The following information applies especially to high viscous solutions:
During the blow-out (Blow), keep the rocker pressed down if the liquid is flowing out at
a slow rate to ensure that the liquid can securely flow out. If you keep the rocker
pressed during the blow-out (Blow), the piston in the pipette will remain at its lowest
position.
Wipe any outer wetting against the wall of the tube while holding the rocker pressed
down.
Leave the dispensing vessel with the rocker pressed down. The rocker may only be
released outside of the dispensing vessel. The piston will only move to its basic
position after the rocker has been released.
Press the rocker down again to repeat the blow-out (Blow) as necessary.
• Free jet dispensing may be used to dispense aqueous solutions with a volume
of approximately 20 µL or more. We recommend wall dispensing for
dispensing aqueous solutions with a smaller volume.
• Select level 8 for the Speed parameter when using use free jet dispensing and
if the geometry of the dispensing tube permits this action.
• If you dispense liquid in the free jet, the reverse stroke must also be
dispensed in the free jet. If a drop then forms on the pipette tip, it is included
in the first dispensing volume.
• For wall dispensing, trigger the reverse stroke with the pipette tips on the
tube inner wall.
• During dispensing, do not switch between free jet dispensing and wall
dispensing.
