14 Cleaning and Storing
14.1 Cleaning the Measuring Cell
1. Empty the measuring cell:
a. Place the filling tube in a suitable waste vessel.
b.
Filled with filling tube
: Press the pump lever to empty the
measuring cell.
Filled with syringe
: Unplug the syringe to let the sample drain off via
the filling tube.
2. Fill the measuring cell with a suitable solvent.
3. Pump the solvent through the whole measuring system several times.
4. Empty the measuring cell.
TIP:
If the cleaning is done with a syringe, move the plunger of the syringe
back and forth vigorously several times so that air bubbles add to the
cleaning action.
14.2 Cleaning Interval
The cleaning interval strongly depends on the application. For some
samples, a displacement of the previous sample by the next one suffices. For
other applications, a cleaning after each measurement might be necessary.
NOTICE
• Make sure the solvent you use for cleaning is suitable. For details on
recommended cleaning agents see section 14.2.3.
• Do not use any mechanical action for cleaning the measuring cell.
Displacing
the sample
For samples which are very similar to each other (e.g.
one type of fermenting wine after the other).
To displace the sample, empty the measuring cell after
the measurement and rinse it with the next sample before
measuring that one.
Clean your
SG-Ultra Max
thoroughly at the end of your
measurement cycle.
Cleaning
after each
measurement
For samples with different chemical properties which are
immiscible and/or difficult to remove from the measuring
cell.
