servicing the Piston assembly
You may remove the piston assembly for cleaning pur-
poses only. If the piston assembly is changed, the pipette
must be adjusted and calibrated in a Gilson authorized
Service Center. As the models P2G and P10G contain
miniaturized parts, it is best not to disassemble these
pipettes yourself.
The piston assembly must not be autoclaved.
Remove the tip-ejector (see above).
Unscrew the connecting nut by
turning it counter-clockwise.
Carefully separate the lower and
upper parts.
Remove the piston assembly and
the seals.
Leave exposed the piston, clean
it with i sopropanol or e thanol
and lubricate lightly. For P100G,
P200G and P1000G models, lu-
bricate only the useful part of the
piston and the seals.
For P5000G
and P10mlG
, lubricate the tip of
the piston, disassemble the seals
and lubricate their internal part.
