the blow-out function ensuring complete delivery
of the liquid. Reverse pipetting is recommended
for highly viscous, biological or foaming liquids,
or very small volumes of liquid. A selected
volume plus an excess is aspirated into the tip.
The delivery is done without blow-out, and, thus,
the excess volume remains in the tip. The reverse
technique also facilitates the repeated delivery of
the same volume. If reverse pipetting technique is
used the pipette might need recalibration.
8.1. Forward pipetting
1. Fit the tip onto the pipette tip cone.
2. Press the operating button to the first stop.
3. Place the tip just under the surface of the
liquid (2-3 mm) and smoothly release the
operating button up to the starting position.
Wait one second. Carefully withdraw the tip
from the liquid, touching against the edge
of the container to remove excess from the
outside of the tip.
4. Dispense the liquid by pressing the operating
button to the first stop. After a short delay
press the operating button to the second
stop. This action will empty the tip.
8.2. Reverse pipetting
1. Fit the tip onto the pipette tip cone.
2. Press the operating button all the way to the
second stop.
3. Place the tip just under the surface of the
liquid (2-3 mm) and smoothly release the
operating button up to the starting position.
4. Withdraw the tip from the liquid touching
against the edge of the container to remove
excess.
5. Press the operating button smoothly to the
first stop to deliver the desired volume. Hold
the operating button at the first stop. The
liquid that remains in the tip should not be
included in the delivery.
6. Discard the remaining liquid by pressing the
operating button to the second stop.
8.3. Repetitive reverse technique
1. Follow the reverse technique steps 1 to 5.
2. Continue pipetting by repeating steps 3 to 5
as long as needed.
3. Finally discard the remaining liquid by
