10 - Leak test
This test may be performed at any time to check that the
pipette does not leak, especially after performing a main-
tenance or decontamination procedure. If a pipette fails
this test, replace the O-ring and seal. After making sure
that the pipette is correctly reassembled, repeat this test.
For the P2g to P200g models:
Fit a PIPETMAN 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 P1000g, P5000g and P10mlg models:
Fit a PIPETMAN 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.
