Piston Assembly (Disassembled)
Service the Piston Assembly
You may remove the piston assembly for cleaning purposes only. If the piston assembly is changed, the
pipette must be adjusted and calibrated in a Gilson-authorized Service Center. As the models P2L and
P10L, F1L, F2L, F5L and F10L contain miniaturized parts, it is best not to disassemble these pipettes
yourself.
1.
Remove the tip ejector (refer to
Change the Tip Ejector
, page 14).
2. Unscrew the connecting nut by turning it clockwise.
3. Carefully separate the lower and upper parts.
4. Remove the piston assembly, O-ring and seal.
5. Leave exposed the piston, clean it with isopropanol or ethanol and lubricate lightly.
For P20L, P100L, P200L, F20L, F25L, F50L, F100L, F200L, F250L
: lubricate only
the useful part of the piston (20 ±5 mm length) and the O-ring.
For P1000L, F300L, F400L, F500L, and F1000L
: lubricate the piston.
For P5000L, P10mL L, and F5000L
: disassemble the seals, lubricate their internal
part and lubricate the piston. Do not lubricate the O-ring.
6. Reassemble the pipette (refer to figure 18).
7. Tighten the connecting nut (turn counter-clockwise).
8. Refit the tip ejector (refer to
Change the Tip Ejector
, page 14).
