY“ to use optimized values for next
distillation run.
Extended
Plate hole
Select ceran plate (25mm, 32mm, 38mm,
50mm)
Flask Type
Select flask type (125mL, 200mL)
Distillation Rate
Input distillation rate. According to the standard,
a rate between 4 mL/min and 5 mL/min is
requested. Use 4.5 mL/min.
Final Heat Adjust
If last 5 mL of distillation run are not in the time,
correction of heating capacity upwards or
downwards is possible. Heat capacity at
constant heat (5mL before ‘Expected volume‘) is
set to 100%. Correction of ±20% is possible.
Stop At Vol.
The distillation run can be interrupted at selected
volume if the entire volume is not necessary.
Stop At Temp.
The distillation run can be interrupted at a
selected temperature if the entire volume is not
necessary.
