Section 2 Using the pipette
2.1 Setting the volume
(only for variable piston pipettes)
The pipette volume is set with the push button at the end of the
handle. Turn the button anticlockwise to increase the volume
and clockwise to decrease it. Make sure that the volume
setting is correct (clicks into place) and the volume shown in
the display is completely visible.
Important Note: The given precision and accuracy only apply
for the volume range specified on the pipette. Do not set the
volume to a value outside of this range. Do not use force to
turn the push button to a volume that is outside of the specified
range. This could damage the pipette.
2.2 Tip ejection
Each piston pipette is fitted with a tip ejection system to
prevent possible contamination. Press thumb down on ejector
button and remove tip from tip cone.
