Operation - Thermo Scientific F1-ClipTip 4641170 Instructions For Use Manual

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 specifi c 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.
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.
Cautions for incorrect operation
For optimum performance, make sure that the tips, pipette and solution are at the same
temperature.
Before you begin your actual pipetting, fi ll and empty the tip three to fi ve times with the
solution that you will be pipetting.
Push and release the pipetting button slowly at all times particularly when working with high
viscosity liquids. Never allow the pipetting button to snap back.
Do not hold the pipette horizontally or upside down when there is liquid inside the tip. Sample
liquid may enter the pipette, which will affect the pipetting performance and may damage
the pipette.
Operate the pipetting button gently. If it is quickly released, sample liquid may enter the pipette,
which will affect the pipetting performance and may damage the pipette.
Follow the ergonomic guidelines for laboratory work to minimize the risk of repetitive strain
injury (RSI).
5.1 ID-tag
You can mark the pipette ID-tag with your initials, pipetting application or calibration date. Remove
the pipette's module to replace the tag. Mark the label and slide the tag together with the holder
back to its slot (Picture 1).
5.2 Adjusting the fi nger rest
The fi nger rest supports the position of the pipette on the index fi nger, enhancing ergonomics. The
fi nger 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.
