Examples of counter indications
The decimal point in the
volume of aspirated liquid
(µL or mL) is indicated by
change in colour of digits.
Black digits represent
integer numbers, and red
digits represent decimal
fractions (sizes up to 20 µL).

For maximum accuracy, the set volume must be approached
from a higher value by decreasing counter readings. Before
reaching the desired value, reduce the speed of turning
the adjustment knob to avoid inadvertently exceeding the
desired value.
7. Operating Instructions
Observing the following recommendations will ensure
maximum possible accuracy and precision of liquid sampling.
• During operation, the volume setting should be locked,
with black adjustment knob in the lower position.
• Ensure smooth and slow operation of the pipettor.
• Immersion of the tip into the sample liquid should
be kept to a minimum depth, which should remain
constant during aspiration. The recommended
immersion depths are given in the table below:
Model Volume Range (µL)
Immersion Depth (mm)

1-100
2-3
101-1,000

• The pipettor should be held in a vertical position.
• The pipet tip should be changed whenever the volume
setting is altered, and when a different liquid is to be
aspirated.
• The pipet tip should be changed if a droplet remains on
the end of the tip from the previous pipetting operation.
