10 - 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 fails this test, replace the o-ring and seal.
After making sure that the pipette is correctly reas-
sembled, repeat this test.
For the P2 to P200 models:
Fit a Gilson DIAMoND Tip.
Set the pipette to the maximum volume given
in the specifications, and pre-rinse.
Aspirate the set volume from a beaker of distilled
water.
Maintain 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.
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.
For the P1000 to P10ml models:
Fit a Gilson DIAMoND tip.
Set the pipette to the maximum volume given
in the specifications.
Aspirate the set volume from a beaker of distilled
water.
Maintain 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.
