Important Notes
l. Procedure should take place at 20° (+/- 0.5
C) constant temperature.
2. The weighing beaker, distilled water, pi-
pette & tips must be at the same temperature.
3. Use an analytical balance with 0.01 mgs
readability.
4. Pre-rinse the tip 3 to 5 times before pipet-
ting.
5. Divide the weight of the water by its den-
sity (at 20°C, 0.9982) to get the volume.
Recalibration
1. Place the service tool into grooves at the
base of the push button as shown below. Turn
it clockwise to increase & anticlockwise to de-
crease the volume.
2. Repeat the 'Checking calibration' proce-
dure.
STORAGE
When not in use, it is recommended that
your pipette is stored in a vertical position.
Leaving the pipette on its side can cause li-
quids to leak into the body of the pipette and
cause corrosion.
TROUBLE SHOOTING
1. Droplets left inside the tip:
—Unsuitable tip, non-uniform wetting of the
plastic: use new tip.
2. Leakage or Pipetted volume too small:
—Tip holder (cone) scratched or damaged:
change the tip cone.
—Organic solvent as liquid: aspirate and dis-
card the organic solvent several times before
actual pipetting by the same tip.
—Tip incorrectly attached: attach firmly.
—Unsuitable tip: use new tip.
—Foreign particles between tip and tip cone:
clean the tip cone.
