Cleaning And Decontamination - Gilson pipetman User Manual

8) Reassemble t he u pper p art o f t he t ip-holder a nd t he
connecting nut, and then refit to the body of the
pipette by rotating the connecting nut clockwise
until it is finger tight. Fit the O-ring (for P10M, the
seal) and reassemble the lower part of the tip-holder.
Refit the tip ejector.
The seals for P10M are fragile and can be used only once. So, after unscrewing the lower part of the
tip-holder you must fit a new seal.
 How to Lubricate the Piston (except P10M)
Use only Gilson lubricant (ref: F2070902, as supplied).
Squeeze a small quantity from the tube onto a clean, lintless cloth. Use the cloth to transfer the lu-
bricant to the piston. Ensure that the piston is evenly lubricated and that you wipe away any excess
– remember only a fine film of lubricant is required
(over the entire piston).
Maintenance operation for Multichannel models
For multichannel models, the lower part should not be
disassembled: only the push-button, the connecting
nut and the tip-ejector can be replaced.
 Changing the Tip-ejector
To remove the tip-ejector, keep both ejector locks
depressed. Pull the tip-ejector down.
To refit the tip-ejector, gently re-insert the tip-ejector
vertically into the rails of the ejector support. Pull lightly
on the tip-ejector to check the position.
 Replace the ejector spacer
1) Gently press the tabs from the ejector spacer and
remove it from the tip-ejector.
2) Insert the ejector spacer and click it to the tip-
ejector.

CLEANING AND DECONTAMINATION

PIPETMAN M is designed so that the parts normally in
contact with contaminants can easily be cleaned and
decontaminated.
As part of your quality system, you may have procedures for pipette decontamination. We recom-
mend that you refer to "Decontamination Procedures for Gilson Pipettes", which you can download
from Gilson's website.
Use alcohol (ethanol or isopropanol)
to clean up the dirt and dust on the
tip-holder!
Liquid must not enter the handle
of the pipette!
