12 – LABNET LABPETTE FX PIPETTORS
10. Pipettor Maintenance
Depending on the applications and intensity of use, the
pipettor requires periodic maintenance. The components
exposed to corrosive vapors, such as shaft elements, should
be regularly checked and cleaned. Do not use sharp tools for
pipettor maintenance. It may cause damage to the device
and affect the user’s safety.
Cleaning
External surfaces of the pipettor such as the pushbutton,
ejector pushbutton and handgrip, may be cleaned using a
cloth dampened in isopropyl alcohol. The remaining parts
removed from the pipettor during pipettor disassembly may
be washed with distilled water or isopropyl alcohol.
NOTE:
Before using cleaning agents other than those
recommended by the manufacturer, check the compatibility
charts and consider chemical resistance of the following
plastics which form components of the pipettor: PP, PC,
POM, PA, PPS, PVDF.
Sterilization
Sterilization using an autoclave
Sterilization using an autoclave The pipettor can be
sterilized in an autoclave at 121°C for 20 minutes.
Sterilization under other conditions may cause damage to
the pipettor. It is recommended to:
• Sterilize the pipettors using an autoclave with an initial
vacuum and drying cycle.
• After sterilization, the pipettor should be dried and cooled
to room temperature.
Precision and accuracy should not alter if the pipetting
processes including autoclaving are carried out as
described in this manual. If a change in accuracy occurs, it is
recommended to:
•
Check the calibration of the pipettor after the first,
third, and fifth autoclaving cycles and then after every
10 autoclaving cycles.
Ultra Violet (UV) Sterilization
The pipettors are UV resistant. The distance from the
radiation source to the exposed element of the pipettor
should be at least 50 cm. Prolonged or intense UV exposure
can cause discoloration of pipettor parts but does not affect
its performance.
