Pipette
1. Choose the Pipette function.
2. Select the pipetting volume simply by pressing the scroll key up or down.
3. Accept the volume with OK. Optionally, select Speed (1 slow to 9 fast) and the speed-in starts to
blink.
4. Select the speed-in with the scroll key and accept with OK.
5. Select the speed-out with the scroll key and accept with OK.
6. Fill a clean reagent reservoir with the liquid to be dispensed.
7. Dip the tip under the surface of the liquid in the reservoir and press the trigger. The liquid is drawn
into the tip.
8. Wait until the liquid is not moving in the tip and withdraw the tip from the liquid touching it against
the edge of the reservoir to remove excess liquid.
9. To deliver the liquid, press the trigger. The blow-out is also included to empty the tip.
10. Change the tip and continue pipetting.
RPipet
With the RPipet function both, reverse and repetitive techniques, are possible.
1. Choose the RPipet function.
2. Press the scroll key up or down to select the pipetting volume.
3. Accept the volume with OK.
4. Select Speed and the speed-in starts to blink.
a. Select the speed-in with the scroll key and accept with OK.
b. Select the speed-out with the scroll key and accept with OK.
Reverse technique
The reverse technique is suitable for dispensing liquids that have a high viscosity or a tendency to
foam easily. The technique is also recommended for dispensing very small volumes.
1. Fill a clean reagent reservoir with the liquid to be dispensed.
2. Dip the tip under the surface of the liquid and press the trigger. This action will fill the tip.
3. Withdraw the tip from the liquid touching it against the edge of the reservoir to remove excess
liquid.
4. Deliver the preset volume by shortly pressing the trigger. Some liquid will remain in the tip and
this should not be included in the delivery. Blowout is displayed.
5. To empty the tip, press the trigger again.
6. Change the tip and continue pipetting.
Repetitive technique
The repetitive technique offers a rapid and simple procedure for repeated delivery of the same
volume.
1. Fill a clean reagent reservoir with the liquid to be dispensed.
2. Dip the tip under the surface of the liquid and press the trigger. This action will fill the tip.
3. Withdraw the tip from the liquid touching it against the edge of the reservoir to remove excess
liquid.
4. Deliver the preset volume by pressing and holding the trigger down. Some liquid will remain in the
tip and this should not be included in the delivery.
5. Dip the tip again to reagent reservoir and release the trigger. This action will fill the tip again.
