Attach tip vertically:
Use the correct tips, in accordance with the volume
range or color code!
Make sure that the tips are firmly in place and leak tight.
When using the flexible pipette shaft, attach an alterna-
tive ejector adjustment clip if necessary.
Pipette tips are disposable products!
b.
Aspirate liquid: Hold the instrument vertically, and im-
merse the tip 2–3 mm in the liquid. The liquid is aspi-
rated by pressing the pipetting key. The arrow in the
display points upwards (aspiration).
Leave the tip immersed in the liquid for a few seconds,
so that the set volume is aspirated completely. This is
especially important when pipetting viscous media and
when using pipettes with large volumes.
