1) Disassemble the pipette as described in “Main-
tenance”.
2) Immerse the components in the decontaminant
solution or wipe them according the instructions
given by the manufacturer or supplier of the
decontaminant.
3) Rinse the individual components with distilled
or sterile water.
4) Leave the parts to dry by evaporation or wipe
them with a clean lint-free tissue or soft-cloth.
5) Lubricate the piston and reassemble the pipette
according to the instructions given earlier in this
chapter.
14  LEAK TEST
This test may be performed at any time to check that
the pipette does not leak, especially after performing
a maintenance or decontamination procedure. If a
pipette channel fails this test you should replace the
faulty part (e.g. O-ring, tip-holder...) and repeat this
test, after making sure that the pipette is correctly
reassembled.
U2 to U200 and Multichannels
- Fit a Gilson Diamond Tip,
- set the pipette to the nominal volume,
- pre-rinse the tips as you would in normal use (see
“Pipetting”),
- aspirate the nominal volume of distilled water,
- hold the pipette in the vertical position and wait
for 20 seconds,
- if a water droplet appears at the end of the tip
there is a leak (see Troubleshooting),
- if you see no droplet, re-immerse the tip below
the surface of water,
- the water level inside the tip should remain
constant; if the level goes down there is a leak
(see Troubleshooting).
