Safety
Cautions are marked with this symbol .
Intended use
The intended use of the device is to transfer liquids in the volume range of 1 µl to 1000 µl.
The F2 Finnpipette pipette and Finntips are designed as a component of an analyzing system
for an end user, who is responsible for validating the system to ensure reliable and safe results.
Damage to health
Follow general procedures for hazard prevention and safety instructions; e.g. wear
protective clothing, eye protection and gloves.
For use and waste disposal of hazardous (e.g. radioactive and potentially infectious)
material, follow the safety instructions and general laboratory practice.
The pipette and tips are not intended for in vivo use. Do not use the pipette for pipetting any
liquid to be injected into a human body.
Do not eject the tip towards anybody.
The Finnpipette F2 is to be used by trained personnel with required laboratory skills. The
instructions for use must be read prior to and during the use of the device (pipette and tip). The
F2 pipette can be used between +4°C and +40°C.
Incorrect dispensing results
Performance may vary due to:
a. pipetting method (forward pipetting technique recommended)
b. temperature (air, liquid, vessel, pipette, and tip)
c. pressure
d. humidity
e. operator, e.g. thumb movement, pipetting angle
f. liquid density, viscosity and vapor pressure
g. type of tip
If the pipetting performance is critical to the outcome of a specific application, the result has
to be assured with an alternative test, and if this is not an option, by duplicate testing.
The possibility of an incorrect volume delivery during pipetting cannot be entirely mitigated.

6
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.
Pipette operation
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.
Pipetting techniques
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.

Forward technique
Fill a clean reagent reservoir with the liquid to be dispensed.
1 Depress the push button to the first stop.
2. Dip the tip under the surface of the liquid in the
reservoir to a depth of about 1 cm and slowly
release the push button. Withdraw the tip from
the liquid touching it against the edge of the
reservoir to remove excess liquid.
3. Deliver the liquid by gently depressing the push
button to the first stop. After a delay of about
one second, continue to depress the push button
all the way to the second stop. This action will empty the tip.
4. Release the push button to the ready position. If necessary, change the tip and continue
pipetting.
Reverse technique
The reverse technique is suitable for dispensing liquids that have a high viscosity or a tendency
to foam easily. The technique is also recommended for dispensing very small volumes. Fill a
clean reagent reservoir with the liquid to be dispensed.
1. Depress the push button all the way to the second stop.
2. Dip the tip under the surface of the liquid in the
reservoir to a depth of about 1 cm, and slowly
release the push button. This action will fill the
tip. Withdraw the tip from the liquid touching
it against the edge of the reservoir to remove
excess liquid.
3. Deliver the preset volume by gently depressing
the push button to the first stop. Hold the push
button at the first stop. Some liquid will remain
in the tip and this should not be included in
the delivery.
4. The remaining liquid should either be discarded with the tip or pipetted back into the
container.
Repetitive technique
The repetitive technique offers a rapid and simple procedure for repeated delivery of the same
volume. Fill a clean reagent reservoir with the liquid to be dispensed.
1. Depress the push button all the way to the second stop.
2. Dip the tip under the surface of the liquid in the
reservoir to a depth of about 1 cm, and slowly re
lease the push button. This action will fill the tip.
Withdraw the tipfrom the liquid touching against
the edge of the reservoir to remove excess liquid.
3. Deliver the preset volume by gently depressing
the push button to the first stop. Hold the push
button at the first stop. Some liquid will remain
in the tip and this should not be included in
the delivery.
4. Continue pipetting by repeating steps 3 and 4.
Pipetting of heterogeneous samples
(deproteinization in blood glucose determination, for example)
Use steps 1 and 2 of the forward technique to fill the tip with blood.
Wipe the tip carefully with a dry clean tissue.

1. Immerse the tip into the reagent and depress the
push button to the first stop, making sure the tip
is well below the surface.
2. Release the push button slowly to the ready
position.
This will fill the tip. Keep the tip in the solution.
3. Depress the push button to the first stop and
release slowly. Keep repeating this procedure
until the interior wall of the tip is clear.
4. Finally, depress the push button all the way to the
second stop to completely empty the tip.
Calibration and adjustment
All Finnpipettes are factory calibrated and adjusted to give the volumes as specified with
distilled or deionized water using the forward pipetting technique. It should be noted that the
use of other pipetting techniques may affect the calibration results. The pipettes are constructed
to permit re-adjustment for other pipetting techniques or liquids of different temperature and
viscosity.
Device requirements and test conditions
An analytical balance must be used. The scale graduation value of the balance should be chosen
according to the selected test volume of the pipette:
Volume range readable graduation
under 10 µl 0.00 1 mg
10-100 µl 0.01 mg
above 100 µl 0.1 mg
Test liquid: Water, distilled or deionized, “grade 3” water conforming ISO 3696. Tests are done
in a draft-free room at a constant (±0.5°C) temperature of water, pipette and air between 15°C
to 30°C. The relative humidity must be above 50%. Especially with volumes under 50 µl the
air humidity should be as high as possible to reduce the effect of evaporation loss. Special
accessories, such as the evaporation trap, are recommended.
Procedure to check calibration
The pipette is checked with the maximum volume (nominal volume) and with the minimum
volume. A new tip is first pre-wetted 3-5 times and a series of ten pipettings is done with
both volumes. A pipette is always adjusted for delivery (Ex) of the selected volume. Use of
forward pipetting technique is recommended. The maximum permissible errors are designed for
forward method. It is recommended to calibrate all channels of the multichannel pipette, but a
suitable method is also to calibrate only the edge channels. Adjustment check prior calibration is
done using one of the middle channels. It is recommended to use the ISO8655 calibration limits
presented in the following tables or user-defined specifications.
Procedure:
1. Do 10 pipettings with the minimum volume.
2. Do 10 pipettings with the maximum volume.
3. Calculate the inaccuracy (A) and imprecision (cv) of both series.
4. Compare the results to the limits.
If the calculated results are within the selected limits, the adjustment of the pipette is correct.
