Remove the tip ejector. Unscrew the nut, remove
the shaft, piston assembly, seal and O-ring. Rinse
the removed parts with distilled water and dry thor-
oughly. Lightly lubricate the inside surfaces of the
seal and the O-ring with the lubricant. Reassemble
the pipette in the reverse order.
Note: The shaft, shaft nut, ejector, piston assembly,
seal and O-ring may be autoclaved at a temperature
of 121°C for 20 minutes at pressure 1 bar.
The shaft of the 5000 and 10000 models should be
autoclaved without the filter.
The handle and the outside of the pipette may be
cleaned using a cloth damped in isopropanol.
If the pipette malfunction persists after carring out the
above steps, send the pipette to your HTL service repre-
sentative.
Before returning the pipette, make sure that it is free from
any chemical, radioactive or microbiological contamina-
tion that might pose any danger during transportation
and repairing. Clean the pipette as thoroughly as possi-
ble.
