does not lead to evaporation of the solvent.
+
Set ”Maximum” pressure setting so that pump will switch off at the end
of the filtration process, or in the event that a filter cake cracks, leading
to a sudden pressure increase.
+
Start process by pressing ”START/STOP” key.
+
Tip for filtration: Adjust preset pressure to a value well above the
boiling pressure of the solvent (e.g., for water >>15 Torr (20 mbar)).
Set the maximum pressure to e.g., 375 Torr (500 mbar). Once the fil-
tration has finished, the pressure increases and the pump is switched
off automatically.
+
Select ” Pump down” function.
+
Set ”Minimum” to prevent volatile components from evaporating. The
process is stopped automatically as soon as ”Minimum” is reached.
+
Set a process time (”Duration”) if necessary.
