5.3 Function
5.3.1 Air Displacement Pipetting Arm (Air LiHa)
Purpose of Air
LiHa
The Air LiHa is a pipetting arm for general pipetting tasks. Aspiration and dispense of liq-
uids are based on air displacement.
Tip
Movements
Servo motors move the tips in X, Y or Z-direction.
The pipetting tips can be moved independently in Z-direction. In Y-direction, equidistant
tip spreading is possible. This enables the arm to pipette e.g. from vessels with a small cav-
ity spacing (such as a microplate) to vessels with a larger cavity spacing (such as a tube
rack) with all tips simultaneously.
Tip Types
The Air LiHa is intended for disposable tips only. Different DiTi sizes are available. The max-
imum volume of the air chamber (1250 µl) matches the largest DiTi type (1000 µl).
