Forward pipetting
1. Press the push button to the first stop.
2. Dip the attached tip into the liquid vertically by 2 to 3mm. Smoothly release the
push button.
3. Withdraw the tip slowly from the liquid - touching against the wall of the vessel
to remove remaining liquid. Place the tip on the wall of the vessel on an angle.
Dispense the liquid into the receiving vessel by gently pressing the push button
to the first stop.
4. After a short delay, press the push button to the second stop. This will empty the
tip completely and ensure accurate pipetting.
5. Release the push button to the ready position.
Reverse pipetting
Reverse pipetting is recommended for viscous solutions with a tendency to foam or
dispense very small volumes.
1. Press the push button to the second stop.
2. Dip the attached tip into the liquid vertically by 2 to 3mm. Smoothly release the
push button. This will fill the tip with an additional volume larger than the set
volume.
3. Withdraw the tip slowly from liquid - touching against the wall of the vessel to
remove remaining liquid. Dispense the liquid into the receiving vessel by gently
pressing the push button to the first stop. This volume is equal to the set volume.
4. Hold the push button in this position. The liquid that remains in the tip should not
be dispensed. The remained liquid can be discarded with the tip or delivered back
into the vessel with the original solution.
5. Release the push button to the ready position.
