Example
NT VARIO vacuum pump with speed control (e.g., with a rotary evap-
orator): Degassing and automatic distillation with timing
Program step 1 should be always a definite initial state, here atmospheric
pressure (ATM). To reach this state definitely, set a tickmark at ”Vent.”
and ”Step” by pressing the selection knob.
In step 2, pumping begins, attempting to reach 300 Torr/mbar as quickly
as possible (”Step”). Vacuum holds there for 10 minutes (degassing the
solvent).
In step 3, ”Auto
➜
” causes an automatic search of a boiling point in
the pressure interval between 300 Torr/mbar/hPa (depending on preset
pressure unit) and 2 Torr/mbar/hPa, followed by automatic adaptation to
changes in the boiling point. The following step starts either (1) once the
cumulative process time reaches the set limit (1 hour/60 minutes), even
if the preset pressure (2 Torr/mbar/hPa) has not been reached, or (2) if
a vacuum of 2 Torr/mbar/hPa is reached, even if the preset time has not
been completed.
Step 4 vents to atmospheric pressure as fast as possible and switches off
the control after one minute.

* If the pressure difference
between the vacuum for
degassing and the expect-
ed vacuum for distillation is
very small (distillation vac-
uum >75% of the degas-
sing vacuum), select the
function ”Auto ” (adapting
the vacuum starting from
the current pressure) in-
stead of ” Auto
➜
” (at first
searching the boiling point
automatically, and then
adapting the vacuum).
