Pipette Operation; Pipetting Techniques - Thermo Scientific Finnpipette F2 Guide D'utilisation

To avoid inaccurate dispensing and/or leakage, check that the tip is properly attached to
the pipette.
When rotating the volume adjustment button, do not exceed the volume range of the pipette.
Otherwise the pipette may be damaged or affect pipetting performance.
Pipetting performance cannot be guaranteed if the tip is reused.
Choose only a tip and pipette with matching color coding.
Disposal of the Materials
Follow laboratory and country-specifi c procedures for the disposal of biohazardous or radioactive
waste. Refer to local regulations for the disposal of infectious material.
Warning The tips can be potentially infectious. Dispose of all used disposable tips as
biohazardous waste.
Warning Decontaminate the pipette before disposal.
Waste disposal according to local instructions taking into account legislation in place. For more
information, please contact us at info.pipettes@thermofisher.com or your local Thermo
Fisher Scientific representative.
Regarding the original packaging and packing materials, use the recycling operators known
to you.
Setting the delivery volume
1. Set the delivery volume using the push button on the top of
the pipette. To increase the delivery volume, turn the push
button counterclockwise. To decrease the delivery volume,
turn it clockwise.
2. Make sure that the desired delivery volume clicks into place.
3. Do not set volumes outside the pipette´s specified volume range.
Using excessive force to turn the push button outside the range
may jam the mechanism and eventually damage the pipette.
Safety Label
You can mark the pipette application, your initials, the
calibration date, etc. on the safety label. Remove the
old label with a sharp needle. Mark the new label with a
pencil and slide the label back in place.
Tip ejection
To help eliminate the risk of contamination, each pipette
is fitted with a tip ejector system. To release the tip, point
the pipette at suitable waste receptacle and press the tip
ejector with your thumb.
Push and release the push button slowly at all times particularly when working with
high viscosity liquids. Never allow the push button to snap back.
Make sure that the tip is firmly attached to the tip cone. Check for foreign
particles in the tip.
Before you begin your actual pipetting work, fill and empty the tip 2-3 times with
the solution that you will be pipetting. Hold the pipette in an upright position while
aspirating liquid. The grippy should rest on your index finger. Make sure that the tips,
pipette and solution are at the same temperature.
