Pipette technique The pipette location offset you want to use for the
Mix task.
The list of pipette techniques are defined in the
Pipette Technique Editor.
Aspirate distance
(0–100 mm)
The distance between the end of the pipette tips
and the well botttoms during the aspirate action.
IMPORTANT The labware definition must be
accurate and the teachpoint must be precise in
order for the system to position the tips at the
correct distance from the well bottom.
Dispense at different distance The option to dispense at a pipette tip height that
is different than the aspirate distance.
Select the check box to enter a value for the
dispense distance.
Dispense distance
(0–100 mm)
The distance between the tips of the probes,
cartridges, or disposable tips and the well
bottoms during the dispense action.
Perform tip touch The option to touch the tips on one or more sides
of the well.
Which sides to use for tip touch The side or sides of the well to use during tip
touch: North, South, East, West, North/South,
West/East, West/East/South/North.
Tip touch retract distance
(–20 to 50 mm)
The vertical distance for the tips to rise before
touching the sides of the wells.
Tip touch horizontal offset
(–5 to 5 mm)
The horizontal distance the tips move. The value
is based on the well diameter specified by the
labware definition.
For example, if you set a value of:
• 0, the tips move a horizontal distance equal to
the well radius
• > 0, the tips attempt to move past the well
radius, which results in a more forceful tip
touch
• < 0, the tips move a distance less than the
radius of the well, resulting in a lighter tip
touch
