5.2 Adjusting the finger rest
The finger rest supports the position of the pipette on the
index finger, enhancing ergonomics. The finger rest can be
adjusted by rotating it 60 degrees in both directions from the
center position (Picture 2). Usually right-handed operators
turn it left (counter clockwise) to achieve the best possible
position for the thumb to eject the tip.
5.3 Setting the delivery volume
1. Set the delivery volume using the volume adjustment
button on the top of the pipette (Picture 3). Pull the
button to activate the volume setting.
2. To increase the delivery volume, turn the button
counterclockwise. To decrease the delivery volume,
turn it clockwise.
3. Lock the volume by pushing the button down.
4. Check the volume on the display.
NOTE! Do not set volumes outside the pipette´s specified
volume range. Using excessive force to turn the volume
adjustment button outside the range may jam the
mechanism and eventually damage the pipette.
5.4 Tip attachment
0.1-10µl models
0.1-2 μl and 10 μl pipette models use 'Snap and Lip' seal tips. The tip has small
incorporated protrusions that snap on the tip fitting flange, ensuring secure tip
attachment with little force. The flexible plastic lip design seals the tip against
the tip fitting.
1. To attach the tip, guide the pipette into a ClipTip in a rack and press until
the tip is attached. The tip is attached when it snaps over the tip fitting
flange. Do not use excessive force when attaching the tips as the device
requires minimum attachment force. (Picture 4a)
2. Lift the pipette.
3. If the tip is not attached, repeat Steps 1 and 2.
20-1000µl modes
1. To attach the tip, guide the pipette into a ClipTip in a rack and
press with light force until the tip is attached. A delicate click sound
will indicate that the tip is attached. The tip is attached when the
clips* (Picture 4b) are locked to the tip fitting.
Do not use excessive force when attaching the tips as the device
requires minimum attachment force.
2. Lift the pipette.
3. If the tip is not attached, repeat Steps 1 and 2.
Incorrect use of tips
Use only ClipTip tips with an F1-ClipTip pipette.
Check that all clips are locked to ensure tip sealing.
ClipTip tips are designed for single use only.
To ensure sterility and purity of tips check that the package is unbroken.
Check that the tip is complete and unbroken. Check for foreign particles in the tip.
Check that the filter tips have filters in place and that each filter is unbroken and not tilted.
5.5 Aspirating and dispensing liquid
1. Fill a suitable vessel with the liquid to be dispensed.
2. Depress the pipetting button to the first stop (Picture 5).
3. Dip the tip under the surface of the liquid in the reservoir to a depth of about 1 cm
and slowly release the button.
