Digital display

The adjusted delivery volume is clearly indicated in the large
digital display on the handle.
Raw materials
The Finnpipette F1 is made of mechanically durable and chemically resistant materials.
F1 pipette includes components which contain antimicrobial additive silver sodium hydrogen
zirconium phosphate. Silver is known to inhibit the growth of broad spectrum of micro-
organisms. For waste disposal instructions, please contact your local environmental agency. For
more information, please contact us at info.pipettes@thermofisher.com.
Common laboratory desinfectants, like 70 % ethanol, can be used without effect to antimicrobial
treatment.
Description of tips
Finntips are recommended for use with the Finnpipette F1.
They are made of virgin natural colour polypropylene, generally regarded as the only
contamination free material suitable for tips. Finntips are also autoclavable (121°C).
Setting the delivery volume
1. Set the delivery volume using the knob on the top of the pipette.
Pull the knob to activate the volume setting.
2. To increase the delivery volume, turn the knob
counterclockwise. To decrease the delivery volume,
turn it clockwise.
3. Make sure that the desired delivery volume clicks into place.
4. Do not set volumes outside the pipette´s specified volume range.
Using excessive force to turn the knob outside the range may
jam the mechanism and eventually damage the pipette.
5. Lock the volume by pushing the knob down.
ID-tag
You can mark the pipette application, your initials, the
calibration date, etc. on the ID-tag. Remove the pipette's
module to replace the tag. Mark the label with a pencil and
slide the tag together with the holder back to it's slot.
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.
Adjusting the finger rest
The finger rest can be adjusted by rotating it 60 degrees
to both directions of the center position. Usually right
handed operators turn it left (counter clockwise) to get the
best possible position for the thumb to eject the tip. See
picture.

Pipetting techniques

Push and release the knob slowly at all times particularly when working with high viscosity
liquids. Never allow the knob 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
finger rest should rest on your index finger. Make sure that the tips, pipette and solution are at
the same temperature.
