5 Strip the pipetting tip
￭ Switch to the Move tab.
￭ Under Lift position, select Work position as Target position
and press [Start].
The lift moves upwards. Thereby the pipetting tip is stripped. It drops
into the collection container.
If the stripping of the pipetting tip does not work, then the individual
positions must be adjusted once again.
Note
Have one method with a weighing and pipetting sequence run
through. While doing so, check above all the perfect seating of the
pipetting tip on the adapter and the stripping of the tip. The viscosity of
the pipetted liquid plays a major role. Use a real sample for pipetting for
that reason.
3.20 Mounting the safety shield
The 864 Robotic Balance Sample Processor may not be operated without
a safety shield. Install it as follows:
1 Loosen the screws
￭ Unscrew the black nuts on both sides of tower 2.
2 Tighten the safety shield
￭ Pull the green 6.2751.160 safety shield over tower 2, starting
from the top.
￭ Screw the safety shield tightly with the two nuts as shown in the
following illustration.
